Screening of Chemical Pesticides for Control of Leptocybe invasa
摘要
Abstract
To seek for the effective pesticides controlling Leptocybe invasa,we select seven commonly used pesticides and three kinds of mixture to do field efficacy test,the results showed that 10 groups of selected pesticides had control effect of different degrees on L. invasa. Except chlorpyrifos,the number of galls at 30 d after applying pesticide and the number of emergence holes at 40 d after applying pesticide in other pesticide treatments showed significant difference from the blank control. On the basis of galls and emer-gence holes decrease rates as indexes,16% Chongxianqing EC was an ideal pesticide for controlling L. in-vasa. The galls decrease rate was 83. 37% at 30 d after applying pesticide,and the emergence holes de-crease rate was 83. 57% at 40 d after applying pesticide. And if it is mixed with 2. 5% efficient cyhalo-thrin EC,the control effect will be more pronounced. This shows that mixed using of different mechanisms of insecticides has obvious synergism.关键词
