A kind of multifunctional suspending type special seed coating agent for millet in spring valley area

Abstract

A kind of multifunctional suspending type special seed coating agent for spring valley area, belongs to the technical field of agriculture, comprises insecticide 10-30%, bactericide 6-25%, plant growth regulator 0.05-0.1%, by weight percentage, Film forming agent 2‑6%, dispersant 2‑8%, antifreeze agent 3‑8%, coloring agent 0.5‑1.0%, defoamer 0.2‑0.3%, water balance. The seed coating agent of the present invention is specially suitable for the coating of grain seeds in the spring valley area, and is a suspension-type seed coating agent with the characteristics of high efficiency and low toxicity, firm coating, obvious control effect, long-lasting effect, large drug-to-seed mass ratio, and environmental friendliness. Not only can it effectively prevent and control pests and diseases at the seedling stage, but it can also promote and control growth, enhance stress resistance, and significantly increase the seedling rate.

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...

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
