Amoeba leaf blight is a common and serious disease. There are four symptoms of the disease: leaf blight, blight, star-shaped and leaf sheath lesions. The former mainly.

The conidial stage was Co-lletotrichum gleosporioides (Penz.) Sacc.). The amount of germs and sporulation varies depending on the culture and light conditions. A wide range of host, in the test of the 23 families 39 kinds of plants, 9 families and 15 kinds of plant disease.
