[目的]探究36%多·酮悬浮剂对小麦田白粉病和赤霉病的防治效果。[方法]通过田间试验研究了36%多·酮悬浮剂对小麦白粉病和赤霉病、油菜菌核病的防治效果及对油菜产量的影响。[结果]当36%多·酮悬浮剂施药量为2 250 ml/hm2时,药后7、14 d对小麦白粉病和赤霉病、油菜菌核病的防效均最佳,同时使油菜产量提高了32.00%。[结论]为36%多·酮悬浮剂的进一步开发推广提供了理论依据。
[Objective] The research aimed to investigate the control effect of 36% multi-ketone suspending agent on powdery mildew and scab in wheat field. [Method] The control effect of 36% multi-keton suspending agent on wheat powdery mildew and scab, Sclerotinia sclerotiorum and its effect on the yield of rape were studied in field experiments. [Result] When the dosage of 36% multi-keton suspension was 2 250 ml / hm2, the control effect on wheat powdery mildew and scab, Sclerotinia sclerotinis was best at 7 and 14 days after treatment, Rape production increased by 32.00%. [Conclusion] This provided a theoretical basis for the further development and promotion of 36% polyketone suspending agent.
