Abstract

The invention discloses a novel herbicide, and a preparation method and application thereof. The novel herbicide is composed of an active ingredient, a synergistic ingredient and an auxiliary ingredient, wherein the active ingredient is a composition of quinclorac, bispyribac-sodium and glufosinate; the synergistic ingredient is gamma-polyglutamic acid; and the auxiliary ingredient is a composition of one or more selected from the group consisting of a surfactant, an emulsifier, a thickener, a dispersant, an antifoaming agent and a solvent. Through compounding of the ingredients in the herbicide, the herbicidal spectrum of the herbicide is broadened, prevention and treatment effects are effectively improved, the dosage of the herbicide at the same control level is reduced, and the effective action time of the herbicide is prolonged.

Description

technical field [0001] The invention relates to the field of pesticide chemistry, in particular to a combined herbicide containing polyglutamic acid, quinclorac, bispyribac and glufosinate-ammonium, its preparation method and application. Background technique [0002] Weeds have many characteristics such as large seed setting, uneven seed maturity and emergence, multiple reproduction methods, wide transmission routes, long seed life, strong adaptability, fast growth speed, and community diversity. Weeds co-exist with crops such as corn, wheat, rice, soybeans, and yams. They not only compete for nutrients, water, sunlight, and space, reducing crop yields, but also some weeds are poisonous and can cause poisoning to humans and animals. Production has caused great harm. [0003] The use of chemical herbicides to kill weeds is the most commonly used weeding measure in agricultural production. It has the characteristics of high weeding efficiency, good weeding effect, and simple...
