Special multifunctional suspension type seed coating agent for spring-rice-region paddy

Abstract

The invention relates to a special multifunctional suspension type seed coating agent for spring-rice-region paddy and belongs to the technical field of agriculture. The seed coating agent is preparedfrom the ingredients in percentage by weight: 10% to 30% of insecticide, 6% to 25% of bactericide, 0.05% to 0.1% of plant growth regulator, 2% to 6% of film forming agent, 2% to 8% of dispersant, 3%to 8% of antifreezer, 0.5% to 1.0% of colorant, 0.2% to 0.3% of antifoamer and the balance of water. The seed coating agent disclosed by the invention is specially suitable for coating spring-rice-region paddy seeds; the suspension type seed coating agent, having the characteristics of high performance, low toxicity, firm coating, obvious control efficiency, long effect duration, high pesticide/seed mass ratio, environment-friendliness and the like, not only can be used for effectively preventing and controlling seedling-stage plant diseases and insect pests, but also can be used for promotingand controlling growth and enhancing stress resistance, and the percentage of establishment is increased obviously.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to a seed coating agent for grains, in particular to a multifunctional suspension type special seed coating agent for millet in the spring valley area. Background technique [0002] Seed coating is an agricultural high-tech, which can coat pesticides, growth regulators and other active ingredients in the coating film formed on the surface of seeds, and release them during seed germination and growth, effectively preventing and controlling seedling pests and diseases, and promoting the control of seedlings Growth, saving seeds and medicines, saving labor and time, saving resources, and reducing environmental pollution are important ways to standardize seed quality, mechanize processing, refine seeding, lighten cultivation, and increase income and reduce expenditure. Since the date of birth, seed coating agents have been highly valued by many countries, and nearly 30 countries have i...

AI Technical Summary

Problems solved by technology

[0005] The existing millet seed coating agent used in the spring valley area has the following four main shortcomings: (1) because it is a special seed coating agent for non-millet, the agent is not targeted, the seed dressing effect is poor, and it is difficult to control the damage of diseases and insect pests

(2) The existing seed coating agent does not use a special film-forming agent for the problem that the millet seed is small and easy to fall off. The adhesion is poor and it is easy to fall off. The coated seeds contain pesticides and plant growth regulators during transportation, storage and sowing. The seed coats of active ingredients such as chlorophyll are easy to fall off, not only the loss of active ingredients is large, the effect of the seed coating agent is poor, and the environment is polluted

(3) After sowing, the cracking speed of the seed coat is very slow, and the water and oxygen required for the normal germination of the seeds in the seed coat are difficult to meet, resulting in low germination potential and significantly delayed emergence

(4) When the seed coat is cracked, the active ingredient dissolves rapidly and the concentration of the active ingredient around the seed is too high in a short time, which inhibits the germination of the seed, resulting in a low rate of emergence and seedling formation

(5) With continuous use for many years, bacteria are prone to drug resistance, and the control effect is declining year by year
