Abstract

The control effects of five insecticides to Plutella xylostella Linne of cruciferae vegetables were studied.The result of the experiments showed that 2% Avermectin powder ME and 5% Lambda-cyhalothrin EW possessed comparatively satisfied effect on the prevention and control of the Plutella xylostella Linne.The prevention effect was more than 82.4% after 2 d,and than 90.8% after 7 d.2.2% emamectln benzoate ME,2.2% emamectln benzoate ME and 2.5% decamethrin Ec had a good control effect against it and the prevention effect was more than 69.2% after 2 d,and than 87.8% after 7 d.
