Pesticide Screening

Even in trace amounts, chemical pesticides can be dangerous for human consumption. While certain pesticides are allowed in the cultivation of cannabis and hemp, many are not eligible for use due to known or unknown dangers of consumption. Even if you aren’t using chemical pesticides, they can still infiltrate safe crops from neighboring farms. For this reason, it’s imperative to test for pesticides in the final product.

CannaSafe tests for 66 pesticides in Category 1 and Category 2, according to California state law. We can test for additional pesticides upon request. 

What is a pesticide?

Pesticides are any substance used to deter, repel, or destroy insects or other organisms that are harmful to cultivated plants or animals. The chemicals in pesticides can endanger humans, and this is why we test for their presence in cannabis and hemp products. 

Here are some of the pesticides we test for:

Highly toxic insecticide. Used to control mites, nematodes, and aphids through soil application. In toxic amounts, it can cause cholinesterase inhibition.

Insecticide that works as an organophosphate by inhibiting cholinesterase, which is an essential enzyme that keeps the nervous system working in both humans and insects. DDVP is used to control mushroom flies, aphids, spider mites, caterpillars, thrips, and white flies.

Plant growth regulator. Typically used on trees to prevent regrowth from occurring after trimming and application of paclobutrazol. It is considered a low-risk toxicity.

Highly toxic carbamate pesticide. Banned in pellet form in ecologically sensitive areas due to its toxicity. Used to kill insects, nematodes, and mites on contact or after ingestion. Capable of killing wildlife. Highly toxic to people upon contact or inhalation, and moderately toxic through dermal contact.

Insecticide used to kill cockroaches, ants, fleas, ticks, spiders, and other insects. While having nearly zero toxicity levels for mammals and birds, etofenprox is highly toxic to freshwater fish, invertebrates, and honey bees.

Highly toxic insecticide. No longer distributed in the U.S. after its 1998 cancellation due to concerns of its a high risk in causing cancer. Before then, it was typically used for subterranean control of termites.

Carbamate insecticide growth regulator. Used for flea, mosquito, cockroach, butterflies, moths, and scaled insects. Considered to have very low toxicity for mammals, but is moderately to highly toxic to fish.

Broad spectrum agricultural fungicide used typically for powdery mildew. Causes acute toxicity if large quantities are consumed, inhaled, or induced transdermally.

HOW DO WE TEST?

In order to test for all 66 types of pesticides, we have to use two different types of analyses based on the properties of the pesticide. We test 61 pesticides via LC-MS/MS (liquid chromatography tandem mass spectrometry) and the other 5 are tested via GC-MS/MS (gas chromatography tandem mass spectrometry).
