Problems solved by technology

[0002] Fluthiacet-methyl, chemical name: [[2-chloro-4-fluoro-5-[(tetrahydro-3-oxo-1H,3H-[1,3,4]thiadiazolo[3 , 4, α] pyridazin-1-yl) amino] phenyl] sulfur] methyl acetate, is a broad-leaved weed herbicide, the herbicide can be used in cornfields, soybean fields to control certain annual broadleaf weeds Grass, its herbicidal spectrum is limited, and the control effect on gramineous weeds such as barnyardgrass, foxtail, crabgrass, etc. is not ideal
In addition, there is no herbicide composition composed of mezinoxamic acid and other specific compounds in domestic and foreign patents, so the effect of its mixed use with other compounds is unpredictable

Abstract

A herbiciding composition contains KIH 9201 and herbicide in Wt ratio of 1:(0.1-200). The said herbicide has one or two kinds chosen from 11 herbicides such as quizalofop, fluazifop, haloxyfop, sethoxydim, etc.. It may be made into powder, suspension, or emulsified oil. Its advantages are high preventing effect, simple method of the preparation, and low cost.

Description

(1) Technical field [0001] The invention relates to a farmland herbicide, especially a herbicide composition for controlling farmland monocot and dicotyledonous weeds. (2) Background technology [0002] Fluthiacet-methyl, chemical name: [[2-chloro-4-fluoro-5-[(tetrahydro-3-oxo-1H,3H-[1,3,4]thiadiazolo[3 , 4, α] pyridazin-1-yl) amino] phenyl] sulfur] methyl acetate, is a broad-leaved weed herbicide, the herbicide can be used in cornfields, soybean fields to control certain annual broadleaf weeds Grass, its herbicidal spectrum is limited, and the control effect on gramineous weeds such as barnyardgrass, foxtail, crabgrass, etc. is not ideal. In addition, domestic and foreign patents do not have any herbicide composition composed of methazalic acid and other specific compounds, so the effect of its mixed use with other compounds is unpredictable. (3) Contents of the invention [0003] The technical problem to be solved by the invention is to expand the herbicide's herbicida...
