不同除草剂与杀菌剂混用对小麦的安全性试验

为明确当地冬小麦田常用除草剂和杀菌剂混用的药效及对小麦的安全性，探索一次施药兼防兼治病虫杂草的目的, 通过设置7个除草剂与杀菌剂的混合使用，记载各处理对小麦有无药害，药害症状和程度；同时观察对小麦条锈病防治效果。结果表明，药剂混配使用有增效和扩大防治对象的作用，节省劳动力，但二甲唑草酮·双氟磺草胺和甲基二磺隆二者之间不能混配使用。

Experiment of Mixture of Different Herbicides and Fungicides to Safety of Wheat

In order to clarify the efficacy and safety of mixture of herbicides and fungicides used in local winter wheat field, and to explore one-time application of herbicides and fungicides for control of diseases and weeds, seven herbicides and fungicides were mixed to record damage to wheat, symptoms and degree. At the same time, the control effect on wheat stripe rust was observed. The results showed that the mixed use of herbicides and fungicides could increase the efficiency and enlarge the control objects, save labor. However, Dimethyl carfentrazone-ethyl ·florasulam and Mesosulfuron-methyl cannot be mixed to apply.
