草莓炭疽病病原菌的鉴定及防治药剂筛选(英文)

[目的]鉴定草莓炭疽病的病原菌并进行防治药剂筛选。[方法]对江苏省句容市草莓炭疽病病菌进行分离和鉴定,确定草莓炭疽病病原为半知菌亚门胶孢炭疽菌。采用室内菌丝生长抑制法测定了几种药剂对草莓炭疽病菌(Colletotrichum fragariae)的毒力,并进行了田间防治试验。[结果]咪鲜胺、吡唑醚菌酯、己唑醇在室内的作用效果较好,25%吡唑醚菌酯EC2000倍液、24%嘧菌·己唑醇(嘧菌酯∶己唑醇=1∶2,下同)SC1500倍液,25%咪鲜胺EC的田间防效显著。[结论]该研究为实际生产中药剂交替使用提供参考。

Identification of Strawberry Anthracnose Pathogens and Screening of Germicides

[Objective] This study aimed to identify strawberry anthracnose pathogens and screen appropriate germicides. [Method] Strawberry anthracnose pathogens in Jurong City of Jiangsu Province were isolated and identified. The toxicities of sever-al germicides to Col etotrichum fragariae were determined with indoor mycelial growth inhibition assay. Field control test was preformed to further verify the control efficacy of germicides. [Result] The isolated strawberry anthracnose pathogenic strains were identified as C. gloeosporioide from genus Col etotrichum of subphylum Deuteromycotina. Prochloraz, pyrazole Kresoxim and hexaconazole al exhibited good indoor control effects; 25% pyrazole Kresoxim EC2000-fold solution, 24% azoxys-trobin＆#183;hexaconazole （azoxystrobin∶hexaconazole=1∶2） SC1500-fold solution and 25%prochloraz EC1000-fold solution al exhibited significant field control efficacy. [Con-clusion] The study provides reference for the alternate use of germicides in actual production.
