Weed killer

Abstract

The invention discloses a weed killer. The weed killer is prepared from 2-amino-3-chlorobenzoate methyl ester, bensulfuron methyl, 2,3-difluoro-5-chloropyridine and 2-chloro-4-diethylin-6-isopropamide-1,3,5-triazine, acetochlor emulsifiable concentrate and atrazine. The weed killer is prepared by compounding a plurality of weed-killing chemical preparations, and has the advantages of stable property, good weed killing effect, small dosage, and no pollution on soil after compounding; the use effect of the weed killer is not influenced by the limits of the types of crops and weeds. The weed killer is suitable for killing weeds.

Description

Technical field [0001] The invention belongs to the field of pesticide pharmacy and relates to a herbicide. Background technique [0002] At present, in agricultural planting, there are 30,000 species of weeds widely distributed in the world, and about 1,800 species of weeds cause varying degrees of damage to crops each year. The annual crop yield due to weed damage is as high as 9.7%. Herbicides are agents that can kill weeds completely or selectively. They are also known as herbicides. They are used to destroy or inhibit the growth of plants. [0003] Commonly used herbicides are organic compounds, which can be widely used to control weeds, shrubs, trees and other harmful plants in farmland, orchards, flower nurseries, grasslands and non-cultivated land, railway lines, rivers, reservoirs, warehouses and other places. 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, suc...

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.

[0004] Most of the herbicides currently used are mostly kill-type or contact-type herbicides. The herbicide effect is limited by the types of crops and weeds, which greatly affects the herbicide effect. The existing herbicides are used in large quantities, which not only causes waste and easily pollute the soil, causing secondary hazards
