Botrytis Shoot Blight

Botrytis shoot blight causes new shoot death and brown fuzzy growth on affected shoots. You see shoots wilt and die as the fungus spreads during cool, moist conditions. The disease particularly affects tender new growth. Prune out infected shoots, improve air circulation, and maintain dry foliage conditions whenever possible.

Remove blighted tissue promptly, cutting well below visible symptoms. Improve air circulation by thinning dense growth. Avoid overhead watering, especially during bloom and new growth periods when tissues are most susceptible. For recurring problems, preventive fungicide applications timed to protect new growth can reduce infection, but cultural controls should be your first approach.
