摘  要:
在南瓜白粉病的始发期,比较3种杀菌剂对南瓜白粉病的防治效果。试验结果表明,第1次和第2次药后7天福星(40%氟硅唑乳油7500倍液)、成标(80%硫磺干悬浮剂600倍液)和15%三唑酮可湿性粉剂1000倍液的防治效果分别为95.69%,94.43%,92.74%和80.85%,73.08%,68.91%。其中,2次施药后福星的防治效果都显著高于三唑酮的,而福星和成标、成标与三唑酮之间差异均不显著。因此,这3种杀菌剂均可作为防治南瓜白粉病的有效药剂,其中福星可作为南瓜白粉病防治的首选药剂。

摘  要:
In the early stage of disease development, randomized block design was used to evaluate the control efficiency of three fungicides on pumpkin powdery mildew (Sphaerotheca fuliginea Poll.). The results after 7 days of the first and the second time showed that the control effect of the Fuxing (40% Flusilazole EC at 7 500 times dilution ), Chengbiao ( 80% Sulphur DF at 600 times dilution ), the 15% Triadimefon WP at 1 000 times dilution were 95.69%, 94.43%, 92.74%, and 80.85%, 73.08%, 68.91%, respectively. The control efficiency of Fuxing on pumpkin powdery mildew was significantly higher than that of Triadimefon, but the the control efficiency between Fuxing and Chengbiao, Chengbiao and Triadimefon had no significant difference. So, All the three fungicides could be used for controlling the pumpkin powdery mildew, but the Fuxing was the first choice.
