This experiment was carried out to explore the effects of microbial pesticides on prevention and control of cucumber downy mildew.Three kinds of microbial pesticides( Recharge,Dynamic F,and 3. 0% amino-oligosaccharin AS) were used and clean water was taken as the control( CK). The experiment showed that Recharge and 3. 0% amino-oligosaccharin AS had better control effect on cucumber downy mildew.After the first application,the average control effect of Recharge and 3. 0% amino-oligosaccharin AS was higher than 50%. After the third application,the average control effect of Recharge and 3. 0% amino-oligosaccharin AS was higher than 20%. The control effect of Dynamic F on cucumber downy mildew was relatively poor,and the average control effect after the first application was 38. 34%,and the average control effect after the third application was only 15. 64%. According to the experimental results,the average control effect of three pesticides after application showed a gradual decline trend.
