摘　　要：为明确四川辣椒产区辣椒炭疽病致病菌株,筛选有效防治药剂,采集并分离鉴定了资阳、盐源等7个辣椒产区的辣椒炭疽病菌,采用菌丝生长速率法测定10种杀菌剂对辣椒炭疽病菌的室内毒力,采用离体果实法测定6种杀菌剂对辣椒炭疽病的防治效果。结果表明,7个辣椒产区分离到的辣椒炭疽病菌均为Colletotrichum scovillei;C.scovillei菌丝对咪鲜胺、戊唑醇、氟环唑、苯醚甲环唑、氟啶胺、腈菌唑敏感性较高;6种杀菌剂对辣椒炭疽病均有较好的防治效果,防效由高到低依次为咪鲜胺(95.66%)>戊唑醇(92.43%)>氟环唑(81.00%)>腈菌唑(75.29%)>氟啶胺(72.40%)>苯醚甲环唑(67.67%)。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%).
