Abstract

The invention relates to a seed coating agent which comprises benfuracarb of insecticide as an active componet and high polymers like polythene alcohol or polypropylene acidamide as film-builders. With additives said seed coating agent can be processed into water-emulsion, hung-emulsion and dry powered type; the seed coating agent can be fixed to be insecticide and bactericide combined seed coating agent with additional bactericides as thiram, tebuconazole, N-butyl pertluorooctane sulfonamide, metalaxyl, carbendazol, prochloraze or seedvax as second active component. Said seed coating agent is mainly used to prevent aphid of corn, soja, paddy or cotton and a plurality of underground pest; and the combined type can treat black silk disease, kernel smut, stem rot in seedling stage and anthrax.

Description

technical field [0001] The invention relates to a kind of seed coating agent containing active ingredient carbofuran (Benfuracarb) insecticide, and using a film-forming agent to treat crop seeds, used for corn, soybean, rice, cotton and other crops to prevent and control aphids and polyps Subterranean pests. Background of the invention [0002] Seed coating agent is made of insecticides, fungicides, compound fertilizers, trace elements, plant growth regulators, slow-release agents and film-forming agents through advanced processing, and can be directly or diluted and wrapped on the surface of seeds. Form a pesticide formulation with a certain strength and permeability protective film. The seed coating agent is used before sowing, which can comprehensively prevent and control plant diseases and insect pests at the seedling stage, save medicine, time, labor, and money, and is beneficial to environmental protection. After coating, it can also promote crop...
