Abstract：In order to identify the pathogenic strains of pepper anthracnose in pepper-producing areas of Sichuan，this experiment collected，isolated and identified pathogens of pepper anthracnose in Ziyang and Yanyuan，etc. 7 pepper-producing areas and adopted mycelium growth rate method to test the indoor toxicities of 10 fungicides on Capsicum anthracnose．This study also adopted in vitro fruit method to measure the control impact of 6 fungicides on Capsicum anthracnose．The results indicated that the isolated pathogens of pepper anthracnose from these 7 pepper-producing areas were all Colletotrichum scovillei．C. scovillei hypha were highly sensitive to prochloraz，tebuconazole，fluconazole，difenoconazole，fluazinam and mycloconazole．All these 6 fungicides had better prevention and control effects on pepper anthracnose．The order of their effects from high to low was prochloraz（95.66%）＞ tebuconazole（92.43%）＞ fluconazole（81.00%）＞ mycloconazole（75.29%）＞ fluazinam（72.40%）＞ difenoconazole（67.67%）．
