Glyphosate herbicide applicable to weeds in vegetable fields and preparation method of glyphosate herbicide

Abstract

The invention discloses a glyphosate herbicide applicable to weeds in vegetable fields. The glyphosate herbicide comprises, by weight, 35-40 parts of gyphosate solutions, 3-5 parts of hyoscyamine, 1-4parts of coumarin, 2-4 parts of szechwan Chinaberry fruit extract, 2-4 parts of radix bupleuri extract, 1-3 parts of rhizoma anemarrhenae extract, 5-10 parts of cylindrosporium phalaenopsidis sawada,1-5 parts of synergists, 3-7 parts of fumed silica, 4-6 parts of rosemary oil, 3-5 parts of dispersing agents, 3-7 parts of diatomite, 2-8 parts of carboxymethylcellulose and 40-55 parts of deionizedwater. The glyphosate herbicide has the advantages that obvious spread-spectrum synergism, high safety and high herbicidal activity are achieved, majority of gramineous weeds and broad-leaf weeds canbe killed, and the weeding effect is enhanced; the herbicide can be degraded easily in crops, safety is high, side effects are avoided, and environment pollution is small; the preparation method is reasonable, operation is facilitated, production cycle is short, energy consumption is low, quality stability is high, and the glyphosate herbicide is easy to popularize and apply.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a glyphosate herbicide suitable for vegetable field weeds and a preparation method thereof. Background technique [0002] There are 30,000 species of weeds widely distributed in the world, and about 1,800 species cause damage to crops to varying degrees every year, and the annual crop yield reduction due to weed damage is as high as 9.7%. Herbicides refer to agents that can completely or selectively kill weeds, also known as herbicides, a class of substances used to eliminate or inhibit plant growth. Commonly used herbicides are organic compounds, which can be widely used to control harmful plants such as weeds, shrubs, and trees in farmland, orchards, flower nurseries, grasslands and non-cultivated land, railway lines, rivers, reservoirs, warehouses, etc. Over the past century, herbicides have been used to effectively control many weeds, but the extensive use of chemical agents has a...

AI Technical Summary

Problems solved by technology

In the past century, herbicides have been used to effectively control many weeds, but the extensive use of chemical agents has also caused a series of problems, such as the emergence of herbicide-resistant weed plants, soil pollution, water quality degradation, and the use of non-weeds. Hazards of grass organisms (especially humans and animals), etc.

[0003] Most of the high-efficiency herbicides currently used for weeds in vegetable fields are mostly kill-type or contact-type herbicides, and the herbicide effect is limited by the types of crops and weeds, which greatly affects the weeding effect
