摘要
田间试验表明,乐斯本乳油(%)能有效控制小粒咖啡根粉蚧(4PIanococcodes robustus)的为害;2次施药防效为~,次施药后防效达~,药效期达以上;其平均防效显著、极显著73.6%96.4%398.1%100%30d地高于速灭杀虫乳油(%)、乐果乳油(%),敌杀死乳油()、莫需比可湿性粉剂(%)、苦50402.5%20参碱(%)和氢胺磷乳油(%)。
The result shows that chlorpyrifos 4%EC is good for control PIanococcodes robustus.The control effect is 73.6%~96.4% after two applications. The controlling effect is 98.1%~100.0% after three applications. The effective stage is over 30d.The average control effect is higher than fenitrothion 50%EC,dimethoate 40%EC,deltamethrin 2.5%EC,acetamiprid 20% WP, and matrine 36%.
