Abstract
The invention relates to the field of pesticide preparations and discloses a pest-killing disease-prevention suspended seed coating. The suspended seed coating comprises the following components in percentage by weight: 5.0-40% of fluopicolide, 1.0-20% of fipronil, 2.0-8.0% of wetting dispersant, 0.5-4.0% of film former, 1.0-4.0% of pesticide warning colouration dye, 0.1-2.0% of tackifier, 1.0-5.0% of antifreezer, 0.1-1.0% of preservative, 0.1-0.8% of foamer and the balance of distilled water. Compared with single fluopicolide or fipronil, the pest-killing and disease-prevention effect is remarkably improved, the seed germination rate can be also increased at the same time, and the seed germination rate of a coated seed can be increased by 5-8% in comparison with that of an uncoated seed. The suspended seed coating is convenient to use and can be mechanically or manually mixed with the seed to meet the demands of different users at the same time.
Description
Technical field
The present invention relates to the pesticidal preparations field, relate to specifically a kind of pesticidal disease-prevention suspending seed coating agent.
Background technology
On producing, because the surface of the seed or carry disease germs in inside, insect in fungus in soil or the soil, muroid causes harm and birds are caused harm, or because the soil nutritional deficiency, the disease seedling usually appears behind the planting seed, scarce nest, the phenomenon of being short of seedling that weak seedling and insect pest etc. cause, the harm that the quarantine harmful organisms that causes great harm, particularly seed to carry to production causes is larger.For this reason, people have summed up many seed processing technologies in production practices, wherein soak seed and the application of the technology of dressing seed is caused harm to control sick worm in seedling stage and played a good role, but because seed soaking and seed dressing effect are single, the drug effect phase is short, medicament comes off easily and causes environmental pollution, and storage tolerance etc. is former thereby allow use and be subject to certain limitation after the seed treatment.Last century the '30s, Europe begins to carry out with binding agents such as flour, dextrin the dressing research of crop seed, but make slow progress, to the sixties, the former Soviet Union appears the concept that proposition " is planted the clothing agent " for the first time, namely bactericide, agrochemical active principle and auxiliary aid is processed special-purpose formulation by being processed to form seed pelleting.Its use has improved seed dressing and the existing disadvantage of soaking seed to a certain extent, has improved seed quality and scientific and technological content, and prevention and elimination of disease and pests forms large-area diffusion and trans-regional propagation with allocation and transportation, the popularization of seed effectively.Along with the development of the Chemical Engineering Technologies such as macromolecular water-soluble compound, the research and development of novel film forming agent has further promoted the promotion and application of seed coating technology.Cenospecies clothing agent and be used for seed soaking, the emulsifiable concentrates for agricultural chemicals of seed dressing, pulvis, the differences such as wetting powder, the agent of kind of clothing is to wrap on the seed immediately that film-forming is kind of a clothing, kind of clothing meets in soil that water imbibition is breathed freely and dissolved hardly, thereby seed is normally germinateed, the materials such as agricultural chemicals and seed manure are slowly discharged, has the soil insect of killing, prevent seed-borne fungi and sprout term disease, promote the seedling healthy growth and development, improve crop quality, improve percentage of seedgermination, reduce seed and agricultural chemicals usage amount, improve the functions such as output, reach environmental contamination reduction, the purpose that preventing disease pest control is kept a full stand of seedings.In addition, the use of planting the clothing agent both guaranteed seed-pelleting, standardization, also stopped the grain kind regardless of, effectively prevent seed manage in the circulation of fake and forged seed.Thereby accelerated the process of seed industry.
The at present kind clothing agent used of Spread in China is various in style, but mostly has some problems, such as the Garrick show, when suitable happy, the red function singleness of enemy committee, only has prophylaxis effect, and operation technique is complicated, and is poor to crop safety; Product such as the toxicity such as thimet, methyl sulphur phosphorus that can effectively prevent and treat soil insect are larger.Therefore it is lower to be badly in need of a kind of toxicity of exploitation, good to underground pest controling effect, and can prevent and treat the product of multiple diseases.
