四种农药防治温室白粉虱的药效研究

Controlling Effects of Four Pesticides on Greenhouse Whitefly

为筛选防治温室白粉虱[Trialeurodes vaporariorum(Westwood)]的理想农药,用70%啶虫脒WG、50%吡蚜酮WP、10%吡虫.灭多威WP、60%啶虫脒泡腾WP 4种不同的农药做防治温室出口型黑色西葫芦温室白粉虱药效对比试验,以清水为空白对照。结果表明,4种农药对温室白粉虱都有比较好的防治效果,最终防效无显著差异,并且对西葫芦安全,无药害。其中50%吡蚜酮WP的防效上升比较慢,适合在虫害发生初期使用。

In order to screen out the ideal pesticide for the control of greenhouse whitefly,trials were conducted to compare the control effects of four different pesticides of 70% Acetaniprid WG,50% Pymetrozine WP,10% Imidacloprid-methomyl WP and 60% Acetamiprid WP on [Trialeurodes vaporariorum（Westwood）] for export with water as the blank control.The results showed that four pesticides had good control effects on greenhouse whitefly and there was no significant difference.They were safe to T.vaporariorum causing no phytotoxicity.Among the pesticides,50% Pymetrozine WP had slow control effect which was suitable for early pests.
