不同药剂对麦田看麦娘属(Alopecurus)杂草的防除效果

The Efficacy of Different Herbicides in Controlling Weeds in the Genus Alopecurus in Winter Wheat Fields

本文比较了异丙隆、炔草酯、甲基二磺隆等不同药剂对小麦田看麦娘属(Alopeeurus)杂草的防除效果。结果表明:3%甲基二磺隆OD 20 mL/667 m^2、5%唑啉草酯EC 80 mL/667 m^2、8%炔草酯EW 60 mL/667 m2和7.5%啶磺草胺WG 15 g/667 m^2均可高效防除冬小麦田看麦娘属杂草;冬前施药50%异丙隆WP 250 g/667 m^2防效明显好于春后施药。建议防除冬小麦田看麦娘属杂草尽量选择冬前施药,药剂可选择50%异丙隆WP单用或与其他不同类型的除草剂混用,用量推荐50%异丙隆WP 150~200 g/667 m^2。

This study compared the efficacy of different herbicides in controlling gramineous weeds in wheat fields,which included isoproturon,Clodinafop-propargyl,and Mesosulfuron-methyl.The results showed that treatments Mesosulfuron-methyl（3% OD）applied at the rate of 20 mL/667 m^2,pinoxaden（5% EC） at 80 mL/667 m^2,Clodinafop-propargyl（8% EW） at 60 mL/667 m^2,and pyroxsulam（7.5% WG） at 15 g/667 m^2 all effectively controlled gramineous weeds.Moreover,application of isoproturon（50 WP） at the rate of 250 g/667 m^2 before winter achieved a higher level of control efficacy than its application in the spring.Therefore,we suggest that herbicides should be applied to winter wheat fields before winter to control gramineous weeds.Regarding the types of herbicides,we recommend using isoproturon alone or in combination with other types of herbicides.With respect to its application rate,we recommend application of isoproturon（50%WP） at 150 to 200 g/667 m^2.
