Embodiment 1

[0035] Example 1: (30% glufosinate-ammonium suspension)

[0036]

[0037] The above formula is added to a conical mixer at one time in proportion to mix, crushed by a ball mill, then added to a sand mill for grinding, and mixed with high shear to prepare a 30% glufosinate suspending agent.

Embodiment 2

[0038] Example 2: (50% glufosinate-ammonium water dispersible granules)

[0039]

[0040] The above materials are added together into the conical mixer and mixed evenly, and then pulverized by the jet pulverizer. The pulverized materials are then mixed in the conical mixer. The fineness of the mixed material is 98%, which passes through a 30-mesh standard sieve and is added to the kneader. A plastic material is kneaded, and finally the material is put into an extrusion granulator for extrusion and granulation. After granulation, 50% glufosinate-ammonium water dispersible granules are obtained after drying and sieving.

Embodiment 3

[0041] Example 3: (70% glufosinate-ammonium wettable powder)

[0042]

[0043] The above materials are added together into the conical mixer and mixed evenly, and then pulverized by the jet pulverizer. The pulverized materials are then mixed in the conical mixer. The fineness of the mixed material is 98% and passes through a 600-mesh standard sieve, that is, 70% is obtained. Glufosinate-ammonium WP.

Abstract

The invention discloses a synergistic herbicidal composition and its preparation and application. The synergistic herbicidal composition consists of glufosinate-ammonium, 1,2,4-triazol-3-one, linalool and optional adjuvants. The herbicidal composition can promote the absorption and conduction of effective ingredients by weeds, so that the onset time is significantly shortened, the weeds are not easy to turn green after the onset of effects, the biological activity of glufosinate-ammonium for killing weeds is significantly improved, and at the same time resistance to weeds Grass has a good control effect. While increasing the herbicidal effect of glufosinate, it can reduce the unit dosage and use frequency of glufosinate, thereby reducing the pollution of glufosinate to the environment and slowing down the resistance of weeds to glufosinate. It is of great significance to the comprehensive management of weed resistance.

Description

technical field [0001] The present invention relates to the technical field of compound pesticide application, and more particularly to a synergistic herbicidal composition containing 1,2,4-triazol-3-one, linalool and glufosinate-ammonium, and its formulation and application. Background technique [0002] Glufosinate-ammonium is one of the most important herbicide varieties in the world. Glufosinate-ammonium is a non-selective conductive herbicide of phosphonic acid, which can inhibit the glutamine synthase in the nitrogen metabolism pathway of plants, thereby causing ammonia in plants. A large amount of accumulation leads to metabolic disorders, and at the same time, it seriously damages the photosynthesis of plants, and eventually the plants die. Glufosinate-ammonium has the characteristics of broad spectrum, low toxicity, high activity and good environmental compatibility, and its speed of exerting its activity is better than that of glyphosate. [0003] With the sharp r...
