Suspension type rape seed coating agent

Abstract

The invention relates to a suspension type rape seed coating agent formulation. The suspension type rape seed coating agent is prepared by carrying out wet grinding on a film-forming agent, an emulsifier, an anti-freezing agent, a warning color material and insecticide, disinfectant, a plant growth regulator, a trace-element fertilizer and water; and the suspension type rape seed coating agent issuitable for carrying out coating treatment on all sorts of seeds. The rape seed coating agent provided by the invention has the advantages of simple manufacturing technique, convenience for coating and low cost and can be used for mechanical coating or manual coating, and the mass ratio of the rape seed coating agent to the seeds can reach up to 1 to 200-300; when the seeds are coated, a film with dense film pore channels is formed on the surface of each seed; and then the active components can be slowly released through the film pore channels and the lasting period is 55-day-long to 70-day-long; the prevention and cure rate of the coating agent on the rape seedling stage sclerotiniose is up to 86-97% and the prevention and cure rate on the aphid and the subterranean pest-insect is up to82-95%; a rape seedling has the developed roots, is neat and stocky and has strong stress resistance; the rate of emergence of the seedlings is improved by 8-18% and the planting percent is improved by 7-15% so that the yield is obviously increased. The suspension type rape seed coating agent has good economic benefits, social benefits and ecological benefits.

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 a suspension-type rapeseed coating agent, which is composed of active ingredients such as insecticides, fungicides, plant growth regulators, and trace element fertilizers, and inactive ingredients such as film-forming agents and emulsifiers. Rapeseed coating agent prepared by grinding. Background technique [0002] Seed coating is an agricultural high-tech, which can coat pesticides, growth regulators, micro-fertilizers and other active ingredients in the coating film formed on the surface of seeds, and release them slowly during seed germination and growth, effectively preventing and controlling seedling pests and diseases , Promote and control the growth of seedlings, save planting and medicine, save labor and time, save resources, and reduce environmenta...

AI Technical Summary

Problems solved by technology

However, the rape seed coating agent has not been popularized in a large area, and the coating rate of rapeseed is still less than 10%.

The main reason is that the rapeseed coating agent currently developed and tested is basically a pill-type rapeseed coating agent. After the seeds are coated, the pill coat is easy to fall off. Slow germination, low emergence rate and seedling rate

[0005] The prior art has the following three major deficiencies: (1) The pill-type rape seed coating agent forms a very thick pill coating on the seed surface, which has poor compressive strength, and the coated seeds contain pesticides during transportation, storage and sowing The pill coats of active ingredients such as plant growth regulators and plant growth regulators are easy to fall off, not only the loss of active ingredients is large, the effect of seed coating agents is poor, and the environment is polluted

(2) After the pilled seeds are sown, the cracking speed of the pill coat is very slow, and the water and oxygen required for the normal germination of rape seeds in the pill coat are difficult to meet, resulting in low germination potential and significantly delayed emergence

(3) When the pill coat is cracked, the active ingredient dissolves rapidly and the concentration of the active ingredient around the seeds is too high in a short time, which inhibits the germination of rapeseed seeds, resulting in low emergence and seedling rates
