Novel herbicide

Abstract

The invention discloses a novel herbicide. The novel herbicide is prepared from, by weight, 2-5 parts of biuret, 10-20 parts of sodium chlorate, 5-10 parts of 4-chloropyridine hydrochloride, 10-20 parts of trichloroacetic acid, 20-30 parts of water and 20-30 parts of ethyl alcohol. By strong acidity of 4-chloropyridine hydrochloride and trichloroacetic acid, protoplasm deterioration of weeds is realized, and quickness in weed cell death is realized; biuret makes the weeds poisoned and results in burnt seedlings and withered and yellow leaves; effect combination is realized through a water-ethanol mixed solvent, and efficient weeding is realized.

Description

technical field [0001] The invention relates to the field of herbicides, in particular to a novel herbicide. 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, and are a class of substances used to eliminate or inhibit plant growth. Commonly used herbicides are organic compounds, which can be widely used to prevent and 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 also caused a series of problems, such as the emergence...

Problems solved by technology

Over 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
