    • PURPOSE: A herbicide composition showing a wide range of herbicidal spectrum by increasing the speed and effect of control activity through the combination of cyhalofop and metamifop is provided. The composition effectively controls Barnyardgrass and thus is useful to control grassy weeds. CONSTITUTION: A herbicide composition contains 5 to 75% by weight of cyhalofop and 15 to 95% by weight of metamifop, based on the total weight of the herbicide. The effective component of herbicides in the composition is sprayed in a concentration of 7.5 to 300g ai/ha. Grassy weeds are selected from the group consisting of Barnyardgrass, johnsongrass, Shattercane, Fall panicum, Chinese sprangletop, Bermudagrass, Large crabgrass, Green foxtail, Yellow foxtail, Jointhead arthraxon, Wild oat, Corn, Goosegrass, Eragrostis, Water foxtail, Orchardgrass, Canarygrass, Blackgrass, Jointgrass, Annual bluegrass, Japanese brome and Guackgrass.
    • 目的:提供了一种除草剂组合物,其通过提高通过组合氰氟草酯和metamifop的控制活性的速度和效果而显示广泛的除草谱。 该组合物有效控制稗草,因此可用于防治草地杂草。 构成:基于除草剂的总重量,除草剂组合物含有5-75重量%的氰氟草醚和15-95重量%的禾草属。 组合物中除草剂的有效成分以7.5-300g ai / ha的浓度喷洒。 草地杂草选自稗草,johnsongrass,Shattercane,秋季黍,中国ng藜草,狗牙根,大马唐,绿狗尾草,黄狗尾草,Jointhead arthraxon,野燕麦,玉米,鹅耳草,Eragrostis,水狐尾草,Orchardgrass,金丝雀草 ,Blackgrass,Jointgrass,年度蓝草,日本雀麦和Guickgrass。
