Insect-killing and disease-preventing suspension seed coating formulation

Abstract

The invention relates to the field of a pesticide preparation, discloses an insect-killing and disease-preventing suspension seed coating formulation, and relates to a suspension seed coating formulation mixed by fipronil and difenoconazole serving as effective components and a preparation method thereof. The suspension seed coating formulation comprises the following components in percentage by weight: 2.0 to 20 percent of fipronil, 1.0 to 20 percent of difenoconazole, 1.0 to 8.0 percent of wetting dispersant, 1.0 to 10.0 percent of film forming agent, 1.0 to 10.0 percent of coloring agent, 0.1 to 2.0 percent of tackifier, 0.1 to 1.0 percent of preservative, 0.1 to 1.0 percent of antifoaming agent, and the balance of distilled water. The suspension seed coating formulation has the advantages of good film forming property, uniform coating, high suspension rate, safety and low toxicity, good pesticide effect, long persistent effect, high work efficiency, economy and safety, so that the environmental pollution can be reduced, the pesticide utilization is improved, and the pesticide usage is reduced. The suspension seed coating formulation is suitable for seed treatment.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to a suspension seed coating agent for killing insects and preventing diseases. Background technique [0002] In modern agricultural production, seed pesticide treatment is one of the most economical and convenient methods to prevent and control underground pests and crop soil-borne and seed-borne diseases. [0003] Seed coating technology is a widely used new seed treatment technology developed on the basis of traditional seed soaking or seed dressing technology. The seeds in the dry or wet state are coated with a combination of pesticides or fertilizers containing binders to form a protective layer with certain functions and coating strength outside the seeds. This process is called seed coating. The combined substance outside the seed is called seed coating agent, which is a kind of pesticide preparation with film-forming properties used for crop or other plant seed treatme...

AI Technical Summary

Problems solved by technology

[0004] At present, there are many kinds of seed coating agents promoted and used in China, but most of them have some problems, such as Li Kexiu, Shileshi, and Seed Dressing Shuang, etc. have single functions, only have disease prevention effects, and the use technology is complicated, which is not safe for crops; the application number is The Chinese patent of 98106559.7 discloses a seed coating agent, which has both insecticidal and bactericidal effects, but one of its combinations can only be used for wheat and corn seeds, and the other can only be used for cotton seeds , but cannot be used as a seed coating agent for various crop seeds at the same time, and the application range is narrow
