Embodiment 1

[0027] Preparation of 90% fomesafen soluble granules:

[0028] Add 107 grams of tap water, 100 grams of methanol, and 70 grams of 99% caustic soda (sodium hydroxide) to a 2000ml flat-bottomed beaker. Stir fully to dissolve the caustic soda, then slowly add 700 grams of 98.5% fomesafen under stirring. For the original medicine, until the original medicine of fomesafen is completely dissolved, add 8 grams of binder (glucose) and 15 grams of surfactant (alkylphenol polyoxyethylene ether: sodium dodecyl benzene sulfonate = 1:1) ) Continue to stir for 30 minutes to obtain 1000 g of fomesafen liquid, which is then transported to a small spray-drying prilling tower for spray granulation to obtain 760 g of fomesafen soluble granules.

[0029] With reference to the national standard B22169-2008, the mass content of the active ingredient fomesafen is 90.03% and the water content is less than 0.5% by the external standard method of liquid chromatograph.

Embodiment 2

[0031] Preparation of 60% fomesafen soluble granules

[0032] Add 215 grams of tap water, 80 grams of ethanol, 45 grams of 99% caustic soda (sodium hydroxide) into a 2000ml flat-bottomed beaker and stir thoroughly to dissolve the caustic soda, and then slowly add 440 grams of 98% fomesafen under stirring. Until the fomesafen original drug is completely dissolved, add 150 grams of ammonium sulfate filler, 40 grams of binder (glucose), 30 grams of surfactant (fatty alcohol polyoxyethylene ether, sodium dodecyl benzene sulfonate) =2:3) Continue to stir for 30 minutes to obtain 1000 g of fomesafen liquid, and then transport the water to a small spray-drying prilling tower for spray granulation to obtain 685 g of fomesafen soluble granules.

[0033] According to the national standard B22169-2008, the mass content of the active ingredient fomesafen measured by the external standard method of liquid chromatograph is 61.83% and the moisture content is less than 0.5%.

Embodiment 3

[0035] Preparation of 85% Benazone soluble granules

[0036] Add 170 grams of tap water, 100 grams of methanol, and 100 grams of 99% caustic soda (sodium hydroxide) into a 2000ml flat-bottomed beaker. Stir fully to dissolve the caustic soda, and then slowly add 600 grams of 98% mediaxone technical under stirring. , Until all the original medicinal powder is dissolved, add 10 grams of binder (carboxymethyl cellulose), 20 grams of surfactant (alkylphenol polyoxyethylene ether: sodium lauryl sulfonate = 1:1) Stirring is continued for 30 minutes to obtain 1000 grams of triazone water, which is then transported to a small spray-drying granulation tower for spray granulation to obtain 675 grams of triazone soluble granules.

[0037] The mass content of the active ingredient of the active ingredient of the liquid chromatograph is 85.22% and the moisture content is less than 0.5%.

Abstract

The invention provides farm chemical soluble granules and a preparation method thereof. The mass content of effective components in the soluble granules is 60%-90%, and the effective components are one or a mixture of two of fomesafen, bentazone, imazamox, imazapic and acifluorfen-sodium. The soluble granules prepared by the invention have the advantages of high content, convenience in packaging and low transportation cost, and can be automatically dissolved in water, so that the farm chemical effect is greatly exerted; and no dust is generated in the production and use processes, so that thegranules are environment-friendly.

Description

Technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to a high-content pesticide soluble granule and a preparation method thereof. Background technique [0002] Since pesticides must be processed and formed into a certain form of preparation before they can be used in the field to kill insects and weeds. Therefore, the quality of the formulation directly affects the efficacy, use cost and environmental impact of pesticides. The current development direction of pesticide processing formulations is to use water instead of organic solvents to reduce environmental pollution; second, to replace powders with soluble granules to prevent dust hazards and drift to off-target crops during use and cause phytotoxicity . [0003] Among them, the soluble granules can disintegrate quickly after entering water, evenly dissolve in water, can be completely diluted, the solution is uniform and stable, the solution is complete, can really form a...
