Abstract
In 2009,the control effects of three pesticides,50% Kresoxim dry suspension,25% B-ethyl phenol suspension,difenoconazole on hot pepper powdery mildew were studied.The results showed that these pesticides had significant ef-fects on controlling hot pepper powdery mildew.The B-ethyl phenol 500× and 600× had the longest controlling time of 10 days with 80% controlling rate.Meanwhile,the other pesticides also had controlling rate of 70.77%-77.57%.
