[Objective] The study discussed the indoor activity and field control effect of vegetable oil on cucumber powdery mildew.[Method] The cucumber seedlings of Changchunmici were adopted as the material,which were inoculated with the fungus pathogen of cucumber powdery mildew naturally occurred in the field.The indoor protective test and field test were performed respectively to observe the control effects of different plant oils EC on the cucumber powdery mildew.[Result] When six plant oils EC including cottonseed oil,soybean oil,canola oil,corn oil,sesame oil and sunflower oil was diluted into 10 and 5 ml/L,they had better control effect on cucumber powdery mildew.As for the indoor protective effect,the protective effect of the vegetable oil EC was equivalent to the control agent triadimefon EC,the field control effect of vegetable oil EC was in the range of 60%-75%,which was consistent with 69%-70% control effect of contrast agent with 1 ml/L triadimefon EC dilution.[Conclusion] All vegetable oils EC had significant control effect on cucumber powdery mildew in the test.
