针对吡虫啉、杀虫双对水稻害虫的防治特点 ,通过室内毒力测定及室内控制试验 ,筛选出由吡虫啉和杀虫双复配的优选配方制成 1 4.5%吡虫杀微乳剂 ,其共毒系数达 562 .2 8。 1 998~ 1 999年田间防治稻飞虱、稻纵卷叶螟药效试验结果表明 ,该制剂每 667m2 使用 1 0 0~ 1 50mL的防治效果均达到91 %~ 99%。
In view of the control characteristics of imidacloprid and insecticidal double pairs of pests in rice, the 4.5% imidacloprid microemulsion was screened out from the preferred formula of imidacloprid and insecticide dual compounding through indoor toxicity test and indoor control test, The coefficient is 562. The results of field trials on control of planthoppers and rice leaf roller in China from 1998 to 1999 show that the control effect of 100 ~ 150mL per 667m2 is 91% ~ 99%.
