A number of insecticides, fungicides, and acaricides are often applied to Cannabis during cultivation. Their presence in products has become a major point of health concern because they can remain on flowers and become elevated in concentrated oils. In Massachusetts, non-organic pesticides may not be used in cultivation and all production batches of finished plant material must be tested for residues of prohibited pesticides.

Samples of finished plant material must be tested for the pesticides and plant growth regulators that are commonly used in cultivation. These include Bifenazate, Bifenthrin, Cyfluthrin, Etoxazole, Imazalil, Imidacloprid, Myclobutanil, Spiromesifen, and Trifloxystrobin.

Viridis is the only laboratory in Massachusetts that analyzes 206 pesticides and plant growth regulators by using both a gas chromatograph coupled to an ion trap tandem mass spectrometer (GC-IT-MS/MS) and a high performance liquid chromatograph coupled to a quadrupole tandem mass spectrometer (HPLC-MS/MS). Our inclusive analyses include Synthetic Pyrethroid analysis to meet and exceed MassDPH testing requirements.
