| Abstract: | Field trials showed that mixed abamectin had good effect on controlling the insect in veg- etable crops. Spraying 2 000-3 000 times dilution of 36% phoxim abamectin EC, the effect of controlling Putella xylostella L. was 89.7%-94.9%, it was apparently better than that of 3 000 times dilution of 1.8% abamectin or 1000 times dilution of 40% phoxim. With the dosage of 42-53 ml/667 m2 of 1.2% hyper- tonic abamectin betacypermethrin, the effect of controlling Laphygma exigua Hubner was 90% or so, which was 2.8-5.9 percent points higher than that of applying 50 ml 0.9% abamectin EC or 45 ml 4.5% beta- cypermethrin EC in 667 m2. Against Lriomyza satirae Blanchard, the controlling effect of 3 000 times di lution of 26% chlorpyrifos. abamectin was above 93% afer 3-7 days. |
