A review of Cannabis diseases...Journal of the International Hemp Association
Diseases of Cannabis are caused by organisms or abiotic sources.
Organisms include fungi (first and foremost), nematodes, parasitic plants, bacteria, and viruses.
Abiotic (non-living) causes include nutrient deficiencies, pollutants and genetic diseases.
Different diseases prevail in different crops (e.g., drug cultivars versus fiber cultivars).
Disease prevalence is also modulated by geography and climate. The claim that Cannabis has no diseases is not correct, Cannabis suffers over 100 diseases, but less than a dozen are serious.
Serious diseases include gray mold, hemp canker, damping off, assorted leaf spots, blights, stem cankers, root rots, nematode diseases, broomrape, macro- and micronutrient deficiencies, and genetic diseases.
Environmentally stressed plants become predisposed to diseases.
Stress incudes drought, insufficient light, untoward temperatures, or growing plants in monoculture.*
