| 摘 要： | 为筛选防治水稻稻曲病(Ustilaginoidea virens)的高效、低毒、安全杀菌剂,采用田间试验对戊唑醇等5种杀菌剂的田间药效进行了比较。防治,试验结果表明:5种试验药剂在水稻齐穗期施药1次,收割前5d调查,5%井冈霉素A可溶粉剂、75%肟菌·戊唑醇水分散粒剂、24%腈苯唑悬浮剂、43%戊唑醇悬浮剂、25%氰烯菌酯悬浮剂对稻曲病的相对防效分别为95.2%、85.1%、82.4%、73.6%、70.3%。在试验条件下,5种供试药剂对水稻后期生长无药害。

| Abstract: | In order to screen highly effective,low toxic and safe fungicides for controlling rice false smut,five fungicides were tested in field efficacy trials.The results showed that each fungicide was applied once at the full heading stage of rice and investigated five days before harvest.The relative control effects were 95.2%,85.1%,82.4%,73.6%and 70.3%for Jinggangmycin A 5%SP,Trifloxystrobin+tebuconazole 75%WG,Fenbuconazole 24%SC,Tebuconazole 43%SC and Phenamacril 25%SC,respectively.Under the trial conditions,no negative effect had been found on five tested chemicals to the later growth of rice. |
