摘  要:
为减缓害虫对吡虫啉的抗性,扩大农药杀虫普,提高药效,进行了吡虫啉和溴虫腈的复配悬浮剂研究。采用单一筛选的方法结合热贮后指标的检测,筛选润湿分散剂和增稠剂;采用冷热贮及破坏性试验来验证配方的稳定性。20%吡虫啉.溴虫腈SC的最佳配方为:10%吡虫啉原药、10%溴虫腈原药、2%7227-A、0.5%BC/10、0.2%黄原胶、0.5%硅酸镁铝、5%尿素、0.5%有机硅消泡剂630和0.1%防腐剂,去离子水补足100%。所得悬浮剂通过检测得出产品各项指标均符合悬浮剂国家标准,所用方法可行。

摘  要:
To reduce the resistance of pests to Imidacloprid,expand the scope of insecticide and improve efficacy,we studied on formula of imidacloprid and chlorfenapyr SC.The best wetting and dispersing agent and thickener was determined by single-factor tests and the test results of hot storage.The stability of the formula 20%imidacloprid and chlorfenapyr was verified by cold and hot storage and destructive test.The best formula:imidacloprid TC 10%,chlorfenapyr TC 10%,7227-A 2%,BC/10 0.5%,xanthan gum 0.2%,magnesium aluminium silicate 0.5%,urea 5%,defoaming agent and preservative 0.5%,and deionized water making up to 100%.All specifications of 20%imidacloprid and chlorfenapyr SC comformed to the requirements of SC and the method is feasible.
