摘要
为了有效防治芳香木蠹蛾,将40％氧化乐果乳油稀释成不同浓度后进行树干注射,对芳香木蠹蛾进行防治试验。与对照组相比较,不同浓度药液的防治效果存在显著差异。并且在植株耐药范围内,在每次注射药量一定的前提下,随着药液浓度的增加,幼虫死亡率上升,药效期延长,防治效果更为显著。
For controlling Cossus cossus orientalis Gaede efficiently , we have a experiment on preventing of Cossus cossus orientalis Gaede,injecting the trunk with different density solution by diluting the solution of 40% Omethoate. In contrast with each other, different density has different effect obviously. Under the case of the same quality of the solution and within the drug resistance of the plant, with in-creasing the density of solution, the death rate of the worms is up, and the effectiveness of the drug becomes longer, and effect of prevention is apparent.
