Embodiment Construction

[0038] A medicinal fertilizer granule containing chlorfenapyr of the present invention is composed of the following raw materials: chlorfenapyr original drug, carrier fertilizer, slow-release agent, binder, coating agent, and filler. Based on the total weight of chlorfenapyr fertilizer granules, including: 0.02% to 2% of chlorfenapyr, 10% to 60% of carrier fertilizer, 0.1% to 2% of slow release agent, 0.1% to 10% of binder, including Film agent 0.1% ~ 0.5%, the rest is filler.

[0039] like figure 1 As shown, mix 0.02%-2% chlorfenapyr technical material, 10%-60% carrier fertilizer, 0.1%-2% slow-release agent, 0.1%-10% binder, 0.1%-0.5% coating agent, After the appropriate amount of filler is mixed evenly in a closed mixing tank, it is added to the granulation equipment for coating granulation, dried at 80 ° C ~ 100 ° C until the water content of the particles is less than 3%, and then sieved. The particle size range is 2000um ~ 4000um, After passing the inspection, the requi...

Abstract

The invention discloses chlorfenapyr drug fertilizer granules and a preparation method thereof. The chlorfenapyr drug fertilizer granules adopt chlorfenapyr as an active component, and comprise the following components by weight: 0.02-2% of chlorfenapyr, 10-60% of carrier fertilizer, 0.1-2% of controlled release formulations, 0.1-10% of binding agent, 0.1-0.5% of membrane enveloping agent and the rest amount of filler. The components are evenly mixed, are pelletized by the membrane enveloping method, are dried and are screened to prepare the chlorfenapyr drug fertilizer granules. The chlorfenapyr drug fertilizer granules provided by the invention can implement the topdressing, and can kill chilo suppressalis and tryporyza incertulas of rice in once application of crop production.

Description

technical field [0001] The invention relates to a chlorfenapyr medicinal fertilizer granule and a preparation method thereof. Background technique [0002] Chlorfenapyr, chemical name: 4-bromo-2-(4-chlorophenyl)-1-(ethoxymethyl)-5-(trifluoromethyl)pyrrole-3-carbonitrile, English name: chlorfenapyr , the product is a new type of pyrrole insecticide and acaricide. It has stomach poisoning and contact killing effects on a variety of pests, is safe for crops, and has the advantages of high control efficiency, long-lasting effect period, and low dosage for preventing and controlling Lepidoptera pests, Homoptera pests, and mites. [0003] In the existing application technology of chlorfenapyr, the formulations of chlorfenapyr include suspension concentrate, microemulsion, and water emulsion. The application method of using this type of formulation is spraying with water to control beet armyworm, diamondback moth, and rice stem borer. , rice stem borer, tea leafhopper, red spider...
