降雨对灭蚕蝇一号与增效灵复配药剂防效影响试验

Control Effects of Rainfall on Miecanying-1 and Synergist Mixture

研究降雨对灭蚕蝇一号与增效灵复配药剂防治柞蚕饰腹寄蝇病防治效果的影响。试验结果表明,柞叶表面药液风干0.5 h、1 h、2 h、3 h后降雨的校正防效分别为84.5%、94.5%、92.3%、95.3%,其中药液风干0.5 h后降雨对防效影响较大,与药剂对照差异极显著,药液风干1 h后降雨对防效影响较小,差异不显著。

The experiment is to study the effect of rainfall on the prevention and controlling effect of Miecanying-1 and Synergist Mixture to Blepharipa tibialis.The results showed the correction control effect of liquid on oak leaf surface drying 0.5 h,1 h,2 h,3 h after rainfall were 84.5%,94.5%,92.3%and 95.3%respectively,among which liquid drying 0.5 h after rainfall had greater correction control effect,showing significant difference with the control.While liquid drying 1 h after rainfall had less effect,with insignificant difference.
