Haloxyfop-r-methyl-containing herbicide composition

Abstract

The invention discloses a haloxyfop-r-methyl-containing herbicide composition. The haloxyfop-r-methyl-containing herbicide composition is utilized for controlling gramineous weeds, broad-leaved weeds and sedge weeds in broad-leaved crop fields. The haloxyfop-r-methyl-containing herbicide composition comprises active components of 1, a compound A, wherein the compound A is haloxyfop-r-methyl, and 2, a herbicide mixed synergistic active component B, wherein the herbicide mixed synergistic active component B is one or more of diphenyl ether herbicides, sulfonylurea herbicides or benzothiazine dione herbicides. A weight ratio of haloxyfop-r-methyl to the herbicide mixed synergistic active component B is (1 to 30%): (0.5 to 50%). The haloxyfop-r-methyl-containing herbicide composition can be processed into all realizable dosage forms. The haloxyfop-r-methyl-containing herbicide composition can be widely utilized for controlling gramineous weeds such as barnyard grass, green bristlegrass, alopecurus aequalis, crabgrass, annual bluegrass and moleplant seed, broad-leaved weeds such as purslane, solanum nigrum, cocklebur, bindweed, chenopodium album and goosegrass herb, and sedge weeds in soybean and peanut fields, wherein the broad-leaved weeds are difficult to be controlled. The haloxyfop-r-methyl-containing herbicide composition has the characteristics of wide weed control spectrum, safety on crops, and high efficiency.

Description

technical field [0001] The present invention relates to an improved herbicide composition with expanded herbicidal spectrum, in particular to a composition herbicide containing valprodox and used for controlling grasses and broad-leaved weeds in broad-leaved crop fields . Background technique [0002] High-efficiency haloxyfop, the trade name is high-efficiency capgrass, English name: haloxyfop-R-methyl, is an aryloxyphenoxypropionic acid herbicide for post-emergence stem and leaf treatment. The leaves of weeds are absorbed, transmitted to the whole plant, accumulated in the plant meristem, inhibiting the acetyl-CoA carboxylase in the plant, resulting in the blockage of fatty acid synthesis and killing weeds. The chemicals sprayed into the soil are easily absorbed by the roots and can also kill weeds. It has a good control effect on annual and perennial grass weeds from emergence to tillering and early heading, and is used for the control of broad-leaved crops such as soyb...

AI Technical Summary

Problems solved by technology

It is used to control sedge weeds and broad-leaved weeds. It is effective against perennial weeds such as spinach and lettuce, but not effective against gramineous weeds.
