Embodiment 1
[0016] Example 1: 50% Acephate Soluble Granules
[0017] Raw material dosage (weight percent)
[0018] Acephate 50.0
[0019] Polyphosphate 5.0
[0020] Soluble starch 8.0
[0021] Penetrant T 5.0
[0022] Kaolin 32.0
[0023] First, crush polycondensed phosphate and kaolin, and then fully mix with the above-mentioned other ingredients to obtain acephate soluble powder, then add the powder to the inclined rotating disk, spray water for granulation, and dry it to become 50 % Acephate Soluble Granules.
Embodiment 2
[0024] Example 2: 75% Acephate Soluble Granules
[0025] Raw material dosage (weight percent)
[0026] Acephate 75.0
[0027] Urea 3.5
[0028] Polyethylene glycol 1.5
[0029] Azone 3.0
[0030] Bentonite 17.0
[0031] The extrusion granulation method is adopted, that is, the urea and bentonite are pre-crushed, and then fully mixed with acephate and azone, transferred to a kneader, sprayed into an aqueous solution of polyethylene glycol, and fully kneaded. The obtained material is granulated and dried to obtain 75% acephate soluble granules.
Embodiment 3
[0032] Example 3: 90% Acephate Soluble Granules
[0033] Raw material dosage (weight percent)
[0034] Acephate 90.0
[0035] Phosphate ester surfactant 3.5
[0036] Polycarboxylate 1.5
[0037] Tea Saponin 5.0
[0038] The extrusion granulation method is used to fully mix all the components, and transfer to an extrusion granulation granulator for granulation, which is 90% acephate soluble granules.

Abstract
The invention relates to a preparation method of acephate pesticide formulation, specifically a stable acephate soluble granule and preparation method thereof, comprising the following components: 5-97 weight% of acephate, 1-10 weight% of stabilizer, 1-15 weight% of binder, 1-20 weight% of synergist. The acephate granule can enwrap the effective component acephate in the middle of the granule, which can prevent effective component from decomposing with good solubleness and no flying-dust. Thus the preparation method has features of strong stabilization, good drug efficacy, small environmental pollution, simple preparation method and is very suitable for processing pesticide formulation of high content.
Description
technical field [0001] The invention relates to a preparation method of an acephate pesticide preparation, in particular to a stable acephate soluble granule and a preparation method thereof. Background technique [0002] In order to increase the production and income of crops, it is necessary to use a large amount of pesticides every year to recover the loss of crops. Extensive use of pesticides has resulted in environmental pollution. In order to reduce the damage of pesticides to the environment as much as possible, pesticide formulations should be developed in the direction of environmental friendliness and resource conservation. [0003] Acephate is a broad-spectrum, high-efficiency, low-toxicity, and low-residue organophosphorus insecticide. It has stomach toxicity, contact and systemic effects, and has certain fumigation effects. It is suitable for vegetables, rice, cotton, wheat, fruit trees, rapeseed, tobacco and other crops to control more than 100 kinds of pests...
