Embodiment 1

[0023] First weigh each component: bifenazate 5%, dispersant sodium lignosulfonate 2%, wetting agent alkylphenol polyoxyethylene ether 2%, thickener xanthan gum 0.2%, antifreeze agent B 5% glycol, 0.4% antifoaming agent organic silicone, 0.1% preservative Casson Kaisong, pH regulator to adjust the pH value to 6-8, add water to 100%. After mixing evenly, sand mill to a qualified particle size, and finally add a weighed thickener and shear evenly to form a 5% bifenazate aqueous suspension.

Embodiment 2

[0025] First weigh each component: bifenazate 10%, dispersant polycarboxylate 3%, wetting agent SOPA 1.5%, thickener magnesium aluminum silicate 1%, antifreeze agent ethylene glycol 5%, disinfectant Foaming agent organic silicone 0.4%, preservative Casson Kaisong 0.1%, add water to 100%, pH adjuster to adjust the pH value to 6-8. After mixing evenly, sand mill to a qualified particle size, and finally add a weighed thickener and shear evenly to form a 10% bifenazate aqueous suspension.

Embodiment 3

[0027] First weigh each component: bifenazine 20%, dispersant lauryl polyoxyethylene ether phosphate 4%, wetting agent wetting and penetrating agent T 2%, thickener xanthan gum 0.15%, antifreeze Ethylene glycol 5% as agent, 0.4% organic silicone as antifoaming agent, 0.1% Casson Kaisong as preservative, add water to 100%, and adjust pH value to 6-8 with pH regulator. After mixing evenly, sand mill to a qualified particle size, and finally add a weighed thickener and shear evenly to form a 20% bifenazate aqueous suspension.

Abstract

The invention discloses biphenyl hydrazine ester suspension concentrate, which consists of the following components in percentage by weight: 1%-50% of biphenyl hydrazine ester, 1%-8% of a dispersing agent, 1%-10% of a wetting agent. 0.1%-2% of a thickening stabilizer, 1%-10% of an antifreezing agent, 0.1%-1% of a foaming killer, 0.1%-0.5% of preservative and the balance of water, wherein a pH regulating agent is used for regulating pH value to be 6-8. The invention further discloses a preparation method of the biphenyl hydrazine ester suspension concentrate. The invention provides an environment-friendly biphenyl hydrazine ester water-based suspension concentrate dosage form, which has the advantages of high flash point, safety in production, storage and application, small environmental pollution, low production cost, easiness in packing and the like, and can efficiently and safely meet the requirements of agricultural production.

Description

technical field [0001] The invention belongs to the field of pesticide preparation methods, and in particular relates to a bifenazate aqueous suspension and a preparation method thereof. Background technique [0002] Chemical control is an important means for humans to prevent and control agricultural and forestry diseases and insect pests. Chemical pesticides play a very important role in increasing agricultural production and income. and social issues. Therefore, the development direction of the pesticide preparation industry is to gradually develop towards safety, environmental protection and water-based. Pesticide suspension concentrate refers to a preparation that uniformly disperses solid pesticide original medicine in water with particles below 4 microns. It is an environmentally friendly product that is non-flammable and explosive, has small particle size, high biological activity, large specific gravity, and small packaging volume. Pesticide formulations. [000...
