Effects of the Equal Chemical Pesticides mixture on Nilaparvata lugens

The effects of equal pesticide mixture against Nilaparvata lugens were studied in this paper. The results revealed that the best effects of the mixture of 48% lorsban EC and 5% regent SC,48% lorsban EC and 2% abamectin EC were obtained. BPH mortality correction of 3 concentrations all reached about 95% and 100% after 24 and 48 hours,respectively. Though the mixture of 5% regent SC and 2% abamectin EC had a low effect after 24h, 100% mortality after 48h was observed. The application of the equivalence pesticides mixture not only reduced the pressure of choosing insecticide,but also delayed the insecticides resistance of Nilaparvata lugens. In addition,this method had a good effect on other pests an reducing cost.
