Abstract

The invention discloses a herbicide composition containing metamifop and dichloro-quinolinic acid. The herbicide composition is prepared by stirring and mashing, crushing and grinding, sampling and detecting, filtering after the product is qualified, weighing and measuring, packaging and putting into storage. A preparation method of the herbicide composition is scientific and reasonable, easy to operate, convenient for improvement of production efficiency, low in production cost, environmentally-friendly and free from pollution; the metamifop has is efficient, low in toxicity and environmentally-friendly, and is almost absorbed by stems and leaves so as have no requirement for water and be used under the condition that water exists or does not exist; the dichloro-quinolinic acid can betterremove gramineous weeds such as barnyard grass and moleplant seed; the herbicide composition is very environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical compounds, 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 weed damage is as high as 9.7% every year. Herbicides refer to agents that can completely or selectively kill weeds, also known as herbicides. 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. . [0003] However, the her...
