摘  要:
进行43%戊唑醇悬浮剂、0.5%大黄素甲醚水剂、75%肟菌.戊唑醇水分散粒剂3种药剂防治奶油南瓜白粉病的田间药效试验,结果表明:43%戊唑醇悬浮剂4 000倍液的防效较好,且持效期较长;其次为75%肟菌.戊唑醇水分散粒剂5 000倍液,具有戊唑醇与肟菌酯的综合作用机理、杀菌谱广的特点,持效期也较长;0.5%大黄素甲醚水剂250倍液的防效较低,但其为植物源杀菌剂,产品安全性较化学农药高,也具有应用推广前景。

摘  要:
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.
