Ultrafine powder type corn seed coating agent

Abstract

The present invention relates to an ultrafine power type corn seed coating agent, wherein active components such as bactericidal agents including tebuconazole and carbendazim, an insecticide fipronil, a growth regulating agent sodium naphthalene acetate, trace element fertilizer zinc sulfate, borax and the like, and non-active components such as a film forming agent hydroxyethyl chitin, a colorant, an auxiliary agent and the like are subjected to ultramicro airlow grinding so as to prepare the ultrafine power type corn seed coating agent. According to the present invention, the ultrafine power type corn seed coating agent is suitable for coating treatments of various spring corn seeds and summer corn seeds under different ecological conditions, the mass ratio of the coating agent to the seed is 1:185-195, the coating film having the film pore channels can be formed on the seed surface during the coating, and the active components can be slowly released through the film pore channels; in the effect lasting period of 65-80 days, the prevention and control rate on corn root rot, top rot, seedling blight and head smut is 85-93%; the prevention and control rate on euxoasegetum schiffer-muller, elateridae, aphids, and laodelphax striatellus is 82-95%; the corn root system is prosperous, the resistance is strong, the seedling rate is increased by 9-17%, and the yield is increased by 7-13%; and the ultrafine power type corn seed coating agent has good economic, social and ecological benefits.

Description

technical field [0001] The invention relates to a preparation for corn seed coating treatment, which belongs to the field of novel pesticide preparation technology and corn cultivation technology. Specifically, it is a superfine powder corn seed coating agent, which is composed of active ingredients such as fungicides, insecticides, growth regulators, and trace element fertilizers, and inactive ingredients such as film-forming agents, colorants, and auxiliary agents. Corn seed coating agent prepared by ultra-fine airflow pulverization. Background technique [0002] One of the main problems in crop cultivation is the harm of plant diseases and insect pests to the growth of crops. Accompanied by the whole growth cycle of crops, it has always been an important issue that farmers are very concerned about and agricultural experts try to solve. The traditional control methods mainly include chemical seed dressing, chemical seed soaking and other seed treatment methods. Although t...

AI Technical Summary

Problems solved by technology

[0006] In the process of corn production, corn seed coating agents have been developed. However, the existing corn seed coating agent technology has the following main shortcomings: (1) The formulation of existing corn seed coating agents is basically a suspension type. The performance of the coating agent is unstable, it is easy to layer and precipitate, and the active ingredient is easy to decompose

(2) Most of the film-forming agents used are artificially synthesized polymer materials, such as polyvinyl acetate, polyvinylpyrrolidone, etc., which are difficult to degrade in the soil, and the residual soil will pollute the soil; the coating film formed during coating is breathable , Poor water permeability, low germination rate and emergence rate of coated seeds, and short duration of active ingredients

(3) Existing suspension-type corn seed coating agents need to add a large amount of auxiliary ingredients such as emulsifiers, dispersants, defoamers, thickeners, and antifreeze agents. Harmful to the quality of the soil environment
