Symptoms mainly affect the leaves, mostly from July to September. At the beginning of infection, young leaves and old leaves appear brown dots on the front of the leaves, about 1mm in size, surrounded by green halos, and then expanded to 3-5mm. The entrapment is not obvious, and there are several or dozens of spots on a leaf. Fusion into large lesions was charred. There is a black moldy spot on the lesion, which is the sub-base of the pathogen.

Pathogen Cercospora iteodaphnes (Thum.) Sacc. Called Jingliwei vesicle, a fungus is a subphylum of the subphylum; conidiophores are clustered on a black-brown scorpion, separated by 1-3, and the size is 13-202-3 (μm). Conidiophores were bar-shaped, with 3-4 membranes, colorless, and size 13-412-4 (μm).

Transmission Pathways and Pathogenic Conditions The pathogenic bacteria in the leaf disease or diseased tissue of the mycelium overwintered, and the kiwifruit began to develop before and after the spring of the following year. The condition of entering the rainy season has expanded rapidly. In some areas, some years can cause greater losses.
