Abstract

A coating agent for corn seeds contains chlorpyrifos, tebuconazole, emulsifier, disperser, filming agent, antifreezing agent and water.

Description

A kind of coating agent for seed

Affiliated technical field:

The present invention relates to formulation processing, be applied to the chemical protection of plant field, specifically a kind of is the corn seed seed coating medicine of Main Ingredients and Appearance with chlopyrifos and Tebuconazole.

Background technology:

Chlopyrifos be a kind of have tag, stomach toxicity and fumigation action, and in soil long insecticide of residence time, good to the control efficiency of underground insect; Tebuconazole is a kind of novel systemic bactericide, can be fabulous prevent the various crop sprout term disease.Two kinds of medicaments use separately, and the property of medicine is single, and can not play can desinsection, effect that again can sterilization.

Summary of the invention:

It is composite that purpose of the present invention is exactly to be with chlopyrifos and Tebuconazole that effective ingredient is carried out, and gives full play to the advantage of the two.The purpose that a dispenser can reach desinsection, cure the disease, the two mutual supplement with each other's advantages not only saves time but also laborsaving.

The present invention is a composite insecticidal sterilization pesticide mixture, consists of two kinds of effective ingredients of A and B.Effective ingredient A is a chlopyrifos, english common name is chlorpyrifos, and chemical name is O, O-diethyl-O-(3,5, the 6-trichloro-2-pyridyl) phosphorothionate, effective ingredient B are Tebuconazole, and english common name is tebuconazole, chemical name is (RS)-1-(4-chlorphenyl)-4,4-dimethyl-3-(1H-1,2,4-triazolyl methyl) amyl alcohol-3.The effective ingredient chlopyrifos accounts for the 1%-30% of mixture gross weight, Tebuconazole accounts for the 0.05%-10% of mixture gross weight, emulsifier accounts for the 1%-15% of mixture gross weight, dispersant accounts for the 1%-10% of mixture gross weight, film forming agent accounts for the 1%-8% of mixture gross weight, antifreezing agent accounts for the 0.1%-10% of mixture gross weight, and water accounts for the 40%-85% of mixture gross weight.After component is determined by best proportioning, respectively chlopyrifos, Tebuconazole, emulsifier, dispersant, film forming agent, the water that measures was dropped into the sand milling still about 10 minutes, discharging is analyzed qualified packing and is got final product.

The present invention's combination measures by best proportioning, fully mixes, and after the sand milling still grinds, promptly obtains processed finished products.The said preparation chemical property is stable, 54 ± 2 ℃ of sealings are stored after heat in 14 days storage resolution ratio less than 5%, and suspensibility reaches country to kind of the requirement of clothing agent more than 90%, the present invention combines the efficient insecticide of chlopyrifos and Tebuconazole, the advantage of broad-spectrum sterilization by composite.From the mechanism of action, there is the potential possibility of insecticidal activity height, sterilization wide spectrum.
