应用多种生物制剂防治美国白蛾研究初报

Preliminary Report on the Control of Hyphantria cunea with Multiple Biologicals

本文研究了多种生物制剂混配对美国白蛾的防治效果。结果显示,10亿PIB/mL甘蓝夜蛾核型多角体病毒悬浮剂与20%除虫脲悬浮剂、5%环虫酰肼悬浮剂混配具有明显的增效作用;10亿PIB/mL甘蓝夜蛾核型多角体病毒悬浮剂与8000IU/μL苏云金杆菌悬浮剂混配使用效果一般;25亿PIB/mL美国白蛾核型多角体病毒悬浮剂混配5%环虫酰肼悬浮剂效果较差。

In this paper,a study was made on the effects of mixed multiple biologicals on controlling Hyphantria cunea.The results showed that the mixed MabrNPV 1 billion PIB/mL SC,diflubenzuron 20%SC and chromafenozide 5%SC had a significant synergistic effect;the mixed MabrNPV 1 billion PIB/mL SC and BT 8000 IU/μL SC had a general effect;the mixed hyphantria cunea NPV 2.5 billion PIB/ml SC and chromafenozide 5%SC had a poor effect.
