Cannabis Lab Testing Problems Continue Nationwide

By Cannabis Industry Journal Staff

In Maine, a laboratory released a study they conducted, finding a 17% failure rate of dangerous pesticides in cannabis samples tested. The state requires testing for adult use cannabis, but not for medical cannabis. Just under 4% of adult use samples failed a pesticide screening, while over 20% of all medical samples they tested failed the same screening. Nova Analytic Labs conducted the study and found piperonyl butoxide, bifenthrin, spinosad, imidacloprid and pyrethrins in both adult use and medical cannabis samples.

Also in the Northeast, a NY Cannabis Insider investigation found labs breaking rules for reporting pesticides and other contaminants as well as companies misreporting numbers and selling cannabis that has failed tests. New York only allows outdoor cultivation to encourage environmental sustainability, but some say that rule is what is behind high microbial test failure rates. To ease the burden, New York simply removed mandatory microbial testing.

Now, Oregon is doing the same: removing microbial testing burdens because too many businesses are failing them. Back in March of this year, Oregon started to require tests for aspergillus contamination, but a legal challenge halted that rule in late August and state regulators complied, doing away with the testing requirement for now. Stakeholders in many cannabis markets, including New York and Oregon, still debate just how much of a public health risk microbial contamination in cannabis truly is.

Meanwhile in California, regulators have sent warning letters to labs threatening stiff penalties if inaccurate test results are found. While these warning letters highlight THC potency inflation and laboratory shopping, a rising concern in markets across the country, they also mention falsifying scientific data, which has been known to occur in pesticide testing results as well.

The common theme across these markets is lab testing policy at the state level and an inability of an entire industry to come to any agreement. In lieu of any federal guidelines on a national level, disjointed state policies and preventable lab testing problems like these continue.

The CBD Regulatory Environment in Europe: Part 4

By Shelley Stark

No Comments

This is the final piece of a four-part series discussing European cannabis regulations. Click here for Part One, here for Part Two and here for Part Three. Part Four wraps up the series below.

Where is the future of CBD heading?

A review of these various jurisdictions, the EU, the UK, and the USA, makes it clear that testing of CBD to ensure public safety is paramount to staying in business, and indeed to the survival of the industry. In the UK it is imperative to be active in the Novel Food licensing regime to remain on the market. In the EU, it is imperative for a legitimate market at all.

In the USA, it may very well become an imperative, if not because of the FDA or even Congress, but rather because as the U.S. market matures, lawsuits over product liability are almost inevitable, pointing to the lack of toxicology reporting or to the way a product was manufactured or marketed. Until the FDA plays a more robust role in establishing standards for the safety of CBD in food products, the best means for companies to protect themselves is with a Novel Food inspired testing regime to confirm product safety.

What this means for the CBD industry

Companies want a clear path forward for investments in the CBD sector. Litigation is predictable, especially in a litigious society like the U.S., as companies prepare themselves with toxicology reporting that satisfies the FDA. There will be clear winners and losers in the CBD market place, most likely based on a toxicology report.

The EFSA, FSA, FDA, the various state level hemp associations dotted across America and more intriguingly, businesses who see testing requirements as a legal means of ousting the less-well-financed competition, are all advocating for testing. This makes sense: There is no future in betting on the unknown. Anything short of a clear safety standard is just guessing with people’s health and thus the company’s future.

So, what are we left with?

Clearly, there is a need for a toxicology report prepared on behalf of the CBD sector. And one about CBD as a food supplement, not as a medicine. It is worth noting that Miller also remarked on how Epidiolex contained high doses of CBD. It needs to be made clear that the medical study of Epidiolex is not consistent with a study of non-medical levels of CBD when used as a supplement.

At present, the biggest challenge facing CBD product manufactures, whether in the USA, EU or UK, is the lack of controlled studies and thus the inability to illustrate the necessary toxicology reporting in their portfolio. Even in the US, the FDA has said it can’t conclude that CBD meets the standard of “generally recognized as safe” (GRAS) for use in human or animal food. Thus, the future of CBD lies in a company’s ability to illustrate by means of a study and accompanying toxicology reports that their brand is firmly in line with the required safety and data standards.

Just some fo the many CBD products in the U.S. market out there

Here is where the EU and the UK may have an advantage, through involvement in the Novel Food application and licensing procedures. The needed legal security for the marketing of CBD products can only be achieved by their approval as Novel Foods. Projected costs for an individual company registering CBD isolate and full spectrum distillate under the Novel Food guidelines requires an investment of €3.5 million. As this is prohibitively high for most companies, at the June 2019 General Assembly, the EIHA proposed the creation of a consortium, with the aim of submitting a joint Novel Food application and sharing these costs among the members.

How the “EIHA projects GmbH” Partnership Works

The founding members of the EIHA projects GmbH have a preferential partnership rate. As a partner, I am able to sub-license products or brands in the EU and this license will be valid in the UK when the application is validated and on the Union list, and is equally valid in the USA.

The Atlantic Ocean is getting smaller and it appears that the FDA might very well decide that the US needs the same European safety standards applied to products at home. Sub-licensing is clearly an inexpensive pathway for an American brand to claim toxicology and safety testing PLUS get access to the EU market. It is imperative for businesses going forward to take a serious look at their future business goals and align themselves with an advancing regulatory environment confirming their commitment to approved quality products.

The CBD Regulatory Environment in Europe: Part 3

By Shelley Stark

No Comments

This is Part Three of a four-part series discussing European cannabis regulations. Click here for Part One and here for Part Two. Part Three dives into dosage, approvals and more. Stay tuned for the final Part Four, coming next week.

But does CBD harm the liver?

Here, it is important that we compare apples to apples. Supplements are intended in addition to one’s usual diet. Medicines, on the other hand, are meant to alter a condition to solve a problem. Epidiolex is a medicine, not a supplement. According to Epidiolex the recommend dosage of Epidiolex, a highly purified form of CBD, is between 5mg and 25mg per kilo body weight per day. That means that an average 70 kilo adult would need to take between 350mg and 1750mg per day!

At this moment, even the FSA states that a recommended dosage should not exceed 70mg per day and most recommendations are much lower. This is because supplements are not medicines.

The point is that Epidiolex is an FDA-recognized medicine and should not be compared to a supplement. Supplements may range from vitamins, minerals, herbal products and botanicals, and are offered without a prescription to people who wish to maintain or improve their health. Purchasers of supplements, as the word suggests, are supplementing their diet or lifestyle, they are not seeking a doctor prescribed medicine.

The supplement or additive industry has no desire to confuse the objective of a supplement with one of a medicine. The objective of testing CBD is to confirm its usage as a supplement, so a firm line can be drawn between what is a medicine, formed to make conditional changes to the body, and what is a supplement to a normal diet.

Despite the FDA’s website warning that CBD is not a legal additive to food or drinks, at this point, the Agency seems to limit actions to claims, and not the safety of the product itself.

This position may be about to change.

The FDA has made inquiries with the European authority, EFSA, concerning testing and safety requirements. It is quite possible the FDA prefers the ‘EU approach’ over the current ‘wild west approach’ driving the American CBD industry.

In response to interview questions directed to FDA spokesperson, Courtney Rhodes says:

“CBD cannot lawfully be sold as a dietary supplement or as an ingredient in food under the FD&C Act. (Bold italics by the FDA) Food ingredients must be shown to be safe to be lawfully added to food. That means, there must be a reasonable certainty that an ingredient’s intended use won’t cause harm”.

If this is the case, one may well wonder why the FDA is not enforcing the FD&C Act. The answer might lay in great part to the specifics of the 2018 Farm Bill (formally, the Agriculture Improvement Act), where the only statutory metric for cannabis as a controlled substance is the reference to the 0.3% delta 9 THC level. Many see this poorly written bill as an open door for cannabinoids to hit the markets legally, much to the chagrin of many state lawmakers.

FDA spokeswoman Rhodes says that the 2018 Farm Bill effectively “removed hemp from [DEA] regulation.” By defining hemp as Cannabis sativa L. with a delta-9 concentration of 0.3% or less, “hemp derivatives, [like] CBD, …meet that definition of hemp and [are] not prohibited under the Controlled Substances Act.”

Thus, any enforcement on the part of the FDA is legally hamstrung due to the way the 2018 Farm Bill was written.

But is change in the air?

Research has yet to settle on “how much CBD can be consumed, and for how long, before causing harm,” says FDA Principal Deputy Commissioner Janet Woodcock. The existing regulatory framework for food and supplements are inappropriate for CBD, she says, and the FDA does not, in fact, intend to pursue rulemaking that would allow for the inclusion of CBD in dietary supplements.

So, what does the FDA intend to pursue?

While the FDA has generally focused on unsubstantiated health claims for food and beverage products, it is also on record stating that available data did not show CBD products as meeting the safety standard for a human or animal food supplement. “A new regulatory pathway for CBD is needed,” the Agency says, “that balances individuals’ desire for access to CBD products with the regulatory oversight needed to manage risks.”

What would such “a new regulatory pathway” look like? Most likely, that new testing requirements for CBD could come into effect. This could eventually mean testing requirements much like those in the EU.

Have the studies of Epidiolex, with findings based on extremely high dosage levels tainted the CBD discussion?

The structure of cannabidiol (CBD), one of 400 active compounds found in cannabis.

“The FDA is relying on pharmaceutical studies that show risks at larger doses,” says Jonathan Miller, general counsel for the U.S. Hemp Roundtable, adding that there is a decade of clear and established evidence of the safety of CBD products sold at retail. This is hard to deny: The industry has been selling CBD products for the last 10 years without any significant health issues arising. Thus, says Miller, creating a new regulatory pathway would not be necessary as the dietary supplement and food pathways are already provided for under the FD&C Act.

Authorities and industry leaders alike want regulations that promote business while at the same time protecting consumers. “The FDA’s inaction for the past year has facilitated an unregulated marketplace — which is bad for consumers and bad for business. It’s time for FDA to announce a legal pathway to market for these CBD-containing supplements and to commence meaningful enforcement against products that flout category-wide requirements for dietary supplements,” says Steve Mister, president and CEO of the Council for Responsible Nutrition (CRN), quoted on the crnusa.org website.

It is clear that the FDA does not want CBD in food and beverages and likewise claims there is no clear regulatory pathway, citing scientific data on CBD based on the Epidiolx study, which has little room for claiming CBD could be safely used as a supplement because the study is based on medicine, not a supplement.

Parallel to this, the US Hemp Roundtable and other industry stakeholders are urging the U.S. House Committee on Oversight and Accountability to move forward with an investigation into the lack of regulatory action on CBD products by the U.S. Food and Drug Administration (FDA). Does this mean that hemp lobbyist Jonathan Miller for Hemp Roundtable wants toxicology testing? “Yes,” he definitively answered.

Serious business requires the security that only toxicology reporting can give. Most of the large industry stakeholders have been engaged in toxicology testing for years, as time, not just funds, is a crucial factor. The EIHA projects GmbH began testing in 2020 and is not yet finished.

If congress and the FDA were to require toxicology reporting tomorrow, would your company be ready?

Congress Wants YOU To Make Safe Products.

By David Vaillencourt

No Comments

Recently, Congress requested detailed information regarding the regulation of CBD and other cannabinoids. This comes on the heels of frustration around federal inaction with regards to cannabinoid-containing products produced from Cannabis sativa L. plant extracts that can be classified as “hemp” products amidst the clear need for safety standards that goes above and beyond state minimum compliance requirements.

A Historical Deja Vu?

The author will be joined by his colleagues leading the Seed to Sale Safety Workshop on October 16 at the Cannabis Quality Conference. Click here to learn more. Product safety standards predate the birth of our nation (and many others). From the days of the first pharmacopeias which rival the oldest documented use of the cannabis plant, to modern regulations, the quest for safety has been a constant theme. But as the saying goes “Old habits die hard,” but so do safety issues. From peanuts to thalidomide and tobacco, we’ve seen this movie before – and it is time for a new ending.

A Universal Desire for Safety

Whether you are an investor, executive, technician or anywhere in between – nobody in the cannabis industry (and all its end uses, including industrial hemp) wants to knowingly produce unsafe products. The risks of ignoring safety are real and tangible. Whether it is 20+ years in jail for being an executive of a company that knowingly sold adulterated products and was linked to seven deaths or 10,000+ deformed children, many of whom died at birth because of a drug approved for morning sickness – there is no shortage of case studies we can learn from. Even cannabis has been known to cause injury and death in consumers – not because of the d9-THC, but the impurities. As the industry continues to innovate and develop new product form factors – whether it is new delivery methods of d9-THC in soluble beverage forms, or the rise of manufactured cannabinoids in unregulated marketplaces – it’s critical to understand the risks of your entire production process and to mitigate them. No cannabis company is immune from making costly and dangerous mistakes. It’s not just about compliance – it’s about public health and safety.

Safety Can Be a Sticky Subject

Safety is indeed a complex subject, especially when it comes to cannabis products. For instance, acceptable limits for microbial contaminants for the inflorescence of a Cannabis sativa L. plant are quite literally all over the map. What about the route of administration? Take an inhaled product (like a vape pen) vs. an ingested product (e.g. an edible). Many outdoorsy people like myself may enjoy the smell of cooking s’mores over a campfire, but the particles and VOCs can irritate our lungs, especially when exposed over long periods of time. We aren’t inhaling those s’mores – so the production of the marshmallow, chocolate and graham crackers come with different risks we need to evaluate. It’s not just about the product – it’s how it’s consumed.

Safety Standards – the Fabric of Our Society

Standards are unsung heroes of our daily lives. Whether it’s to keep planes from falling out of the sky, cribs and dressers from crushing young children, preventing train derailments or ensuring the safety of our food and medical products – standards keep us protected – just like grandma’s quilt. The absence of standards can be expensive, and anyone familiar with the accusations of d9-THC lab-shopping and inflated label claims knows that the cannabis industry is the poster child for this.

Congress has long recognized the importance of standards in protecting everyday consumers, as demonstrated by numerous legislative acts. A few notable and relevant ones to cannabis are below:

1848 Drug Importation Act: First major act that combated the importation of substandard – adulterated drugs imported from overseas into the nation which was having a major impact on soldiers of the Mexican-American War. This Act included legal requirements for drugs to meet the US Pharmacopeia’s standards for strength, quality, and purity.
1906 Food and Drugs Act: After an increase in adulterated and misbranded foods and drugs – made famous by Upton Sinclair’s The Jungle, the relentless work of Dr. Harvey Wiley, a Chief Chemist with the then US Department of Agriculture and his “poison squad” – led to significant oversight of adulterated food and drugs including legal adherence to the US Pharmacopeia and paved the way for the current FDA.
1938 Food Drug, Cosmetic Act: Shortcomings in the 1906 Food and Drugs Act were catalyzed by over 100 deaths after a wonder drug that was analogous to antifreeze led to an outcry that led to the passage of the FDC&A. From factory inspections, to strict marketing and label requirements, to legally enforceable food standards and tolerances for certain poisonous substances – the FDA was given substantial more oversight to protect the growing United States. It also expressly recognized USP quality standards for medicines with USP standards also binding for any dietary supplement manufacturer that labels their products as being compliant with USP specifications.
1994 Dietary Supplement Health Education Act (DSHEA) defined and regulated dietary supplements which carved out significant exemptions for the dietary and herbal supplement industry from most FDA drug regulations. This act has been met with significant controversy as it greatly limited the FDA’s capacity to ban or restrict supplements until evidence of a major safety or adverse event is tied to the product of concern.
1995 National Technology Transfer Advancement Act (NTTAA) – A lesser known act that is focused on standards and technology that requires participation of federal agencies in voluntary consensus standards bodies. Extending beyond foods and medicines – this act covers a broad array of infrastructure and technology regulations that ensure the fabric of our society operates (largely) without issue.

Over 1,000 ASTM standards are incorporated by reference in the US Code of Federal Regulations across nearly 30 federal agencies (searchable here), a demonstration of the value and impact public voluntary standards have in our society.

At the FDA, ASTM standards are used every day to keep us safe. Whether it is to measure the absorbency of tampons (21 CFR 801.430), enforce safety specifications of synthetic and natural wax coatings that are used to coat much of our produce, gummies and more (21 CFR 178.3770), quantifying the impurities in our bottled water (21 CFR 165.110) and many more.They have long been recognized as the de facto minimum standards that balance the need to protect consumers without imposing undue burdens on innovation by industry.

The process of developing an ASTM standard, which was developed and used to keep our trains from derailing 125 years ago, is now the home of 510+ cannabis industry specific standards. Whether it’s acceptable water activity levels in cannabis flower, a truly universal symbol to alert consumers of intoxicating cannabinoids, medical cannabis flower specifications developed in close guidance of the US Pharmacopeia, or how to apply the principles of HACCP to cannabis products, a lot of the hard work has already been done for the industry. It’s simply a matter of knowing where to look and how to use them!

The path to safe and sustainable cannabis products is clear, and the tools are available. It’s time that we learn from the past, apply the standards of the present and mitigate the risks of the future. Now more than ever before, it’s easy to make safe cannabis products and a credible marketplace not just a goal, but a reality.

The CBD Regulatory Environment in Europe: Part 2

By Shelley Stark

No Comments

This is Part Two of a four-part series discussing European cannabis regulations. Click here for Part One. Part Two analyzes the differences between the UK, the EU and the US. Part Three, coming next week, dives into dosage, approvals and more. Stay tuned for more.

EU Regulatory Environment

We Europeans look with envy at the American market and wonder, why can’t we be more like that? The differences between the American market, the UK and the EU economic zone couldn’t be more different, but changes seem to be on the horizon. While both the UK and the EU apply the Novel Food law, implementation varies significantly.

In the EU, applications are submitted to the EU Commission, and approval can take up to nine months – just for approval of the application – not the testing that will follow. And while the application carries no fee, collecting the required data just to make the application can be expensive, and can run into six figures or higher. Once the application is approved, there may still be data gaps and uncertainties, with toxicology testing that can take years to complete, and ultimately must be approved and validated by EFSA (European Food Safety Authority). The required toxicology testing is where things get really expensive, with both the EIHA (European Industrial Hemp Association) and EFSA estimating costs around €3.5 million.

The EFSA’s Panel on Nutrition, Novel Foods and Food Allergens (NDA) has received 19 applications thus far for CBD as a novel food, with more in the pipeline. According to their website, NDA chair Prof. Dominique Turck reported that they “have identified several hazards related to CBD intake” and that many data gaps need filling before evaluations can go ahead. However, she concluded, “It is important to stress that we have not concluded that CBD is unsafe as food.”

As always, with food and drug reviews, it is up to the applicant to prove that a product is safe for human consumption. And for the EU Commission, EFSA is conclusive. And while initial testing is with animals, it also includes human testing, which helps explain the high cost.

At present, the EFSA has been unconvinced by the applications submitted so far, and seeks more data regarding the effect of CBD on the liver, gastrointestinal tract, endocrine system, nervous system and on people’s psychological well-being, as well as the impact on human reproduction.

Thus, in 2019, the EIHA formed a German corporation, the “EIHA projects GmbH”, formed for the purpose of pooling partners money to pay for the application and toxicity testing. The Novel Food applications (NFAs) for CBD isolate and synthetic CBD were submitted on November 4, 2022 and full spectrum will follow in April/May of 2023. It should be noted that the application for synthetic CBD has been completely dropped as no testing was ever preformed.

The applications must be reinforced by a series of tox studies under the auspices of the EFSA and for the UK, the FSA. The EFSA will start the risk assessment as soon as the suitability check is performed. The suitability check is a process performed by EFSA to make sure that they have enough data to perform the risk assessment. According to their webpage, the risk assessment can take nine months.

In the case of the application put forth by the EIHA projects GmbH, the CBD isolate dossier will be submitted to the EFSA in September and enter the risk assessment phase. In this phase, the EFSA will go over the data and can ask for more data, should they feel it necessary. They are allowed 9 months to complete this task and submit their recommendations to the EU commission for a 27-member vote, whereby the EIHA projects GmbH application will be valid and legally binding. The EIHA projects GmbH is expecting a validation during the course of 2024. This is a huge game changer!

The application for Full Spectrum distillate should be readied by the end of 2023, whereby the EFSA should be finished with the risk assessment near the end 2024. As Full Spectrum takes into account minor cannabinoid as well as limited THC, it is more complex. It should be noted, that testing full spectrum distillate with a 0.2% THC limit, tests the limit for how much THC can be ingested by humans without side effects. This study is unprecedented and might well have an enormous impact on the issue of THC and its possible future legalization. It is also costing a further one million euros to bring to fruition.

The UK Regulatory Approach

The UK Novel Food approach differs greatly from the EU’s, which has both strengths and weaknesses. What makes the UK CBD market so robust is that the FSA allows products to be sold as long as they were on the market prior to February 13, 2020 and are linked to applications submitted before March 31, 2021. As a result, the FSA was flooded with applications – many later denied on technical grounds, in great part because they didn’t meet these terms. Currently, some 11,000 products worth a projected 1 billion GBP in revenue remain on the FSA list, having passed pre-validation while the FSA awaits the final toxicology report. Only 400 CBD products have been culled from the list, but to date, not a single application has yet been approved. Pre-validation status is incumbent upon a toxicology report, and it remains to be seen how many companies are able to produce such a report.

Important to note is that due to Brexit, a UK validation when it does come, will not be valid in the EU, but products with an EU application accepted on the Union list will be valid in the UK.

Still with a projected 1 billion GBP at stake, it is easy to why UK CBD manufacturers work to appease the FSA despite the regulatory hurdles. By keeping the door open, the UK has managed to keep investors interested in the CBD market and the public safe from unmonitored products.

This is certainly not the case in the EU, where despite a smattering of products still ducking the authorities, the EU market remains thin by comparison. Their approach has stymied growth compared to the UK where robust Novel Food regulation is in place, but approached differently.

At present, a market comparison of the EU to the UK or North America seems bleak, at least for now, but following approval, future EU-wide distribution could be highly profitable. As we inch closer to a Novel Food listing, the European market may yet prove to be one of the largest markets for the safest CBD products in the world.

The American Market

Still, it is the American market that makes our mouth water; where oils, tinctures, candies, cakes, and drinks with every cannabinoid from CBD to Delta 9, Delta 8, and HHC are available and producers are on their way to becoming millionaires. With a market currently estimated at $6 billion, forecasts reach upwards of $16 billion by 2026.

And the health-related concerns, the testing requirements? Are these limited to the UK and the EU? Let’s take a closer look! A mood of caution is emerging in the American cannabis market, that includes producers and lawmakers alike, who are pushing for stricter laws and enforcement.

In America, the FDA (Food and Drug Administration) has alerted the public to CBD’s potential harmful side effects on their website and hope to force congress to deal with the issue.

Many of their concerns validate those of the FSA and the EFSA. For example: on their website the FDA makes a reference to only one CBD product that has been approved: a medicine called Epidiolex. The FDA cites the review of the Epidiolex’s application in 2018 when they identified certain safety risks, including potential for liver damage. The EFSA requires testing on the same issue.

Is the Cannabis Industry Sitting On An Untouched Gold Mine Of Innovation?

By Pam Chmiel

No Comments

Universities across the country are working in all areas of research and development to advance cannabis cultivation, medicine, drug delivery and technology. But these innovations are collecting dust because the universities are not in the business of commercializing products in the marketplace.

In 1980, the federal government passed a law that said universities that receive federal funding, which most of them do, will have the option to own whatever intellectual property or invention they develop from that federal funding. Initially, universities resisted the idea feeling they were selling their souls to the private sector and corporate America. But opinions have changed, and the marriage between universities and industries is a common and rewarding business strategy for both sides.

I interviewed Lance Anderson, a partner at the law firm Dickinson Wright who is uniquely positioned to play matchmaker to research universities, entrepreneurs and VCs to help them uncover cannabis innovations and create partnerships. Lance is also educated in life sciences, including proprietary plants, genetics and plant-derived products, and served as in-house counsel and lead IP attorney for a large public research university system and an early-stage venture capital company.

Pam Chmiel: What led you to play matchmaker to universities and cannabis businesses?

Lance Anderson: I learned that universities are interested in commercially benefiting from some of their innovations when I worked in the technology commercialization office at Texas Tech University right out of law school.

The concept of “technology transfer for commercialization” already exists in universities and presents a vast opportunity for cannabis businesses to commercialize their innovations.

Lance Anderson, an attorney at Dickinson Wright

“Technology Transfer” agreements refer to moving technology, knowledge or innovations from one organization, such as a research university, to another entity, such as a cannabis company, through licensing agreements that grant permission to use intellectual property (IP), patents or proprietary technology for commercial purposes.

Even though legalization is sweeping the country, I’m finding that academic institutions and their administrators are concerned they will lose all federal funding and are hesitant to take the chance on a cannabis research project. They are still getting comfortable with the opportunities to work with the industry, and the farm bill act of 2018 gave them the push to do so.

And why not tap into these universities, which receive millions and millions of dollars in funding? You’re not out a lot if you properly structure your relationship with them. You do not have to pay them millions and millions of dollars to get this technology. Knowing what the university wants and how to structure that relationship is key.

Pam: What are some of the benefits a business can gain by forging a partnership with a university?

Lance:

Cannabis companies benefit by gaining access to cutting-edge research, expertise and resources that can accelerate and elevate their product development and market entry.
The association with academic institutions can help build trust among consumers, investors, and lawmakers.
Working with university research students may create a pipeline of qualified employees who may want to work for the company.
Submitting a joint proposal with a university seeking government grants may lead to additional funding for the research project.

Pam: What types of partnerships do you currently see in development?

Lance: Pharmaceutical companies have collaborated with research universities for years on drug development and undoubtedly have their eye on the cannabis industry. Federal agencies like the USDA lean on academic partnerships to develop unique plant traits to improve crop production. You’ve got institutions developing new mind-blowing genetics, like polyploid species, that allow you to fine-tune the plant traits you’re interested in. There are always advances going on.

Clemson and Cornell Universities are leading the charge in cultivation by partnering with farms to develop techniques to grow better crops and increase profitability. And interestingly, many of the land grant institutions that receive federal grants, like Mississippi State, Michigan State and Texas A&M, are now diving into plant trait development. And it’s not unrealistic to think they will transition into plant-touching technologies ripe for the cannabis industry to come in and run with it from there.

“Researchers are now getting more access to cannabis strains that are more like what we’re seeing on the market, but it’s still not where we need to be”

But the research desperately needed to move the industry forward is medical research because lawmakers want proof that cannabis has medicinal benefits before they are confident in pushing for legalization. Unfortunately, the US government has been part of the problem in making it hard to conduct research, whether clinical trials, clinical research or simple preclinical studies on cannabis. Until recently, the University of Mississippi was the only university allowed to cultivate for research. So the researchers are now getting more access to cannabis strains that are more like what we’re seeing on the market, but it’s still not where we need to be. Not even close.

Academic partnerships are not a new concept, but the cannabis industry has yet to embrace it fully. Opportunities are beginning to develop where government agencies will participate and or fund the work in cannabis from the university standpoint. The National Institute of Health has a program that’s getting kicked off for cannabis research. And they all understand and recognize that the fact we don’t have enough clinical data available is a major hindrance to the advancement of this industry.

Pam: What is legally involved in a technology transfer partnership?

Lance: Collaboration between cannabis companies and research universities can take various forms, such as research partnerships, sponsored research agreements, joint ventures, or licensing arrangements. The specific model depends on the goals, resources, and intellectual property involved in the collaboration. An attorney can structure an agreement in a manner that lets everyone slowly advance into the relationship and get satisfied with the milestones they want and at which point this thing begins to take shape.

Cannabis businesses are no strangers to utilizing multiple entities in their corporate structuring. They may have a holding company that owns the real estate, a staffing company that manages the HR for the flower-touching operations, and another that holds the intellectual property. You’re seeing an entire industry familiar with IP licensing for the first time in a long time, and universities want in by licensing their intellectual property.

The university may require a licensee to have a product in the marketplace and a first sale within two years. So that introduces the concept of perishable intellectual property rights where you can default or don’t meet the licensing requirements. That perishable concept sometimes makes it hard to raise money because the investors prefer a guarantee that you have the license and will not default.

The takeaway is universities are thirsty for partnering and looking for strategic initiatives. Universities have access to patient populations, and the cannabis industry has the business know-how to take their innovations to market. It will take some culturing of both sides to understand the opportunities. But once everyone’s on the same page, the deals will look like the licenses and joint venture deals we see now with multi-state operators.

Pam: Lance, do you have any closing thoughts for our audience?

Lance: I’ve thought about this potential synergy for years as I’ve watched these two areas I practice in often. Academic partnerships are the catalyst to move the cannabis industry forward and are right in front of us. The time is now, and I’d love to be there.

Hop Latent Viroid (HLVd) & Pathogen Diagnostics: A Comprehensive Overview

By Tassa Saldi, Ph.D.

1 Comment

Hop latent viroid (HLVd) has gained attention as the molecular cause of “dudding disease” and is causing significant economic losses in the cannabis industry.^1,2 Estimates indicate that upwards of 4 billion dollars of market value are lost each year to this pathogen alone.³ The impact of HLVd on cannabis plants necessitates the development and implementation of effective pathogen diagnostics to mitigate its spread and minimize crop damage. With collaborative research efforts, we can gain valuable insights into the characteristics, spread, symptoms and preventive measures associated with HLVd in the cannabis industry.

Viroids: A Brief Overview

Viroids are unique infectious agents composed solely of genetic material, distinct from viruses. Unlike viruses, viroids lack a protective protein layer and solely rely on the host plant for replication and spread. Their stability and ability to persist in various environments make viroids a formidable threat to plant health.

Hop Latent Viroid: Origin and Global Spread

Hop latent viroid was initially identified in hop plants in 1988⁴ and was found to be largely asymptomatic in this crop. Consequently, HLVd has spread worldwide, mostly unchecked by the hops industry. This pathogen has been identified on most continents and in some fields more than 90% of hops plants are infected.⁵ Hop latent viroid very likely jumped from hops into cannabis, due to similar genetics. The timing and mechanism of cross-species transmission to cannabis remains unknown, but the prevalence of HLVd suggests this viroid has been circulating within cannabis for an extended period. Data collected at TUMI Genomics indicates that HLVd is present in all states in the United States where cannabis is legal as well internationally including; Canada, the United Kingdom, France, the Netherlands, Thailand, Austria and Switzerland.

Symptoms and Impacts on Cannabis Plants

HLVd exhibits a wide range of symptoms, which can vary from severe to subtle, affecting the growth, leaf development, flower quality and overall vitality of cannabis plants. Understanding these symptoms is crucial for timely diagnosis and appropriate disease management strategies. However, HLVd can also present asymptomatically, especially in vegetative plants. The only way to determine if your plants are infected is by routine molecular testing.

Modes of Transmission

Mechanical Transmission: HLVd primarily spreads mechanically through contact with infected sap during activities like trimming and handling. Additionally, transmission through contaminated water and the potential role of insects, fungal pathogens and seeds in spreading HLVd have also been observed.

Seed Transmission: Although no published studies exist in cannabis describing the frequency of seed transmission, HLVd does transmit through seeds in hop plants at a rate of around 8%.⁷ Preliminary studies performed by TUMI Genomics in collaboration with EZ-genetics suggest cannabis seed transmission does occur at variable rates depending on strain and level of infection of the parent plants.

Water Transmission: It has also been observed that viroids are in high concentration in the roots⁸ and can move from the root into runoff water.⁹ Plants sharing a common water source with infected plants, such as recirculating water systems or flood and drain procedures, are at risk for transmission of the viroid.

Insect and Other Vector Transmission: The jury is still out as to whether or not insects can transmit HLVd. However, multiple viroids are transmitted via insects, so it is likely that HLVd insect transmission occurs. Recent studies also indicate that fungal pathogens, like Fusarium, can transmit viroid infections.⁶ While pathogenic fungus is a major concern for cannabis growers in its own right, limiting the prevalence and spread of fungal pathogens in your facility could help limit hop latent viroid transmission as well.

Therefore, implementing proper sanitation practices and limiting pest access can help minimize transmission risks.

Preventive Measures

Prevention plays a vital role in safeguarding cannabis crops against HLVd. The STOP program, developed by TUMI Genomics, offers a comprehensive approach that includes maintaining a Sterile environment, Testing mother plants regularly, Organizing the facility to minimize pathogen spread, and Protecting the facility’s borders from introduction of infected plant material, insects and contaminated water. More details on these preventative measures can be found here.

Pathogen Diagnostics

Protecting your plants from hop latent viroid requires accurate identification and removal of infected plants before the infection spreads to other plants. To accomplish this, several critical factors should be considered:

Type of test: HLVd and all viroids can only be detected by a molecular test (a test that detects the presence of DNA/RNA). Among common molecular tests, PCR is generally the most sensitive and accurate method. PCR can provide both a diagnosis and an approximate viroid level, allowing informed management decisions. Other types of molecular tests, such as LAMP and RPA, can formally be as sensitive as PCR, but the classic versions of these assays often suffer from false positive/negative results, reducing accuracy.

Tissue type: An important consideration for HLVd detection is the plant tissue selected for testing, especially when identifying low-level or early infections when HLVd is not yet systemic. Studies completed by TUMI Genomics and others show root tissue contains the highest levels of HLVd and is the most reliable tissue for detection of viroid infection. While upper root tissue appears to contain the highest levels of viroid, roots from anywhere in the root ball are predictive of infection. Samples taken from the leaves/foliage tend to have lower levels of viroid and may produce false negative results.

Testing frequency: Routine pathogen testing is standard practice in general agriculture and is critical to maintain a healthy cannabis crop. Testing of mother plants every 4-6 weeks for economically critical pathogens (such as HLVd) will help ensure a successful run and a high-quality product.

Disinfection Methods

Studies have shown that viroids can remain infectious for longer than 24 hours on most common surfaces¹¹ and 7 weeks in water.¹⁰ Making effective disinfection methods essential to limit the spread of HLVd. While common disinfectants like alcohol and hydrogen peroxide are ineffective against viroids, a 10% bleach solution has shown efficacy in destroying HLVd. Proper tool sterilization practices, such as soaking tools in bleach for 60 seconds, are crucial to prevent transmission during plant handling.

Hop latent viroid poses a significant threat to the cannabis industry, leading to substantial economic losses. Timely and accurate pathogen diagnostics, along with stringent preventive measures, are essential for minimizing the impact of HLVd. Regular testing, proper disinfection protocols and adherence to pathogen prevention programs can help ensure the health and vitality of cannabis crops in the face of this global pandemic.

Navigating ISO/IEC 17025: Key Considerations for Cannabis Lab Software

By Montserrat Valdes

No Comments

In some states, cannabis testing facilities must undergo a third-party audit as a condition for obtaining their license. This may involve obtaining an ISO/IEC 17025 accreditation, which requires an evaluation from a qualified auditor. Alternatively, some laboratories may undergo a voluntary audit in certain regions to showcase their competency.

ISO/IEC 17025 is a widely acknowledged global benchmark for the expertise of testing and calibration laboratories. It establishes guidelines for laboratories to showcase their technical proficiency and ability to produce precise and trustworthy results.

For cannabis testing laboratories, obtaining ISO/IEC 17025 accreditation can offer a significant edge over their rivals. Such accreditation can result in several advantages, such as improved credibility, lower operational expenses, better conformity with local and state regulations and more efficient cross-border trade.

Integrating any standard into a regulated enterprise can be a complex undertaking and ISO/IEC 17025 is no exception. This standard puts a strong emphasis on quality by requiring laboratories to exhibit their impartiality, consistency and proficiency in all aspects of their work. Compliance with ISO/IEC 17025 necessitates timely and secure data retrieval, which is difficult to achieve without an information management system. Therefore, laboratories are increasingly turning to laboratory information management systems (LIMS) to modernize their practices, improve quality and meet ISO/IEC 17025 compliance standards. This article explores the critical factors that laboratory managers and staff should consider when selecting a LIMS that can help them fulfill the demands of ISO/IEC 17025. However, let’s first discuss the sections the ISO/IEC 17025 requirements are classified into.

ISO/IEC 17025 Requirements

The ISO/IEC 17025 requirements are divided into five sections:

General Requirements (Section 4): The fourth section of the ISO/IEC 17025:2017 standard details the general conditions that laboratories must follow. This section is primarily concerned with two critical aspects: impartiality and confidentiality. The impartiality requirement mandates laboratories to remain unbiased and take measures to prevent any potential bias. Similarly, the confidentiality requirement mandates that any information collected or generated during laboratory operations must be treated as private and safeguarded adequately to prevent unauthorized access. In instances where the release of confidential information is necessary by law or contract, the laboratory must communicate such release in an appropriate and timely manner.
Structural Requirements (Section 5): In order to achieve the three key objectives of competence, impartiality, and consistent operations, this section addresses the fundamental organizational requirements of a laboratory. This entails being a legal entity with well-defined management responsibilities and documenting all activities, procedures and methods that fall within the standard’s scope. It highlights the importance of human resources by requiring laboratories to provide individuals with the necessary authority and resources to identify and rectify deviations from procedures, methods and the quality management system.
Resource Requirements (Section 6): This section highlights the crucial role of resources in helping a laboratory achieve its objectives and maintain high standards. The section covers five areas, namely personnel, facility and working environment, equipment, metrological traceability and third-party products and services. To meet the standard’s requirements, personnel must demonstrate competence and impartiality, and lab personnel must record their current training status. Lab staff should also be provided with adequate resources to perform their duties. The facility and working environment should be suitable for generating accurate analytical results, while equipment must be properly calibrated and maintained. Metrological traceability is important to establish the connection between measurement results and a reference. Additionally, it is essential to thoroughly evaluate and approve third-party products and services to ensure their suitability. Clear communication of the requirements to third parties is also necessary in this regard.
Process Requirements (Section 7): This section of the standard outlines 11 essential processes that aim to improve efficiency in laboratory operations. The processes include evaluating requests, tenders, and contracts, as well as selecting, verifying and validating methods. This section covers areas such as sampling, test item handling, and technical record-keeping. Other requirements include reporting outcomes, managing complaints and non-conforming work and controlling data and information management, which is especially important in the current digital era.
Management System Requirements (Section 8): Section 8 deals with the laboratory’s management system, which must support consistent adherence to the standard’s requirements while ensuring the quality of the laboratory results. The section offers two options for the management system: Option A for new systems and Option B for existing systems driven by ISO 9001. The section consists of eight tasks which involve activities such as documenting the quality management system (QMS), identifying and addressing potential risks and opportunities, implementing measures for improvements and taking corrective actions. The final clause of the section involves conducting an internal audit of the laboratory’s management system to ensure it complies with the standard’s requirements.

Key Considerations for Selecting a Cannabis Lab Testing Software or LIMS

A cloud-based cannabis lab testing software to manage staff training with ease

Before selecting a Laboratory Information Management System (LIMS ) for your cannabis testing lab, it is crucial to comprehend the informatics requirements of your laboratory. This involves understanding analysis necessities, limitations on reporting and data sharing, demands for instrument interfacing, requirements for sample barcoding and tracking, and procedures for ensuring quality assurance. Once all this is in place, a laboratory should take into account the following considerations:

Technology Considerations

When considering technology options, it’s important to consider future growth, data management and security and regulatory responsibilities. If a laboratory expects to grow in the future, it should consider investing in technologies that could enhance data management practices and security. The laboratory must also take into account how compliance with ISO/IEC 17025 will impact its future expansion and technological needs. To determine hardware and software investment, the laboratory must consider the type of work it will be performing and the associated regulatory and customer-centric responsibilities. It is also essential to identify the person or team responsible for addressing any potential technological problems, like setting up and maintaining software. If the laboratory wants to avoid procuring IT infrastructure and hiring IT personnel for maintaining LIMS, they should deploy a cloud-based LIMS that eliminates the need to have an elaborate IT infrastructure or dedicated IT staff.

Cybersecurity Considerations

As the need for cybersecurity continues to grow in various industries, it has become apparent that cannabis testing laboratories are also vulnerable to cybersecurity threats regardless of size. Therefore, it is important to consider additional cybersecurity measures for these laboratories. Although the ISO/IEC 17025 standard does not explicitly mention cybersecurity, it does address the proper control of data in section 7.11. The standard emphasizes that LIMS, whether hosted locally or in the cloud, should be protected from unauthorized access and tampering. To comply with the ISO/IEC 17025 standard, laboratories should integrate cybersecurity considerations into their LIMS selection process. This can be achieved by creating a cybersecurity plan and including cybersecurity controls in the user requirements specification (URS) for LIMS software. Using a pre-built URS that includes cybersecurity controls can simplify the process of evaluating and selecting informatics software for laboratories. It is important to maintain the LIMS to ensure data and information integrity, recording any security breaches or non-conformance and addressing them promptly.

Regulatory Compliance Considerations

Meeting well-designed standards like ISO/IEC 17025 can enhance a laboratory’s operational culture and assure the reproducibility and accuracy of test results. If a laboratory is considering purchasing a LIMS solution and is unsure about how it can align with ISO/IEC 17025 and other regulations and standards, they can refer to resources like ASTM E1578-18 Standard Guide for Laboratory Informatics for guidance. The laboratory’s own requirements list can then be used as a checklist for vendors.

System Agility

Laboratories should consider if the LIMS under consideration can handle adding other types of testing, protocols, and workflows in the future. A flexible LIMS that allows for configuring various aspects of the system, such as sample registration screens, test protocols, labels, reports, and measurement units, is essential. When evaluating a vendor’s system, it’s important to understand what makes it user-configurable and how easy it is to make changes. Moreover, you must check if you can make changes in the system without requiring programming skills.

Cost Concerns

For a laboratory to have a clear understanding of what is included in the sales agreement, it is important to provide an estimate or statement of work (SOW) that outlines the details of the anticipated elements with as much specificity as possible. These elements should include the cost of licensing or subscription, core items needed to comply with regulations, the total cost of optional items, and the required services such as LIMS implementation, maintenance, technical support, training, product upgrades, and add-ons. There are two main pricing models for LIMS solutions: a one-time license fee and a subscription fee for cloud-hosted LIMS. If a laboratory has an internal IT team, it may prefer the one-time fee, but a SaaS subscription may be more cost-effective if they don’t have an IT team and want to save on hefty upfront cost. To accurately reflect the various pricing nuances, the estimate or SOW should specify whether the costs are for monthly or annual subscription services, hourly support and training, or a one-time fixed cost.

The ISO/IEC 17025 accreditation offers several benefits, including improved credibility, lower operational costs, and better conformity with local and state regulations. However, integrating ISO/IEC 17025 requirements into a laboratory’s practices can be challenging. That’s where a cannabis lab testing software comes in. Laboratory managers and staff must consider several critical factors when selecting a LIMS to meet the requirements of ISO/IEC 17025. Key considerations for selecting a LIMS to meet ISO/IEC 17025 requirements with ease include technology considerations, cybersecurity considerations, regulatory compliance considerations, system agility and cost considerations. By meeting the compliance requirements of the ISO/IEC 17025 standard, cannabis testing laboratories can ensure the quality of their results and provide trustworthy services to their customers.

Building An Integrated Pest Management Plan – Part 6

By Phil Gibson

No Comments

This is the sixth and final in the series of articles designed to introduce an integrated pest management framework for cannabis cultivation facilities. To see Part One, an overview of the plan and pest identification, click here. For Part Two, on pest monitoring and record keeping, click here. For Part Three, on preventative measures, click here. For Part Four, control methods, click here. For Part Five, pest control action thresholds, click here.

This is Part 6: Emergency Response

When all prevention efforts have failed and your escalation procedures must be implemented, your emergency response document takes the stage.

Figure 1: We never want to see these at our door

It sounds obvious, but your emergency response document is your team’s guide to structure your response to an emergency. This begins with the simple definition of what is an emergency for your business. Emergencies can be to your personnel (personal injury) or your infrastructure (broken pipes/floods, power failure), and finally, a pest or pathogen outbreak that threatens the entire facility (insects/fungus, molds). Be sure to get the advice of your local service providers on the important things to put in to your response plan. This article is far from an exhaustive list, but it can get you started quickly with the basics for example purposes.

Personal Injury

Personal injuries are the events where you would call your local fire or police resources after stabilizing trauma events. Examples are chemical exposure, cuts, lacerations or broken bones from falls or crush events, burns, electric shock or earthquake or weather events. Injury response is to assess, call for medical assistance if appropriate, provide first aid and stabilize the injured, move to safety if possible, treat the injury and after the event is over and still fresh in everyone’s mind, consider what can be done to avoid the repeat of this or similar events in the future. Work those changes into your standard operating procedures.

Emergency Response to Facility Events

Figure 2: Cultivation IPM Prevention with Beneficial Insects

Whether the event is broken pipes or flooding, power failure or interruption, fire, HVAC failure or weather event, emergencies come in all sizes possible. It is likely that you built up a plan for emergency response as part of your city permitting process. Be sure to use those experts to refine your plan to include your operations.

Broken pipes start with the basics of turning off the source feeds and fixing the plumbing. If the water is actually rich fertilizer nutrients, cleaning and disinfectant is necessary as part of the drying and mop up process.

Environmental damage from fire, HVAC or weather event, lead to immediate treatment to try and save the current crops. This would include manual watering/misting, portable heater/cooler/CO2 burners. Verifying that backup power supplies turned on as planned. Are emergency fixes sufficient to power or run the systems necessary for plant life until power is returned?

Cultivation Events

This entire paper has been about pest management, so emergency is expected to mean a pest or pathogen outbreak. We defined the escalated response actions up to the point of direct action and chemical interventions in chapters four and five. Your emergency response plan takes those actions to a site wide effort. Identify the pest and location/s that are causing the crisis, isolate the infested plants, remove the infected materials, clean, disinfect, and purify the contacted surfaces. Follow your plan and contact your emergency leaders.

Emergency Response Team

Your emergency response document identifies each of your team leaders and executives that are to be contacted in the event of an emergency. These leaders should be identified in the document with contact details and methods/on-call schedules for days and times of responsibility (after normal hours and holidays included). Someone is always on-call. The personal injury, facility and cultivation lead responsible should be identified and aware that they are the assigned resource and to treat emergencies as a priority.

In Conclusion

We have covered an example integrated pest management philosophy from prevention through observation to limiting expansion to treatment and review. This continuous monitoring and learning process is a living document of standard operating procedures for any facility.

The attention of your team, their scouting observations, and attention to detail give you an opportunity to address and restrict any pest outbreak before it destroys your crop. Teach your operators well and reward them for their attention to your plan.

Clean and sterilize your facilities regularly. Preventing the emergence of pests will pay for the investment in a multitude of ways in both savings and profits. Plan your response thresholds and use traps to monitor your escalating protections. Target your treatments and remediations to match the threats to your harvests. As a last resort, apply approved chemical treatments judiciously to minimize the impact on non-target organisms.

Evaluate the effectiveness of your plan on an annual basis. Put your improvements to work for you to minimize your pest footprint and to increase your profits in every harvest.

Building An Integrated Pest Management Plan – Part 5

By Phil Gibson

No Comments

This is the fifth in a series of articles designed to introduce an integrated pest management framework for cannabis cultivation facilities. To see Part One, an overview of the plan and pest identification, click here. For Part Two, on pest monitoring and record keeping, click here. For Part Three, on preventative measures, click here. For Part Four, control methods, click here. Our final chapter, Part Six, discussing emergency response, comes out next week to wrap it all up.

This is Part 5: Pest Control – Taking Action

Previous chapters have covered the many preparations you can take to protect your facilities from pest attacks and outbreaks before they get started. This chapter will summarize the concepts of pest control thresholds and the actions you can take for the painful event when you surpass those limits (and various examples). The Integrated Pest Management (IPM) recommendations provide you with a framework for these plans.

Figure 1: Cleaning regimen, the heart of successful operations – no biofilm buildups

Preventative actions are part of your regular site operations; in other words, they are how you avoid problems before they happen. Just to hit this action one more time: cleaning must be fundamental to your facility. Water sanitation and changing filters must be done on schedule and frequently to avoid biofilm build up and nasty self-multiplying eco-systems.

For each of the rooms in your facility, identify the acceptable tolerance level for each type of pest that you may encounter. Define the intervention levels per room: preventative, direct action and escalated direct action. Follow your predefined procedures and defend your facility. Let’s cover high, medium and low tolerance example responses.

High Threshold for Tolerance

For example, the impact on your plants, your profits and your yields from the discovery of a white fly fluttering inside of one of your flower rooms may be very small. If this presence is late in your harvest cycle, your tolerance of this discovery may be very high. Your team could take preventative actions to clean the room more aggressively or to check your traps more frequently, but you are probably not going to want to invest in aggressive actions at that time in the harvest cycle.

Move from passive observation to the shake test. With sticky traps in place, shake or brush your plants. Do you see the bug counts increase on your test sheets?

Figure 2: Thrip Evidence c/o UC ANR Publication 7429

As that infestation grows, you may set a threshold for direct action (i.e. 5-10 flies per trap per week). If you reach that level, implement a treatment action with a non-chemical microbial biofungicide to stop growth in the roots or neem oil as a direct chemical action.

When you reach your escalated threshold of 10-20 flies per trap or direct plant damage is apparent, an infestation is more serious. In that event, you may choose to take steps to directly reduce the pest population with knock down sprays of approved direct chemical pesticides like citric acid or insecticidal soaps. Be sure to use your Personal Protective Equipment (PPE) for breathing and contact safety if you get into this situation.

Medium Threshold for Tolerance

Depending on the timing in your harvest cycle, the discovery of fungus gnats in your grow room may trigger a medium level alarm for you. Is the location, a small example with a minimal frequency? Is this addressable with additional attention to cleaning the area and longer dry periods in the irrigation or is this the beginnings of an infestation? Fungus gnats feed off of fungus or organic matter in soil triggered from an overly moist root environment. You may choose to react with immediate cleaning at the first existence in a room. Or you could set your “Medium” level alert status to be additional sticky trap distribution at the first visible gnat. If those counts reach 10-20 gnats per sticky trap per week, begin your foliar spray regimen with Zerotol or the equivalent.

If these counts do not respond to your treatment, meaning that the next sticky trap count reaches beyond 20+ gnats per trap or visible direct plant damage, then institute your root drench protocol with a solution of BActive 1-2 times per week until the problem is under control and the counts are reduced. If the growth continues, look to approved pesticides in your area (as an example, AzaGuard Asadirectin).

Low Threshold for Tolerance

Alternatively, you may have a unified air circulation system due to facility limitations. Your air circulation may be shared across all of your mother plants, clones, veg and flowering plant areas. In that case, any presence of an airborne fungal infection like powdery mildew would have a very low tolerance of acceptance. Selective de-leafing of the infection and increased airflow are your first defense. Any visible presence beyond that would trigger a low threshold alert and immediately start a preventative action, such as carefully removing the infected plant material much wider than a few leaves and treating the area with foliar sprays like Zerotol (hydrogen peroxide plus).

If the penetration continues or expands, treatment would escalate to minimal risk pesticide follow up and observation. Chemical oils or citric acid might be in your mix in this case.

Finally, if repetitive treatments once a week are not turning the tide, increasing to once per day or even once per ON/OFF lighting cycle until the infection is controlled. At this point, you may decide to strip the room down and start over. Clearly the choice to “throw in the towel” is a total loss of the crop, but it may be the best option relative to minimal yields and failed flowers that will not sell.

Pest Control Actions

Our Integrated Pest Management recommendations paper gives you examples of what to consider for plans with white flies, fungus gnats, root aphids, powdery mildew and biofilm on plumbing or surfaces. These follow the preventative action, direct action, escalated direct action and pesticide approaches for each example. These are options to plan for water sources, root treatment, tunneling, crawling and flying phases.

In summary this week

As covered, preventative measures are your best defense. Hire expert consultants and plan these well. Escalate your response based on your scouting activity and your plan. Add your sticky traps, de-leafing, root drench, foliar sprays or knock down sprays as defined by your pest population control actions document.

For more detail on each of these treatments, you can see examples for your integrated pest management procedures in our complete white paper for Integrated Pest Management Recommendations, download the document here.

In our final chapter, Emergency Response, we will review control thresholds and example plans for a range of problems from biofilm build up to white flies and more.

Our final chapter after will describe emergency response framework and reviewing your complete plans. See you next week.
