Research of Fungicide Control to Powdery Mildew in Greenhouse Hot Pepper

The fungicide control experiment were studied in the fields.The results showed that all the tested fungicides could control the powdery mildew of greenhouse hot pepper,among them 15% triadimefon 1 000 times liquid + 77% cocide 1 200 times liquid had the best control effect,40% nustar 6 000 times liquid took second place,and 50% stroby 3 000 times liquid had disease to hot pepper.So aerial spray of 15% triadimefon 1 000 times liquid + 77% cocide 1 200 times liquid at the early stage of powdery mildew,fungicide used 2 or 3,and the time interval was 7 or 10 days was recommended.The effects of alternative use of 40% nustar 6 000 times and 15% triadimefon 1 000 times liquid + 77% cocide 1 200 times liquid was better when the powdery mildew occurred seriously.
