【Abstract】 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%.
