Pesticide Screening

Pesticides are used in commercial cannabis grow operations to kill insects and spiders that thrive on cannabis plants. Pesticides are carcinogenic and mutagenic, causing serious harm to cannabis consumers, especially immuno-compromised medicinal cannabis users. ACS offers the most sensitive and comprehensive pesticide screening and confirmation available utilizing Ultra High Performance (UPLC) Liquid Chromatograph-Tandem Mass Spectrometry (MS/MS). Offering excellent sensitivity and throughput, the ultra-low detection limits provided by ACS proprietary methodology make this technique ideal for the analysis of pesticides commonly employed during cannabis cultivation.

SPECIALIZED PESTICIDE TESTING

MATRIX: Flowers/Plants, Derivative Products and Edibles
INSTRUMENT: LCMS/MS
ANALYTES: 3 count

  • Paraquat
  • Diquat
  • Glyphosate

Glyphosate, paraquat and diquat are types of pesticides known as herbicides, which chemically kill weeds and regulate plant growth. Glyphosate in particular is one of the world’s most widely used herbicides and recently made headlines as the primary toxic chemical in Monsanto’s Roundup fertilizer. In August 2018, jurors voted unanimously that glyphosate in Roundup was responsible for causing a school grounds-keeper’s lymphoma. 

But glyphosate is still federally legal in agriculture and today’s farmers often spray it in conjunction with paraquat or diquat. This double knockdown method ensures that any weeds that survive glyphosate will die once they’ve been sprayed for a second time with paraquat or diquat. Double knockdown also prevent plants’ from developing glyphosate resistance. But the presence of herbicides can be very harmful to human health. Regardless of how carefully you spray your crop, you can only be sure that your hemp or cannabis product is safe by testing with an accredited laboratory like ACS.

Why It Matters

samples for glyphosate testing

HEALTH

The recent glyphosate (Monsanto) ruling is backed by several scientific studies, which indicate that this herbicide may increase the risk of cancer with particular links no non-Hodgkin lymphoma. Other research suggests that glyphosate may also be an endocrine disruptor with links to liver disease, birth defects, reproductive issues, and gut health concerns. 

Regarding paraquat, this supplementary herbicide has been shown to be highly toxic by inhalation and moderately toxic when ingested with research linked to parkinson’s disease, cancer and lung diseases. Diquat on the other hand is lower in toxicity but may be a moderate to severe eye irritant when applied topically. The bottom line is that the presence of any of these herbicides in cannabis flower, oils or edibles may compromise your brand and put your customer’s health at risk.

FEDERAL COMLIANCE

Regarding marijuana, currently there are no federal standards related to pesticide use or testing because it is still federally banned. Hemp however, is now legal and under review. The Environmental Protection Agency (EPA) is currently reviewing 10 pesticide applications for use in hemp, with active ingredients that the EPA previously determined safe under “any reasonably foreseeable circumstances.” None of the applications contain glyphosate, paraquat or diquat–however that may change in the coming year.

STATE COMPLIANCE

At a state level in Florida, you can only use pesticides on medical cannabis if the chemicals are registered with the Florida Department of Agriculture or the federal EPA. Florida law also requires that you test your medical marijuana to ensure there are no residual pesticides above the allowable limits.  Regarding pesticides in hemp, Florida is in the process of establishing rules via the state hemp CBD program. In that bill, Florida’s Senate proposed acceptable limits for certain pesticides–but paraquat, diquat, and glyphosate do not appear on that list.

Since the federal government and state of Florida have not determined safe levels of glyphosate, paraquat or diqua, you want to be sure that your product 100% clean. Moreover, your customers want proof that their hemp or cannabis product is safe to use.

WE TEST CANNABIS & HEMP

  • Soil
  • Plants
  • Smokable Flower
  • Extracts & Concentrates
  • Edibles
  • Topicals

HOW WE TEST

We test hemp and cannabis plants, flowers, extracts and edibles for paraquat, diquat and glyphosate along with 61 other pesticides using the liquid chromatography–mass spectrometry LC/MS/MS method. First, we extract pesticides from the samples into a solvent. Then we utilize state-of-the-art machinery to initiative the ionization process where we identify and quantify these pesticides with high specificity.

We deliver precise results within 2-5 days.  

HOW TO SUBMIT A SAMPLE FOR TESTING

The process to submit a sample of your flower or product is easy. Plus, if you’re in Florida, you can request our courier service from anywhere in the state. Simply request your test and we’ll review the submission process or arrange to collect a sample right away.
