This document summarizes several common persimmon diseases: 1) Armillaria root rot, also known as oak root fungus, affects woody plants and causes root and crown rot. 2) Botrytis blight causes flowers to become spotted or discolored, buds to rot, leaves and shoots to wilt and decay. It is favored by high humidity. 3) Leaf spot diseases cause small to large irregular brown or yellow spots on leaves which may fall off if severe, though trees are rarely damaged long term. Spots can be caused by fungi, bacteria, insects or abiotic factors.
