Abstract

The invention relates to a superfine powder type rape seed coating agent. The superfine powder type rape seed coating agent is prepared by ultrasonically crushing active ingredients including bactericide hymexazol, insecticide imidacloprid, plant growth regulator compound sodium nitrophenolate, trace element fertilizer boric acid and the like, and inactive ingredients including film-forming agent carboxymethyl chitin, pigment, auxiliaries and the like. The superfine powder type rape seed coating agent is suitable for coating treatment of various rape seeds under different ecological conditions; the mass ratio of coated drug to seeds is as high as 1 to 150-180; a coated film with a film pore path is formed on the surface of the seed during a coating process; the active ingredients can be slowly released by the film pore path, so that the prevention and treatment agent for stalk break at the rape seedling period is 83%-97%, and the prevention and treatment rate for aphids and soil insects is 85%-96%; a rape root system is developed and strong in stress resistance, so that the emergence rate is improved by 10%-19%, the seedling emergency percentage is improved by 8%-17% and a yield-increasing effect is obvious. Besides, the superfine powder type rape seed coating agent is simple and convenient to produce, low in cost and convenient to use.

Description

technical field

[0001] The invention relates to a preparation for crop seed coating treatment, and belongs to the fields of novel pesticide preparation technology and rapeseed cultivation technology. Specifically, it is a superfine powder rape seed coating agent, which is composed of active ingredients such as fungicides, insecticides, plant growth regulators, and trace elements, and inactive ingredients such as film-forming agents, colorants, and auxiliary agents. Coating agent for rapeseed prepared by ultrasonic pulverization. Background technique

[0002] Crop 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 seedlings. Diseases and insect pests, promotion and control of seedling growth, saving planting and medicine, saving labor and time...
