Pathogen Susceptibility

Pathogen susceptibility refers to a cannabis plant's inherent vulnerability to fungal, bacterial, or viral infections under cultivation conditions. This classification encompasses traits like susceptibility to powdery mildew, botrytis (gray mold), root rot, and other common pathogens encountered in indoor and outdoor environments. Breeders track susceptibility profiles as a critical cultivation factor, as some genetics show markedly higher resistance thresholds than others under identical growing conditions. Understanding a strain's pathogen susceptibility helps cultivators anticipate disease management strategies and environmental controls needed for successful harvests. Susceptibility is often environment-dependent—high humidity, poor air circulation, and temperature fluctuations increase infection risk regardless of genetic predisposition. Lineage records frequently document susceptib

Breeders working to improve disease resilience prioritize pathogen susceptibility data when selecting parent plants, often cross-breeding genetics with known resistance markers. Cultivators use susceptibility profiles to inform crop planning, ventilation design, and preventive cultivation protocols.
