摘要
采用玻片浸渍法进行了病虫净复配剂对油菜蚜虫的室内毒力测定。测定结果表明 :病虫净复配剂的毒力均大于各单剂。复配剂Ⅰ、Ⅱ的共毒系数分别为 2 0 4 13和 15 3 2 9,均大于 10 0 ,表现增效 ,复配剂Ⅲ ,Ⅳ的活性系数分别为 2 5 6和 1 78,均大于 1,也表现为增效 ,证明病虫净是防治油菜蚜虫的理想复配药剂。
Toxicity of BCJ was determined by slide dipmethod applied on rape aphis in indoors.Determined result shows:the toxicity of BCJ was more powerful than other single formulation. coefficients if co toxicity of complex formulation Ⅰand Ⅱ were 204.13 and 153.29 respectively.Both were more over 100.Coefficients of activity of complex formulation Ⅲ,Ⅳ were 2.56 and 1.78 respectively,both were more over 1.Effect display of trapping were synergizedaction BCJ were proved effective to control rape aphis.
