Field Guide to Hemp (Cannabis sativa) Diseases
Kevin Korus, Wael Elwakil, Nicholas Dufault, and Zachary Eldred
Industrial hemp is Cannabis sativa that contains < 0.3% THC and can be legally grown with permits in Florida. The plant may be grown for flower, grain, or fiber production. Other than the lower THC levels, hemp is the same plant botanically as marijuana. Because this plant has long been on the Schedule 1 controlled substance list in the U.S. (United States), knowledge of pests and diseases is limited, and labelled control measures are almost non-existent. This publication provides information and general management recommendations for hemp diseases found in Florida. Management options are currently limited as there is a lack of resistant varieties and other management strategies for industrial hemp production.
