Pesticide Screening

Pesticide screening is a laboratory testing protocol used to detect residual pesticide compounds in cannabis flower, trim, and derivatives. Rather than an aroma or sensory characteristic, pesticide screening refers to analytical testing methods—such as gas chromatography or liquid chromatography—that identify unwanted chemical residues from cultivation practices. Regulatory frameworks in licensed markets require pesticide screening results before products reach consumers. Breeders and cultivators working toward compliance in regulated jurisdictions must maintain cultivation records and choose inputs carefully to pass these testing thresholds. This classification is part of the broader quality assurance framework, distinct from organoleptic (smell/taste) evaluation.

While breeding programs focus primarily on genetics and cannabinoid profiles, breeders working in regulated markets collaborate with cultivators to ensure lineages are grown using inputs that pass pesticide screening standards. Clean genetics paired with compliant cultivation practices strengthen a strain's market viability.
