70%氟唑磺隆WDG防除冬小麦田杂草的药效

Effects of 70% Flucarbazone WDG on Controlling Weeds in Winter Wheat Field

[目的]研究了氟唑磺隆及其复配剂对冬小麦田杂草的效果。[方法]调查了氟唑磺隆及其复配剂使用的安全性和防效。[结果]70%氟唑磺隆WDG 45.0和52.5 g/hm2对小麦田禾本科杂草的防效较差,对阔叶草无效;氟唑磺隆和苯磺隆、二甲四氯铵盐复配,可以提高对小麦田阔叶杂草生长的控制效果,但降低了氟唑磺隆对禾本科杂草的控制效果。[结论]在试验期间,未发现氟唑磺隆及其复配剂对冬小麦有药害,氟唑磺隆对冬小麦安全。

[ Objective ] The research aimed to study the effect of flucarbazone and compounded agents on controlling weeds in winter wheat field. [ Method] The security and control effect of flucarbazone and compounded agents were investigated. [Result] 70% flucarbazone of 45.0,52.5 g/hm^2 had poor control effect on grass in wheat field,and had no effect on broad-leaf grass. Compounded agents of flucarbazone and tribenuron-methyl,MCPA could improve the control effects on broad-leaf grass, but decrease the control effects on grass. [Conclusion] During the period of the experiment, phytotoxieity of fluearbazone and corrrpounded agents was not found in winter wheat field. So fluearbazene was safe for winter wheat.
