- 摘要:
- 以新型药剂50%苯醚甲环唑?硫磺水分散粒剂为试材，采用常规喷雾法，研究了对西瓜白粉病的田间防治效果。结果表明：最有效浓度为每667 m2施用50%苯醚甲环唑?硫磺水分散粒剂80 g，第2次药后7 d对西瓜白粉病的防治效果达70.81%，第4次药后7 d的防治效果为83.28%。防效均高于对照药剂250 g?L-1苯醚甲环唑乳油和80%硫磺水分散粒剂。生产上可以将50%苯醚甲环唑?硫磺水分散粒剂稀释900~1 200倍使用。
- Abstract:
- The effect of spraying 50% difenoconazole-sulfur water dispersible granule against watermelon powdery mildew was studied by spraying method.The results showed the best amount of 50% difenoconazole-sulfur water dispersible granule was 80 g per 667 m2.Seven days after the second spraying，the control effect reached 70.81%，and it reached 83.28% seven days after the fourth spraying.The control effect were more significant than that of 250 g?L-1 of difenoconazole EC and 80% sulfur WG.Therefore, it was suggested to dilute 50% difenoconazole-sulfur water dispersible granule to 900-1 200 times before use.
