Symptoms & Signs
Dry bud is a common problem in cannabis crops and affects the buds, stems, flowers, and leaves. The fungal infection starts on the inside and gradually moves outwards. The plant surface becomes soft and mushy and turns dark. After that, the entire surface shows a fuzzy, webbing mold. It hampers the water and nutrient uptake of the plant, causing its death.
Transmission
It spreads through spores that travel by means of wind, water, infected equipment, and human contact. The primary cause of dry buds is high humidity (90-100%) and low air circulation.
Time of concern
Early spring to late summer
Common hosts
Cannabis sativa
Cannabis indica
Cannabis ruderalis
