6%乙基多杀菌素和苏云金杆菌复配防治小菜蛾田间药效评价

Field control efficacy of mixed 6% spinetoram and bacillus thuringiensis on diamondback moth

摘要: 进行6%乙基多杀菌素和苏云金杆菌复配防治小菜蛾的田间药效试验，结果表明：每667 m²使用6%乙基多杀菌素悬浮剂30 mL加32 000 IU/mg苏云金杆菌可湿性粉剂复配两种剂量的处理防治小菜蛾的速效性和持效性均优于单独使用6%乙基多杀菌素悬浮剂30 mL的处理；持效性优于单独使用6%乙基多杀菌素悬浮剂45 mL的处理；安全性好，生产上可推广应用于防治小菜蛾，每667 m²推荐使用剂量为6%乙基多杀菌素悬浮剂30 mL加32 000 IU/mg苏云金杆菌可湿性粉剂30~45 g。

Abstract: Field efficacy trials of mixed 6% spinetoram and bacillus thuringiensis on diamondback month were conducted. The results showed that the contorl velocity and persistence of mixed 6% spintoram SC and 32 000 IU/mg bacillus thuringiensis WP on diamondback moth per 667 m² was better than that of applying 30 mL 6% spintoram SC alone, and the control persistence was better than that of applying 45 mL 6% spintoram SC alone; Meanwhile, the mixed system was proved safe in controlling diamondback moth in field production. Mixed 30 mL 6% spintoram SC and 30-45 g 32 000 IU/mg bacillus thuringiensis WP per 667 m² was recommeded.
