Embodiment Construction

[0025] Based on the total weight of dinotefuran granules, including: dinotefuran 2%, attapulgite 2%, polyvinylpyrrolidone 0.15%, reactive blue 0.1%, and the balance of quartz sand.

[0026] According to the preparation method of granules of the present invention, the above-mentioned materials are uniformly mixed in a closed preparation kettle, granulated by coating method, dried at 120°C until the water content of the granules is 1%, sieved, and the particle size range is 4000 microns (μm), After passing the inspection, 2% dinotefuran granules are obtained.

[0027] The production process of the granule preparation method of the present invention is mature, and the insecticidal granule with qualified quality and stable effect can be produced according to product standards. In order to verify the stability of product quality, we conducted a thermal storage stability test of the product: store it at 54°C±2°C for 14 days, and measure the decomposition rate, moisture, pH value, et...

Abstract

The invention relates to dinotefuran granules and a preparation method thereof. The dinotefuran granules have effective components of dinotefuran and the balance of pesticide adjuvant and carriers, wherein the mass percent of the dinotefuran in the dinotefuran granules is 0.01-10%. The invention also discloses the preparation method of the dinotefuran granules. The dinotefuran granules provided by the invention are suitable for controlling pests of crops such as rice, wheat, vegetables, fruit trees, etc.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a granule containing dinotefuran. Background technique [0002] Dinotefuran, English common name: dinotefuran, chemical name: 1-methyl-2-nitro-3-(tetrahydro-3-furylmethyl)guanidine, structural formula: [0003] [0004] Dinotefuran is a neonicotinoid insecticide. It is a systemic insecticide that acts through spinal nerve transmission and contact gastric toxicity, can be quickly absorbed by plants and spread widely, and has an excitatory effect on nicotinic acetylcholine receptors. Dinotefuran has excellent control effect on piercing-sucking mouthparts pests, and shows high insecticidal activity at a very low dose. Pteroptera pests are highly effective. Contents of the invention [0005] Technical problem to be solved: the present invention provides a dinotefuran granule for the prior art, which is used to prevent and control pests such as rice, wheat, vegetables, and ...
