藏品描述：病原菌感染柿樹新生葉片，但病斑出現於七月以後的高溫季節，初期為淡黃色斑，後期轉為褐色，並受葉脈侷限成角斑。高濕環境下於病葉背面形成灰色黴狀物，為病害特徵。
The spots are limited by the veins and so become angular in shape. The disease developing on the leaves generally contain dead tissue and fungal spores may begin to develop on the dead areas or older spots. Leaf blight typically is not a serious threat to persimmon trees but if the infection is severe, it can cause infected foliage to yellow and drop from the branches.
