Abstract
The field drug-efficiency experiments of three kinds of fungicides（43% tebuconazole SC,0.5% physcion agent,75% trifloxystrobin· tebuconazole WG） on cream pumpkin powdery mildew disease were carried out.The results showed that 400-times diluent of 43% tebuconazole SC had a better control efficiency and longer effective period,followed by 5000-times diluent of 75% trifloxystrobin· tebuconazole WG,which had comprehensive action effects of trifloxystrobin and tebuconazole,a broad spectrum of disease control and longer effective period.However,250-times diluent of 0.5% physcion agent had lower control efficiency.But it also had potential application prospects,for it was botanical microbicides and was more safety than chemical fungicide.关键词
