A fungal disease caused by Botrytis cinerea that attacks dense flower structures in high humidity, causing gray mold and internal bud decomposition, and posing a major risk in outdoor and greenhouse growing.
Dakota checked for bud rot on all outdoor and greenhouse plants. He noted even a dead bug lodged in a bud can start mold, yet found almost no bud rot on the outdoor Smackdown or Banana Biscotti. Some greenhouse autos did show bud rot, requiring removal of affected buds.
