[0026] 1. Preparation of imidacloprid water-soluble granules

[0027] According to the formula requirements, fully mix imidacloprid, various additives and salts, after being pulverized by a pulverizer, add a certain amount of water, after mixing, use mechanical, airflow or wet sanding, and then spray, squeeze, turntable, Granulation by means of high-intensity mixing, weightlessness, boiling, shaking, etc. can obtain imidacloprid water-soluble granules with different properties.

Embodiment 1

[0028] Embodiment 1 imidacloprid 1% water-soluble granules

[0029] Imidacloprid 10g, potassium sulfate 500g, urea 490g. Stir until fully mixed, pulverize until the particle size is less than 44 μm, add 100 g of water, granulate by extrusion, and dry to obtain imidacloprid 1% water-soluble granules.

Embodiment 2

[0030] Embodiment 2 imidacloprid 2.5% water-soluble granules

[0031] Imidacloprid 25g, ammonium nitrate supplemented to 1000g. Stir until fully mixed, pulverize with a pulverizer until the particle size is less than 44 μm, add 80 g of water, granulate with boiling, and dry to obtain imidacloprid 0.5% water-soluble granules.

Abstract

The invention provides water-soluble granules containing Imidacloprid and containing at least one water-soluble inorganic salt / water-soluble organic substance, wherein, the content of Imidacloprid is 1.0-90.0 percent. The water-soluble granules are used to prevent and kill pests endangering crops, fruit trees, vegetables, pastures, forest, underground and flowers and as well as pests influencing household sanitation in the house; and the granules can be applied to paddy fields, dry fields or households.

Description

technical field [0001] The invention relates to the field of agricultural insecticides, in particular to a water-soluble granule containing imidacloprid, its preparation method and application. Background technique [0002] Imidacloprid is a nitromethylene systemic insecticide, which selectively inhibits the nicotinic acid acetylcholinesterase receptor in the insect nervous system, and highly competitively binds to it to destroy the normal conduction of the insect's central nervous system, making it nervous Paralyzed and died. The product was developed by Bayer for the control of piercing-sucking mouthparts pests such as aphids, leafhoppers, planthoppers, thrips, whitefly and their resistant strains. Also effective against Coleoptera, Diptera, and Lepidoptera. Inactive against nematodes and spider mites. [0003] Currently commercially available imidacloprid preparations mainly include liquids, wettable powders, water-dispersible granules, and suspension concentrates, but...
