Abstract

The invention discloses an herbicide composition containing metamifop and quinclorac. The herbicide composition comprises primary active ingredients and secondary active ingredients, wherein the primary active ingredients comprise the following components in parts by mass: 5-10 parts of metamifop and 10-20 parts of quinclorac; the secondary active ingredients are selected from the following components in parts by mass: 10-20 parts of cyhalofop-butyl, 3-8 parts of bispyribac-sodium, 1-6 parts of halosulfuron-methyl, 3-7 parts of pyrazosulfuron-ethyl and 6-10 parts of pyribenzoxim; and the secondary active ingredients refer to one of cyhalofop-butyl, bispyribac-sodium, halosulfuron-methyl, pyrazosulfuron-ethyl and pyribenzoxim. The invention relates to the technical field of herbicides. According to the herbicide composition containing metamifop and quinclorac disclosed by the invention, the problems such as herbicide resistant weed plants appearing, soil contamination, degradation of water, harm of non-weeds and the like are solved.

Description

technical field [0001] The invention relates to the technical field of herbicides, in particular to a herbicide composition containing fenpyramid and quinclorac. Background technique [0002] Weeds refer to plants that grow in places that are harmful to human survival and activities. They are generally non-cultivated wild plants or plants that are not harmful to humans. There are 30,000 species of weeds widely distributed in the world, and about 1,800 species cause different effects on crops every year. The degree of damage caused by weeds is as high as 9.7% per year. Herbicides refer to agents that can completely or selectively kill weeds, also known as herbicides, which are 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. ...
