Embodiment 1

[0026] Example 1 0.06% dinotefuran soluble granules

[0027]

[0028] Put the water-soluble starch into the intermediate silo, pulverize it through an ultra-fine pulverizer, add the pulverized material to the binder sodium carboxymethyl cellulose for granulation, and obtain the base nucleus; dinotefuran, dispersant and Di-sec-octyl sodium butenedioate and alkyl phosphate as a wetting agent are evenly mixed, and then sprayed on the surface of the base core to obtain a soluble granule containing the active component dinotefuran.

Embodiment 2

[0029] Example 2 1% dinotefuran soluble granules

[0030]

[0031] Add ammonium sulfate, water-soluble starch and alkylphenol formaldehyde resin polyoxyethylene ether sulfate into the mixer after metering, start stirring, and after mixing evenly, put it into the intermediate silo and grind it through an ultrafine grinder. Good materials are added with polyvinyl alcohol as a binder for granulation, and then dried to obtain soluble granules containing dinotefuran as an active component.

Embodiment 3

[0032] Example 3 2% dinotefuran soluble granules

[0033]

[0034] Put the water-soluble starch and ammonium sulfate as the carrier into the intermediate silo, pulverize through the ultra-fine pulverizer, add the pulverized material to the binder polyvinyl alcohol for granulation, and obtain the base nucleus; polystyrene phenol After the oxyethylene ether, EP / PO block copolymer and dinotefuran are mixed evenly, they are sprayed and coated on the surface of the base core to obtain soluble granules containing the active component dinotefuran.

Abstract

The invention provides a soluble granule containing active ingredient dinotefuran and a preparation method of the soluble granule. The soluble granule containing the active ingredient dinotefuran includes the dinotefuran, a dispersant, a wetting agent, a binder and a carrier. The preparation method comprises the following steps: putting the carrier in an intermediate bin, performing crushing by using an ultra-fine crushing machine, adding the binder into the crushed material, and performing granulation to obtain a basic core; and uniformly mixing the dinotefuran, the dispersant and the wettingagent, and spraying the mixture onto the surface of the basic core to obtain the soluble granule containing the active ingredient dinotefuran. The soluble granule has the following advantages: the soluble granule has safety, environmental protection and convenient use, and is used to prevent and control rice pests chilo suppressalis and thrips; and the soluble granule not only overcomes the problem of environmental pollution caused by use of organic solvents in emulsifiable concentrate and microemulsions, but also overcomes the problem of environmental pollution caused by large dust in the production and use of wettable powder.

Description

technical field [0001] The invention belongs to the field of pesticide processing, and relates to the application of dinotefuran soluble granule and its preparation method. Background technique [0002] Rice is one of the most important food crops in China. The sown area of ​​rice in my country accounts for 1 / 4 of the country's food crops, while the output accounts for more than half. Insect pests seriously threaten the yield of rice, and the loss of rice yield due to insect pests is about 10% every year. Among them, the most serious pests are Chilo borer and Thrips. [0003] Dinotefuran, common name in English: dinotefuran, chemical name: 1-methyl-2-nitro-3-(tetrahydro-3-furylmethyl)guanidine. For nicotine insecticides. It has the characteristics of contact killing, stomach toxicity, high quick-acting effect, long-lasting effect period of 3-4 weeks, broad insecticidal spectrum, strong root systemic absorption, etc., and also has the characteristics of being rapidly absor...
