Multifunctional superfine powder rice seed coating agent

Abstract

The multifunctional superfine powder rice seed coating agent is compounded with imidacloprid and other pesticide, Seedvax and other germicide, sodium nitrophenolate compound and other plant growth regulator, trace element fertilizer and other active components as well as compound filming agent chitosan and other non-active components, and through superfine grinding and other steps. It can form film automatically while being set in water and may be used for coating rice seed for raising seedling in water, raising seedling in dry land and direct seeding, with the weight ratio between the coating agent and the rice seed being 1 to 300-600. It can prevent diseases and pests of rice seedling for 50-65 days and promote rice seedling growth.

Description

technical field [0001] The invention relates to a preparation for coating treatment of crop seeds, which belongs to the field of novel pesticide preparation technology and crop cultivation technology. Specifically, it is an ultrafine powder multifunctional rice seed coating agent, which is composed of active ingredients such as insecticides, fungicides, plant growth regulators, and trace elements, and inactive ingredients such as composite film-forming agents. Rice seed coating agent prepared by grinding. Background technique [0002] The serious threat of plant diseases and insect pests to the growth of crops, especially the growth of seedlings, has always been a problem that farmers are very concerned about and agricultural experts try to solve. Although traditional seed treatment methods such as medicament soaking and medicament seed dressing have certain effects, the adhesion of the medicament to the seeds is poor, the seeds are easy to fall off and lose when they are t...

Problems solved by technology

[0006] One of the deficiencies of the prior art is that the key film-forming agent used is a single film-forming agent, or the coating film is easily soluble in water, and the coating film is dissolved in water after the coated seeds are soaked or sown to cause its internal activity. The loss of ingredients is serious, the effect is not obvious, and the duration of effect is very short. At the same time, due to the rapid dissolution of the active ingredients, the concentration of the active ingredients around the seeds is too high in a short time, causing phytotoxicity to the seeds; However, the air permeability and water permeability are poor, and the oxygen and water required for seed germination cannot reach the inside of the seed, resulting in difficulty in seed germination, low germination rate and emergence rate

The second main deficiency of the prior art is that the existing rice seed coating agent and upland crop seed coating agent are basically suspension type seed coating agents, which require auxiliary inactive components such as emulsifiers, dispersants, antifreeze agents, and slip agents. The cost of raw materials is high; the production process adopts wet grinding, the process is complicated, and the production cost is high; the content of active ingredients is low, the mass ratio of the coating drug is only 1:30-60, and the storage and transportation costs are high
