- 摘要:
- 为促进西瓜叶枯病的田间防治,选用13种杀菌剂,采用菌丝生长速率抑制法对西瓜叶枯病病原菌进行室内抑菌试验。结果表明:不同杀菌剂对西瓜叶枯病菌均有不同的抑制作用,菌丝生长抑制率最好的是50%异菌脲可湿性粉剂1 000倍液和50%咪鲜胺锰盐可湿性粉剂1 500倍液,对菌丝生长抑制率分别为97.15%和96.67%;而对菌丝生长的抑率制较强的是64%噁霜?锰锌可湿性粉剂500倍液、250 g?L-1吡唑醚菌酯乳油1 500倍、25%咪鲜胺乳油1 000倍液、80%嘧菌酯水分散粒剂2 000倍液和25%溴菌腈可湿性粉剂1 000倍液,菌丝生长抑制率分别为93.95%、93.11%、92.74%、92.34%和92.27%。试验筛选出7种防治西瓜叶枯病的低毒杀菌剂,可以在生产中交替使用。
