Problems solved by technology

[0004] At present, the preparations of glufosinate-ammonium in the market are mainly water and soluble liquids, which have high packaging and transportation costs, inconvenient use and measurement, and poor drug efficacy. There are still many quality problems, such as: flocculation, Crystallization, intolerance to storage, easy to decompose, etc.

preparation example Construction

[0039] The present application has no special limitation on the preparation method of the glufosinate-ammonium water-soluble granule, and it can be prepared in a manner well known to those skilled in the art. Exemplary, the preparation method of the glufosinate-ammonium water-soluble granule is specifically:

[0040] Mix glufosinate-ammonium, surfactant and filler to obtain the first product, or mix glufosinate-ammonium, surfactant, chelating agent, synergist and filler to obtain the first product;

[0041] The first product is mixed with water, then extruded, granulated and dried in sequence to obtain the glufosinate-ammonium water-soluble granule.

[0042] In the above process, the extrusion granulation and the drying are technical means well known to those skilled in the art, and there is no particular limitation in this application.

[0043] In the above process, the mass of the water is 3%-6% of the mass of the first product, and the drying temperature is preferably 40-9...

Abstract

The present invention provides a glufosinate ammonium water-soluble granule, which comprises glufosinate ammonium, a surfactant and a carrier, wherein the glufosinate ammonium water-soluble granule further comprises a chelating agent and a synergist. According to the present invention, the type of the auxiliary agent of the glufosinate ammonium water-soluble granule is regulated, and the proper auxiliary material is combined and supplemented, such that various components synergistically act so as to obtain the glufosinate ammonium pesticide capable of achieving excellent water solubility, excellent dissolution stability, low foaming property and efficacy in high-concentration hard water, wherein the obtained glufosinate ammonium pesticide is especially suitable for countries and regions with high water hardness.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a water-soluble glufosinate-ammonium granule. Background technique [0002] Glufosinate-ammonium (glufosinate-ammonium) is an organophosphorus non-conductive herbicide targeting glutamine synthetase (GS). It is a broad-spectrum contact herbicide with weak systemic effect. Phosphate kills roots differently. Glufosinate-ammonium kills leaves first, and can conduct transpiration in plant xylem through plant transpiration. Its quick-acting effect is between paraquat and glyphosate. At the same time, glufosinate-ammonium is a non-conductive herbicide with high efficiency, low toxicity, and environmental friendliness. It is easy to degrade in the soil, safe for crops, not easy to drift, has a wide weeding spectrum, high activity, and low dosage. , the environmental pressure is small, and it is the world's largest tonnage pesticide variety. However, environmental factors such as li...
