example 1

[0013] 982g of glyphosate ammonium salt with a purity of 97%, 5g of potassium phosphate, and 2g of xanthan gum were ultrafinely pulverized; 22g of alkyl glycosides were added to the pulverized mixture, and the mixture was carried out in a pear-knife type gravity-free mixer. Mix without gravity. During the mixing process, add 40g of tap water by spraying. The mixing time is to observe that the material is loose and does not agglomerate, does not become thinner, and does not generate heat. This process is about 5 to 10 minutes, and then carry out rotary side extrusion granulation or Twin-screw extrusion granulation, and then drying at 70°C through a fluidized bed dryer to obtain a white glyphosate ammonium salt soluble granule of the present invention with a particle size of 0.5 mm; wherein the glyphosate ammonium salt content is 95%, Alkyl glucoside content 1.1%, potassium phosphate content 0.4%, xanthan gum 0.2%, moisture content 0.5%, impurity 2.8% (the impurity is the impurit...

example 2

[0015] 936g of glyphosate ammonium salt with a purity of 97%, 20g of sodium phosphate, 4g of xanthan gum, and 20g of sodium sulfate are subjected to ultrafine pulverization; 41g of alkyl glycosides are added to the pulverized mixture, and they are mixed in a pear knife without gravity Gravity-free mixing is carried out in the container. During the mixing process, 30g of tap water is added by spraying. The mixing time is to observe that the material is loose, not agglomerated, not thinner, and not hot. This process is about 5 to 10 minutes, and then extruded with twin-screws The granulator is granulated, and then dried at 90° C. through a fluidized bed dryer to obtain a white glyphosate ammonium salt soluble granule of the present invention with a particle size of 0.6 mm; wherein the glyphosate ammonium salt content is 90%, and the alkane Glycoside content 2.0%, sodium phosphate content 2%, xanthan gum 0.4%, sodium sulfate 2%, moisture content 1.0%, impurity 2.6%; dry granules a...

example 3

[0017] 896g of glyphosate ammonium salt with a purity of 95%, 20g of sodium trifocus phosphate, 40g of ammonium sulfate, and 4g of xanthan gum were ultrafinely pulverized; Gravity-free mixing is carried out in a gravity-free mixer. During the mixing process, 30g of tap water is added by spraying. The mixing time is to observe that the material is loose and not agglomerated, does not become thinner, and does not generate heat. This process is about 5 to 10 minutes, and then rotate side extrusion granulation, and then dried at 100°C by a fluidized bed dryer to obtain a white glyphosate ammonium salt soluble granule of the present invention with a particle size of 0.7mm; wherein the glyphosate ammonium salt content is 85%, and the alkane Glycoside content 4.1%, sodium tripolyphosphate content 2%, ammonium sulfate 4%, xanthan gum 0.4%, water content 1.5%, impurity 3%; dry granules pass through electric vibrating sieve powder, qualified granules are packed with pesticide granules M...

Abstract

The invention provides a formula of soluble granule (WSG) of glyhosate ammonium and a preparation method. The formula includes 50-95 percent of glyhosate ammonium, 0.5-25 percent of glyphosate synergistic agent, 0.27-40 percent of phosphate, 0-10 percent of filler, 0.1-0.5 percent of xanthan gum and water. The product is stable in property and not prone to absorb moisture, and the production process is simple and smooth, does not pollute the environment and meets environment-protective requirements.

Description

Technical field: [0001] The invention relates to a herbicide, in particular to a glyphosate ammonium salt soluble granule and a production method. Background technique [0002] Glyphosate is a high-efficiency, low-toxicity, and low-residue herbicide successfully developed by Monsanto in the United States in 1974. With the large-scale promotion of glyphosate-resistant transgenic crops, glyphosate has become the most produced and used herbicide at present. varieties. Since glyphosate is insoluble in water and most common organic solvents, it is usually processed into ammonium salt, isopropylamine salt, potassium salt, dimethyl ammonium salt, sodium salt, etc. Due to cost and technical reasons, 10% glyphosate (ammonium salt) aqueous solution, 10% glyphosate (sodium salt) aqueous solution, 41% glyphosate isopropylamine saline solution and 62% glyphosate are mainly used in the market. Isopropylamine saline solution; and soluble granules and soluble powders with a content of abo...
