Herbicide

Abstract

The invention provides a herbicide, which concretely comprises the following components in mass percent: 30%-80% of phosphonomethyl imino acetic acid, 0.5%-20% of fluoroglycofen-ethyl, 1%-10% of fluroxypyr-mepthyl, 3%-20% of surfactant, and the balance of carriers or accessories. According to the invention, the herbicide has stable properties and a reasonable formula; and the herbicide containing 40%-90% of effective components including wettable powder (WP), suspension concentrate (SC), oil deflocculant (OD), water-dispersible granules (WDG) and emulsifiable powder (WEP) can be prepared by production methods of common pesticide preparations. The herbicide provided by the invention can be used for preventing and eradicating weeds in forest lands, non-tillage fields and wastelands, and has an excellent control effect on weeds with resistance to phosphonomethyl imino acetic acid.

Description

Technical field [0001] The invention involves a composition of a chemical agent, which specifically involves a herbicide. Background technique [0002] Green oligurp is a high -efficiency, low toxic, low -residue wide -spectrum exterior herbicide, but due to the long -term use of grass glyphosate, some weeds have obvious resistance, and some perennial malignant weeds are used.Decreased, the phenomenon of incomplete grass killing, not killing the roots, or taking the medicine for a period of time, which increases the amount and use of the unit area of the glyphosate, increased the cost of use at the same time, and the multiple reuse of multiple times has also increased.The risk of the residue of glyphosate in the crops is not in line with the guidelines for the use of pesticides and the development of agricultural development. At present, domestic use of glyphosate or binary complex composition is used to increase the forest land, increase the forest land,Weeds such as non -cultiv...

AI Technical Summary

Problems solved by technology

[0002] Glyphosate is a high-efficiency, low-toxicity, low-residue broad-spectrum herbicide, but due to the long-term use of glyphosate single agent, some weeds have obvious resistance, and the control effect on some perennial vicious weeds It is common that weeds are not completely killed, the roots are not killed, or the weeds turn green and survive after a period of time, which increases the amount of glyphosate used per unit area and the number of times of use, and the cost of use increases at the same time. Repeated use also increases The risk of glyphosate residues in crops is very inconsistent with the guidelines for the use of pesticides and is not conducive to the development of agriculture; at present, glyphosate-based single-dose or binary compound compositions are used in China to increase the impact on forest land, Weed control effect on non-cultivated land, etc., there are problems such as low active ingredient, large amount of use, high transportation cost, etc.
