摘要
小菜蛾(Plutella xylostella L)是十字花科蔬菜主要害虫之一,其易对单一药剂产生抗性。通过对小菜蛾4种单剂及其两两组合混用防治效果的研究,结果表明:在1.8%爱福丁乳油40 ml/667 m2、2.5%功夫水乳剂40 ml/667 m2、10%除尽悬浮剂30 ml/667 m2和15%安打悬浮剂30 ml/667 m2 4种单剂中,10%除尽悬浮剂30 ml/667 m2防治小菜蛾效果最好。两两混用时10%除尽15 ml/667 m2+15%安打15 ml/667 m2配方的防治效果最好。
Diamondback moth (Plutella xylostella L) is one of the major insects for cruciferous vegetables, easily developing resistance to single chemical. Study on the control effects of four single chemicals (1.8%AiFuDing Ee, 2.5% Cyhalothrin EW, 10%Chlorfenapyr SC and 15% Indoxacarb SC) and which combined of two against diamondback moth respectively. The results showed that 10% Chlorfenapyr SC had the best effect in four single chemicals, and 10% Chlorfenapyr SC combined 15% Indoxacarb SC had the best effect in mixture chemicals.
