- 摘要:
- 以籽用西瓜“红小片”为试材，研究比较了10%苯醚菌酯悬浮剂和250 g/L己唑醇悬浮剂施药后7和14 d对籽瓜白粉病的防治效果。结果表明：药后14 d总体比药后7 d效果好，且以药后14 d使用10%苯醚菌酯悬浮剂1 500倍液防治籽瓜白粉病防治效果最高，达到了93.90%，其次为2 000倍液，防效达到了90.68%，且2个处理间在0.1置信度内达到了差异显著；药后7 d，使用10%苯醚菌酯悬浮剂1 500倍液防治籽瓜白粉病防治效果也达到了84.61%。已唑醇和苯醚菌酯相比，其药效较差，在药后14 d，防治效果也仅为61.68%。使用10%苯醚菌酯悬浮剂还具有一定的增产效果，其中，以10%苯醚菌酯悬浮剂1 500倍液增产最高，增产率达54.20%，而250 g/L己唑醇悬浮剂的增产率仅为1.58%。
- Abstract:
- Taking the seeds of “Hongxiaopian” watermelon as the material,10% ZJ0712 SC was selected to prevent watermelon powdery mildew，compared with 250 g/L hexaconazole SC，and the disease index and control effect by 7 or 14 days after application were investigated.The results showed that the drug 14 days after overall than seven days after the drug efficacy was better，and 14 days after treatment，the control effect of 10% ZJ0712 SC 1 500 times was the highest，with its control efficiency 93.90%，followed by 2 000 times，the control efficiency of 90.68%，and two processing within 0.1 degree of confidence in a significant difference；7 days after treatment，the control effect of 10% ZJ0712 SC 1 500 times also reached 84.61%.Hexaconazole SC has been compared to alcohol and 10% ZJ0712 SC its efficacy was poor，14 days after treatment，the control effect was only 61.68%.10% ZJ0712 SC 1 500 times also had the highest yield of 54.20%，250 g/L suspension concentrate hexaconazole yield was only 1.58%.
