Glyphosate-containing weeding composition

Abstract

The invention provides a glyphosate-containing weeding composition. The composition contains active ingredients of glyphosate or salts thereof, 2-methyl-4-chlorophenoxy acetic acid or salts or esters thereof and fluroxypyr or salts or esters thereof at the same time. The weeding composition mainly comprises the following active ingredients in parts by weight: 30-80 parts of glyphosate or salts thereof, 2-20 parts of 2-methyl-4-chlorophenoxy acetic acid or salts or esters thereof, 1-20 parts of fluroxypyr or salts or esters thereof and the balance of non-weeding composition ingredients. Ranges are preferably as follows: 30-60 parts of glyphosate or salts thereof, 2-16 parts of 2-methyl-4-chlorophenoxy acetic acid or salts or esters thereof, 1-16 parts of fluroxypyr or salts or esters thereof and the balance of non-weeding composition ingredients. Better ranges are preferably as follows: 50-60 parts of glyphosate or salts thereof, 4-8 parts of 2-methyl-4-chlorophenoxy acetic acid or salts or esters thereof, 3-6 parts of fluroxypyr or salts or esters thereof and the balance of non-weeding composition ingredients. The composition can be prepared into liquid, emulsion, microemulsion, wettable powder, water dispersible granules, effervescent tablets and effervescent granules, and is used for preventing and weeding annual and perennial weeds of uncultivated areas, eucalyptus forests and citrus reticulata blanco orchards.

Description

technical field [0001] The invention relates to an agricultural compound herbicide composition, in particular to a composition of three active ingredients, glyphosate, 2-methyl-4-chlorophenoxyacetic acid and fluroxypyr, and belongs to the technical field of pesticides . Background technique [0002] Glyphosate is a systemic chronic broad-spectrum herbicide that mainly inhibits enolacetonyl shikimelin phosphate synthase in the body, thereby inhibiting the conversion of shikime to phenylalanine, tyrosine and tryptophan. Transformation, which interferes with protein synthesis leading to plant death. Glyphosate is absorbed by the stems and leaves and then transmitted to various parts of the plant. It can control more than 40 families of plants such as monocots and dicotyledons, annuals and perennials, herbs and shrubs. Glyphosate soon combines with metal ions such as iron and aluminum to lose its activity after entering the soil. It has no adverse effects on the seeds and soil...

Problems solved by technology

[0014] The main purpose of the present invention is to provide a solution for the deficiency that a single dose of glyphosate cannot prevent and control some malignant weeds such as Miscanthus, and the existing mixed preparations containing glyphosate cannot effectively prevent and control malignant weeds such as Miscanthus. ternary compound herbicide
