Ammonium glyphosate soluble granule auxiliary and preparation method thereof

Abstract

The invention discloses an ammonium glyphosate soluble granule auxiliary, which consists of the following components in parts by weight: 700 to 800 parts of ammonium glyphosate, 50 to 100 parts of ammonium sulfate, 100 to 120 parts of auxiliaries and 6 to 15 parts of water. A preparation method comprises the following technical steps: (1) adding the ammonium glyphosate and the ammonium sulfate into a mixer for mixing in the ratio; (2) crushing the uniformly mixed materials by a crusher, slowly and uniformly adding the auxiliaries into the mixed materials, adding water, and kneading the mixture to form a humid material without obvious blocks; (3) transferring the kneaded material to a granulator for granulation; (4) drying obtained soluble granules at the temperature of not more than 50 DEG C for 2 hours, and sieving the soluble granules by a sieve to obtain glyphosate soluble granule finished products.

Description

technical field [0001] The invention belongs to the technical field of pesticide adjuvants, and more specifically relates to a glyphosate ammonium salt soluble granule adjuvant and a preparation method thereof. Background technique [0002] In 1971, Monsanto developed the epoch-making broad-spectrum herbicide glyphosate (Glyphosate) in world agriculture. In the mid-to-late 1970s, it launched glyphosate isopropylamine salt, amine salt and sodium salt; Sulfonium salts. At present, glyphosate has become the most widely used pesticide variety with the largest output in the world, and its annual sales have always ranked first among pesticides. [0003] Glyphosate is a high-efficiency, low-toxicity, broad-spectrum herbicide. It can not only control annual weeds, but also control perennial deep-rooted weeds. It is often used as a herbicide and is mainly used in orchards, mulberry fields, and tea gardens , rubber plantations and sugar cane plantations weeding. In addition, it can...

AI Technical Summary

Problems solved by technology

Ethoxylated fatty amines (such as tallow amine polyoxyethylene ether) are widely used as special additives for glyphosate. Although they have good synergistic performance, they still have relatively serious shortcomings, especially their harmful effects on skin and eyes. It is highly irritating and highly toxic to fish and other aquatic organisms. Therefore, developing its substitutes or reducing its irritating effect on skin and eyes through compounding has become a research hotspot at home and abroad.
