10种杀虫剂对桃小食心虫防治效果评价

Evaluation of the effect of 10 new insecticides on the control of(Carposinasasakii Matsmura)

【目的】研究不同杀虫剂对桃小食心虫Carposina sasakii Matsmur的防治效果,筛选环境友好型农药和施药量,为有效控制桃小食心虫的发生与危害提供科学依据。【方法】选择10种新型杀虫剂2022年采用田间小区药效试验,比较不同杀虫剂的防治效果。【结果】10种处理药后7 d防效均较好,处理间无显著性差异(P>0.05),其中10%联苯·氟酰脲悬浮剂、1%苦参碱可溶液剂和12%甲维·虫螨腈悬浮剂,在药剂稀释倍数药后14 d,防效均能达到93.33%以上,1%苦参碱可溶液剂在药后21 d各所有处理区防治效果均在90.00%以上,不同药剂之间在药后14~21 d防治效果有一定波动。【结论】参试10种药剂各处理区药后7 d对桃小食心虫均具有显著的防治效果,其中1%苦参碱可溶液剂、10%联苯·氟酰脲悬浮剂和12%甲维·虫螨腈悬浮剂,施药后14 d防治效果表现优异,可在生产实践中使用。

【Objective】Study on Carposinasasakii Matsmur and screen out the environmentally friendly pesticides and application amounts in the hope of providing scientific basis for effectively controlling the occurrence and harm of Carposinasasakii Matsmur.【Methods】To clarify the control effect of 10 new insecticides.In 2022,field community efficacy tests were carried out to compare the control effects of different insecticides.【Results】The prevention effect of 10 pesticide treatment pesticides was good for 7 days,and there was no significant difference between treatments(P>0.05),among which 10%biphenyl fluranyl urea suspension,1%matrine solution and 12%methyl carboxynitrile suspension were more than 93.33%after 14 days after the recommended dilution factor,and the prevention effect of 1%matrine solution in all treatment areas was more than 90.00%21 days after applying pesticides,and the prevention and control effect fluctuated between different agents in 14-21 days after the drug.【Conclusion】The treatments of 10 agents on Carposinasasakii Matsmur have significant control effects on Carposinasasakii Matsmur for 7 days after the trial,including 1%matrine solution,10%biphenyl fluranyl urea suspension and 12%carboxylapyril suspension,which all have excellent control effect for 14 days after application,and are recommended for use in production practice.
