Pathogen Testing

Pathogen testing is not a terpene, but rather a critical laboratory screening protocol used to detect microbial contaminants in cannabis flower and concentrates. Regulatory cannabis markets require testing for pathogens including mold species (Aspergillus, Botrytis), bacteria (E. coli, Salmonella), and other microorganisms that can compromise product safety. Testing methodologies vary by jurisdiction but commonly employ PCR, culture-based, or real-time ATP bioluminescence techniques. Genetics and cultivation practices—including environmental controls, substrate quality, and harvest timing—directly influence pathogen load in final products. Breeders and cultivators working in regulated markets must understand how plant structure, trichome development, and moisture retention traits affect contamination risk.

Breeders selecting for tight bud structure, rapid flower maturation, and lower internal moisture retention often see improved pathogen test outcomes. Cultivars with dense canopies may require adjusted airflow strategies to prevent fungal colonization, making plant architecture a secondary breeding consideration in regulated environments.
