摘要
2003~2004年田间药效试验结果表明,20%氟铃·辛乳油对蔬菜上常发生的小菜蛾、菜青虫、甘蓝夜蛾、斜纹夜蛾及棉铃虫为有效药剂.有效使用浓度为2000~3000倍液,防效达70%~90%以上.与当地常用有效药剂40%毒死蜱乳油相比较,氟铃·辛的2000、2500~3000倍液大体分别相当于毒死蜱1000、2000倍液的防治效果.
The results of field trial performed in 2003 & 2004 showed that IWHP(Intermixture With Hexaflumuron and Phoxim)20EC was a kind of effective medicament on controlling five pests, Plutella xylostella(Linné)?Artogeia rapae(L.)?Mamestra brassicae(Linnaeus)?Prodenia litura(Fabricius)and Heliothis armigera Hübner, which are always found on vegetables. Its effective using concentration is between 1:2000 and 1:3000 and its control effect is over 70%~90%. Compared with chlorpyrifos 40EC, a kind of effective medicament traditionally used in the same area, the control effects of IWHP 20EC in the concentration of 1:2000 and 1:2500~3000 are about equal to that of chlorpyrifos 40EC in the concentration of 1:1000 and 1:2000 respectively.
