Abstract

The invention discloses a herbicide composition and the application thereof. The herbicide composition is prepared by using glyphosate or salt compounds thereof, and fluroxypyr or ester compound thereof as effective ingredients, wherein the weight part ratio of the glyphosate or salt compounds thereof to the fluroxypyr or ester compound thereof is (1:1) to (50:1), preferably (8:1) to (30:1). The total weight of the effective ingredients accounts for 10 to 90 percent of the weight of the composition, and the herbicide composition is used for preventing and extirpating weeds in uncultivated areas, orchards and corn fields. Compared with single agents, the herbicide composition disclosed by the invention has the advantages of obviously improving the control efficiency, reducing the dosage of pesticides, reducing the adverse impacts of the pesticides on the ecological environment, having great significance in the comprehensive treatment on the herbicide resistance of weeds, and having huge economic benefits and social benefits.

Description

technical field [0001] The invention relates to an agricultural herbicide composition, which uses glyphosate or its salt compound, fluroxyfen or its ester compound as active ingredients, and is used for preventing weeds in non-cultivated land, orchards and cornfields. Background technique [0002] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance. At the same time, when weeds occur, the grass phase is complex, not only annual and perennial weeds are mixed, herbs, vines and shrubs are mixed, but also the emergence of weeds is uneven, and the seeds, young and old weeds are staggered, so the herbicide species alone When used, all will show some defects and limitations. [0003] Glyphosate is one of the most widely used herbicides in the world. It is a herbicide that kills and is known for its strong systemic conductivity. Through c...
