高效氯氟氰菊酯水乳剂防治甘蓝菜青虫试验

Experimental Research of 5% Lambda-cyhalothrin EW on Controlling Cabbage Caterpillar

研究不同浓度5%高效氯氟氰菊酯水乳剂防治甘蓝菜青虫效果。试验结果表明,5%高效氯氟氰菊酯水乳剂10～15 g/667 m2,对水40～50 kg均匀喷雾,对发生在甘蓝上的菜青虫防治效果优良,具有良好的速效性和持效性。

The effects of different concentrations of 5% lambda-cyhalothrin emulsion in water （EW） on controlling cabbage caterpillar were studied. The results showed that, the mixture 5% lambda-cyhalothrin EW （10-15 g/667 m2） and water （40-50 kg） had excellent control effect on cabbage caterpillar, and it possessed fine instant effect and lasting effect.
