摘　　要：采用室内离体测定和田间试验的方法,进行了75%肟菌·戊唑醇对向日葵核盘菌的室内毒力测定和田间防治菌核病的效果研究。结果表明,75%肟菌·戊唑醇对核盘菌有很好的抑制效果,有效浓度(EC_(50))为0.0370μg/mL。其对向日葵菌核病具有很好的田间防治效果,用量在450 g/hm^(2)时效果最好,防效为92.78%;始花期用药防治效果好于其他时期;以现蕾期、始花期、盛花期和开花末期各喷药1次最佳,具有明显的增产效果。测产结果表明,喷施4次75%肟菌·戊唑醇处理的产量明显高于空白对照和常规药剂异菌氟啶胺对照,分别增产170.62%和28.79%。The indoor virulence test of 75%trifloxystrobin·tebuconazole on Sclerotinia sclerotiorum and the field control effect of Sclerotinia were studied by indoor in vitro determination and field experiment.The results showed that 75%trifloxystrobin·tebuconazole had a good inhibitory effects on S.sclerotiorum,and the EC_(50) was 0.0370μg/mL.It had a good field control effects on sunflower Sclerotiniose,and had the best control effect at 450 g/ha,with a control effects of 92.78%.The control effects in the flowering period was better than that in other periods;Moreover,the prevention effects of spraying once at the bud period,flowering period,full bloom,and the late flowering period was the best,and it had obvious increasing effects in yield.The production results showed that the yield of 75%trifloxystrobin·tebuconazole sprayed four times was significantly higher than those of the CK and the isobacterium fluridamine treatments,and the yield increased by 170.62%and 128.79%,respectively.
