A kind of glyphosate ammonium salt soluble granule 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 additives, and more particularly relates to a glyphosate ammonium salt soluble granule and a preparation method thereof. Background technique

[0002] In 1971, Monsanto Company developed Glyphosate, a broad-spectrum herbicide with epoch-making significance in world agriculture. In the mid and late 1970s, it introduced isopropylamine, amine and sodium salts of glyphosate; ICI launched trimethyl in 1989 Matte salt. At present, glyphosate has become the world's most widely used pesticide variety with the largest output, and its annual sales have always ranked first among pesticides.

[0003] Glyphosate is a highly effective, low-toxic, broad-spectrum herbicide. It can not only control annual weeds, but also control perennial deep-rooted weeds. It is often used as a biocidal herbicide and is mainly used in orchards, mulberry gardens, and tea gardens. , Rubber plantations and sugar cane plantations. In a...
