摘要
田间药效试验结果表明:40%氯虫.噻虫嗪水分散粒剂每667 m2使用8 g处理对三化螟的防治效果达92.12%,明显高于其单剂及对照药剂,使用量8、10 g处理对稻飞虱连续两年防治效果均在90%以上;使用量8 g处理的水稻产量明显高于其单剂及对照药剂,表明其对水稻具有明显的增产效果。
The plot test results showed that the control efficiency of the mixture of chlorobenzamide and thiamethoxam at 8 g/667 m2 were 92.12% against Tryporyza incertulas（walker） which were obviously higher than that of the individual treatments of two insecticides and the standard insecticide.The control efficiency of the mixture at 8,10 g/667m2 were more than 90% against Nilaparvata lugens Stal for two consecutive years.Meanwhile,the yield increase effect of the mixture at 88 g/667m2 to the rice was also discovered and the yield was more than that of the individual treatments of two insecticides and the standard insecticide.
