Abstract

The invention belongs to the technical field of pesticide preparations, and particularly relates to a suspension seed coating containing imidacloprid. The seed coating is prepared from the following raw material ingredients in parts by weight: 45-55 parts of imidacloprid, 12-18 parts of dispersant, 6-8 parts of a wetting agent, 4-7 parts of a film-forming agent, 0.5-1.5 parts of pH regulator, 1-3parts of an anti-freezing agent, 0.2-0.8 part of a defoaming agent, 3.2-4.8 parts of stabilizer and 2-3 parts of a coloring agent, wherein the stabilizer is mixed by sodium alginate, lecithin and maleic hydrazide in a mass ratio of 4:1.7:(1-2). The suspension seed coating containing imidacloprid has high content of imidacloprid, has good storage property by adding specific stabilizer, can be usedfor keeping the stability of preparation in two-year storage period, and can be used in the next year if the seed coating is not used up in the year.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparations, in particular to a suspension seed coating containing imidacloprid. Background technique [0002] Seed coating agent is a kind of pesticide preparation with film-forming properties used for coating crops or other plant seeds, usually composed of pesticide raw materials, dispersants, wetting agents, film-forming agents, pH regulators, antifreeze agents, defoamers It can be directly diluted and coated on the surface of seeds to form a protective film with certain strength and permeability, so it is called seed coating agent. [0003] Imidacloprid is a super-efficient neonicotinoid insecticide with broad-spectrum, high efficiency, low toxicity, and low residue. It is not easy for pests to develop resistance, and it is safe for humans, animals, plants, and natural enemies. It also has contact, stomach, and systemic toxicity. and other multiple effects; after the pests are exposed to t...
