3种药剂防治松梢螟药效试验

Control Effect of Fhree Kinds of Pesticides on Pine Borer L.

选用不同浓度的3%高渗苯氧威、5%阿维菌素乳油、48%噻虫啉悬浮剂对越冬代松梢螟幼虫进行药剂喷洒试验。试验结果表明:施用7d后48%噻虫啉悬浮剂1000倍液、48%噻虫啉悬浮剂2000倍液、5%阿维菌素乳油1000倍液、5%阿维菌素乳油2000倍液、3%高渗苯氧威1000倍液的防效均在90%以上,考虑到防治成本和环境安全因素,选用48%噻虫啉悬浮剂2000倍液、5%阿维菌素乳油2000倍液、3%高渗苯氧威1000倍液防治松梢螟。

Different concentrations of 3%Fenoxycarb,5%Abamectin Ec and 48%Thiazoline Sc were used to spray the larvae of the overwintering larval Pine Moth.The results showed that the control effect of 48%Thiazoline Sc 1000 times solution,48%Thiazoline Sc 2000 times solution,5%Avermectin 1000 times solution,5%Avermectin 2000 times solution and 3%fenoxycarb 1000 times solution was above 90%for 7 days,considering the cost of control and environmental safety factors,48%Thiazoline Sc 2000 times solution,5%Avermectin 2000 times solution and 3%fenoxycarb 1000 times solution were selected to control pine moth.
