Example Embodiment

[0020] Example 1:

[0021] 10.5kg of 95% chlorfenuron original drug, 3.0kg of alkylphenol polyoxyethylene polyoxypropylene ether, 5.0kg of phenethylphenol polyoxyethylene sodium sulfate, 1.0kg of potassium sorbate, 4.0kg of ethylene glycol, hydroxymethyl Put 1.0kg of methyl cellulose, 0.2kg of tributyl phosphate and 75.3kg of deionized water into the bucket, turn on the high shear machine to pulverize and mix to make it evenly mixed, and then send it to the sand mill to grind until the fineness of the suspending agent. When the degree reaches the requirement, a 10% chlorfenuron suspension product is obtained.

Example Embodiment

[0022] Example 2:

[0023] 26.4kg of 95% chlorfenuron original drug, 4.0kg of fatty alcohol polyoxyethylene polyoxypropylene ether, 6.0kg of alkylphenol polyoxyethylene ether formaldehyde condensate, 1.0kg of sodium benzoate, 4.0kg of ethylene glycol, xanthan gum 0.5kg, 0.2kg of tributyl phosphate and 57.9kg of deionized water are put into the bucket, turn on the high shear machine to pulverize and mix to make it evenly mixed, and then send it to the sand mill for grinding until the fineness of the suspending agent meets the requirements, that is, 25% chlorfenuron suspension product was obtained.

Example Embodiment

[0024] Example 3:

[0025] 31.6kg of 95% chlorfenuron original drug, 4.0kg of sodium p-methoxy fatty acid amide benzene sulfonate, 7.0kg of phenethylphenol polyoxyethylene sodium sulfate, 1.0kg of potassium sorbate, 4.0kg of polyethylene glycol, yellow Put 0.4kg of original rubber, 0.2kg of silicone defoamer and 51.8kg of deionized water into the bucket, turn on the high shear machine to pulverize and mix to make it evenly mixed, and then send it to the sand mill for grinding until the fineness of the suspending agent reaches Requirement, that is, 30% chlorfenuron suspending agent product is obtained.

Abstract

The invention relates to a pesticide preparation, in particular to a chlorbenzuron suspending agent and a preparation method thereof. The chlorbenzuron suspending agent is prepared by mixing a technical product of chlorbenzuron, a wetting agent, a dispersing agent, an adhesion agent, an antifreezing agent, an antiseptic agent, a defoaming agent and deionized water. The preparation method comprises the following steps of: putting the ingredients in a barrel by a certain proportion, smashing the ingredients by a high shearing machine for evenly mixing, then grinding the above ingredients by a sand mill until the solid grain diameter is less than 4mum, and finally carrying out packing after the quality reaches standard in quality inspection, thus obtaining the preparation. The chlorbenzuron suspending agent has the advantages of having good insect prevention effect, being safe to humans, animals, natural enemies of pests or other beneficial organisms, preventing the large amount of organic solvent from polluting environment, having simple equipment technique and low cost, and being suitable for popularization and application.

Description

technical field [0001] The invention relates to a pesticide preparation, in particular to a diflubenzuron suspension and a preparation method thereof. technical background [0002] In the traditional use of pesticides, mainly emulsifiable concentrates and powders, in the past when the level of productivity was not very high, they played a great role in preventing and controlling pests and diseases. , causing a great burden on the environment during use. Because powder is easy to drift during use, it will bring adverse effects to users and the surrounding environment. It is especially important to develop a new dosage form. [0003] Suspending concentrate is a new dosage form of pesticide processing. It is composed of pesticide original drug, carrier, dispersant and water. It is viscous, flowable, dust-free, low-cost, and high-efficiency. It also has the advantages of wettable powder and emulsifiable concentrate, can be wetted by water, and has good suspension after dilute...
