Abstract
The present invention relates to a pymetrozine water emulsion and a preparation method thereof. The pymetrozine water emulsion includes the components by weight: 1-20%of pymetrozine, 5-20% of a solvent, 5-15% of a cosolvent, 4-15% of an emulsifier, 1-5% of a stabilizer, 0.5-2% of a dispersant, 1-5% of an antifreezing agent, and the balance deionized water. The preparation method includes: dissolving the pymetrozine in the solvent, then adding a certain proportion of the emulsifier, the stabilizer, the dispersant and the antifreezing agent, stirring fully in a preparation kettle to make into an oil phase, slowly adding deionized water to make up to 100% after stirring, shearing for 0.5-2 hours to obtain a milky white pymetrozine water emulsion, and finally dividing and packaging into a finished product. The pymetrozine water emulsion is efficient in preparation form, low in toxicity, environmental-friendly, safe for human and animals, and difficult to produce drug-resistant for diseases.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of pyrrole aphid ketone aqueous emulsion and preparation method thereof.
Background technology
The pyridines insecticide that pyrrole aphid ketone is a kind of efficient, low toxicity, low-residual, the lasting period is long, interior absorption is strong is the brand-new non-insects agent of killing livestock, and the sucking pest of various crop is shown excellent control efficiency.Utilizing electricity to penetrate figure (EPG) technology studies show that, no matter be drop, feed or test injection, almost produce the lancet blocking effect immediately, stop to get food at once as long as aphid or plant hopper one touch pyrrole aphid ketone, and final hungry causing death, and this process is irreversible.
Mainly concentrate on pyrrole aphid ketone or pyrrole aphid ketone and other agricultural chemicals hybrid process wetting powders, water dispersible granules about the patent of pyrrole aphid ketone.And the modern formulations of pesticide are towards water baseization, ultramicronising, no efflorescence and the development of sustained release aspect, promptly be the formulations of pesticide of matrix with water, wherein aqueous emulsion be a kind of organic solvent can be less with in addition the novel pesticide formulation of no, good drug efficacy, environmentally-friendly water-basedization, also be a kind of good liquid dosage form that replaces emulsifiable concentrates for agricultural chemicals, pulvis.1-20% pyrrole aphid ketone aqueous emulsion of the present invention has efficiently, low toxicity, environmentally friendly, person poultry safety, the characteristics of easy degraded, to substitute pulvis to a great extent, not only investment and cost of equipment are low, also can greatly reduce production costs, save a large amount of petrochemical industry resources, and the present invention adopts the solvent of low toxicity, significantly reduce organic solvent to the pollution of human body and environment and residual, produce pollution, explosive and poisoning problem in avoiding producing, pesticide processing is hanged down poison, ensure human and mammiferous safety and health.
Summary of the invention
Purpose of the present invention is exactly to overcome the environmental pollution that exists in the prior art, be detrimental to health and shortcoming such as use cost height and a kind of high-load of developing environment-friendly type, availability height, and pyrrole aphid ketone aqueous emulsion easy to use.
Technical scheme of the present invention: a kind of pyrrole aphid ketone aqueous emulsion, each component is as follows by weight percentage: pyrrole aphid ketone 1-20%, solvent 5-20%, cosolvent 5-15%, emulsifier 4-15%, stabilizing agent 1-5%, dispersant 0.5-2%, antifreezing agent 1-5%, surplus is a deionized water.
