摘要:
通过毒力试验、表面活性剂的筛选,确定了2%阿维•绿僵菌素悬浮剂的配方,并进行了质量稳定性和田间药效研究。质量稳定性实验结果表明了2%阿维•绿僵菌素悬浮剂的各项性能稳定。田间试验结果表明,2%阿维•绿僵菌素悬浮剂以有效成分9-11 (ai) g/hm2防治甘蓝小菜蛾,防效可达75.84%~ 93.40%,明显优于1.8%阿维菌素乳油(14(ai) g/hm2)的同期防效,持效期达14天。

Abstract: The preparation and field efficacy of abamection•destruxin A 2% SC were studied in this paper. According to the laboratory bioassay, there was an obvious synergism effect on Plutella xylostella (L.) mortality, by means of tests of virulence and surface active agents, the formulation of abamection•destruxin A 2% SC was determined. The results of experimental verification of the formulated product demonstrated that all indexes of abamectiondestruxin A 2% SC confirmed to the quality technical standards. Field control efficacy of abamectiondestruxin A 2% SC (9 g/hm2 to 11 g/hm2) against Plutella xylostella (L.) in 14 days of application could reach to 75.84% - 93.40%, which was superior to the efficacy of abamection 1.8% EC (14(ai) g/hm2), and the efficacy could last for 14 days.
