Pesticide Residue Testing

Pesticide residues from crop protection products applied during cultivation can persist on cannabis flower and concentrate in finished products. While some pesticides may be legally used in agriculture, many are inappropriate for cannabis or pose health risks when inhaled or ingested at elevated levels.

Our Analytical Scope

Analytica Inc. screens for 66 pesticide compounds identified by the Minnesota Office of Cannabis Management as substances of concern. Our multi-residue methods use gas chromatography-mass spectrometry (GC-MS/MS) and liquid chromatography-mass spectrometry (LC-MS/MS) to simultaneously detect dozens of pesticides in a single analysis.

Pesticide Categories Tested:

Insecticides: Organophosphates, carbamates, neonicotinoids, pyrethroids
Fungicides: Triazoles, strobilurins, and other antifungal agents
Miticides/Acaricides: Products targeting spider mites and other pests
Plant Growth Regulators: Compounds like paclobutrazol and daminozide
Synergists: Piperonyl butoxide and similar potentiators

Action Limits

Each pesticide has an established action limit ranging from 0.1 to 2 ppm. Products fail testing if any single pesticide exceeds its specified limit. These limits are based on toxicological data and exposure assessments to protect consumer health.

Input Material Tracking Required

Minnesota regulations require cultivators to disclose all pesticides applied to each batch through the statewide monitoring system. This information guides our testing approach and helps ensure comprehensive screening.
