Embodiment 1

[0053] Example 1: Process the solid original drug thiamethoxam, pyraclostrobin, fludioxonil, and difenoconazole to more than 800-1000 mesh by jet crushing method, and then accurately weigh 20% of thiamethoxam , pyraclostrobin 10%, fludioxonil 8%, difenoconazole 10%, dispersant alkylnaphthalene formaldehyde condensate sulfonate 6%, wetting agent alkylnaphthalene sulfonate 4%, viscose Mixture of 5% alkyl aryl polyoxyethyl ether and filler kaolin is fully mixed and evenly mixed. Finally, it can be packaged as 48% thiamethoxam, pyraclostrobin, and fludiox after all technical indicators pass the quality inspection. Nitrile difenoconazole wettable powder.

Embodiment 2

[0054] Example 2: Process the solid original drug thiamethoxam, pyraclostrobin, fludioxonil, and difenoconazole to more than 800-1000 mesh by jet crushing method, and then accurately weigh 20% of thiamethoxam , pyraclostrobin 10%, fludioxonil 8%, difenoconazole 10%, dispersant alkylnaphthalene formaldehyde condensate sulfonate 6%, wetting agent alkylnaphthalene sulfonate 4%, viscose 5% mixture of alkyl aryl polyoxyethyl ether, deionized water is added to 100% for initial mixing, shearing, stirring, and dispersing. After being prepared into slurry, it is ground for 1-2 hours by a horizontal sand mill to make the particles The diameter is less than 5 microns, and it has a certain viscosity and is a flowable 48% liquid suspension preparation of thiamethoxam, pyraclostrobin, fludioxonil, and difenoconazole.

Embodiment 4

[0055] Example 4: Process the solid original drug thiamethoxam, pyraclostrobin, fludioxonil, and difenoconazole to more than 800-1000 mesh by jet crushing method, and then accurately weigh 20% of thiamethoxam , pyraclostrobin 10%, fludioxonil 8%, difenoconazole 10%, dispersant alkylnaphthalene formaldehyde condensate sulfonate 6%, wetting agent alkylnaphthalene sulfonate 4%, viscose The mixture of alkyl aryl polyoxyethyl ether 5% filler kaolin and appropriate amount of water is fully mixed and stirred to form a plastic material, which is extruded and granulated, dried, sieved and finally packaged after passing the quality inspection and various technical indicators. 48% thiamethoxam · pyraclostrobin · fludioxonil · difenoconazole water dispersible granules.

Abstract

The invention relates to a desinsection / sterilization seed treatment compound and an application of the compound, wherein the desinsection / sterilization seed treatment compound is composed of thiamethoxam, pyraclostrobin, fludioxonil and difenoconazole. The compound comprises the following components: 1-30 % of thiamethoxam, 1-30 % of pyraclostrobin, 1-35 % of fludioxonil, 1-35 % of difenoconazole, 1-5 % of dispersant, 1-5 % of wetting agent, 1-5 % of binder, and the balance of filler (or de-ionized water). Through the combination and use of the compound, the unexpected seed effect is achieved, not only the effects of preventing and treating each bacterium harmful to rice are enhanced, but also the use cost is reduced, and the utility ratio of the effective component is improved.
