食用玫瑰白粉病综合防治研究

The Study on Integrated Control Techniques of Rose Powdery Mildew

为探究食用玫瑰白粉病的综合防治技术,选用农药组配、平衡施肥、修剪等综合防治措施对玫瑰白粉病进行防治研究.结果表明,通过喷施99%磷酸二氢钾700倍液对玫瑰白粉病的防效为21.86%;修剪对玫瑰白粉病的防效为34.22%;施用50%醚菌酯1 000倍液+40%嘧霉胺1 000倍液+99%磷酸二氢钾700倍液对白粉病的防效为71.70%,防治效果最佳.

In order to study the integrated control technique of rose powdery mildew,pesticide equipping,balanced fertilization, trim were tested.The results show that the control effect of the 700 times liquid of 99% monopotassium phosphate reached 21.86%;The control effect of trim reached 34.22%;the control effect of the liquid mixed with 50% kresoxim-methyl 1 000 times＋40% pyrimethanil 1 000 times ＋99% monopotassium phosphate 700 times reached 7 1.70% and can achieve the best control efficiency.
