| 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. |
