Pathogen Identification of Angular Leaf Spot of Chestnut and Toxicity Assay of Fungicides
Abstract:
A new disease on the leaves of chestnut was found in Guangdong Province. The pathogen was identified as Colletotrichum gloeosporioides. But it was named as angular leaf spot due to its different symptom from that of anthracnose of chestnut. Assay of toxicity of 10 fungicides showed that Baoning, Pujunqing and Carbendazol had distinct inhibitive effect, followed by Yebanjing and Score.
Key words:   chestnut, angular leaf spot, anthracnose, Colletotrichum gloeosporioides, fungicides
