Abstract
Powdery mildew is a main leaf-disease in cucumbercultivation which serious damage to the production.Fungicide application is an effective measure in controlling the disease at present.In order to determine the control effects and optimal dosage of Kersoxim-Methyl WP on cucumber powdery mildew,its control effects were tested in 2010~2011.The results showed that the control efficiency of Kersoxim-Methyl WP on cucumber powdery mildew was 66.7%~88.6%,with no phytotoxicity to cucumber,which indicated Kersoxim-Methyl could be applied to control of cucumber powdery midew.
