Abstract
The invention relates to a preparation method of pesticide preparations, in particular to a preparation method of a procymidone suspending agent. The procymidone suspending agent is formed by mixing procymidone technical with a wetting agent, a dispersing agent, antifreeze, a defoamer, preservative, a thickener and water. The preparation method comprises the following steps of: putting the materials into a bucket according to regulated proportions, and crushing by a high shearing machine so as to uniformly mix the materials; then grinding the materials by a sand mill, and packaging after passing quality inspection to obtain the product of the invention. The procymidone suspending agent takes water as a medium, does not have dust during processing, and is safe to operators and environment.
Description
Technical field
The present invention relates to a kind of preparation method of pesticidal preparations, be specifically related to a kind of preparation method of procymidone suspending agent.Its product is mainly used in diseases such as control ornamental plant gingko seedling stem rot, gingko brown spot.
Technical background
Procymidone english common name procymidone, toxicity belongs to the hypotoxicity bactericide, the disease that Botrytis, cochliobolus genus, Helminthosporium and Sclerotinia are caused has special efficacy, to benomyl, thiophanate-methyl, carbendazim etc. have the pathogen of resistance also effective, can be used alternatingly with medicaments such as carbendazim, can prevent and treat ornamental plant gingko seedling stem rot and gingko brown spot; The gray mold of the eggplant of vegetables, cucumber, tomato, strawberry, first green onion, flowers and grape; Stem rot of the pulse family that is caused by Sclerotinia, lettuce, pepper and peach palm fibre are rotten sick.At present the procymidone formulation products all is to wait based on wetting powder (WP), and the present invention is processed at present in the world advanced person's formulation suspending agent to procymidone.
Suspending agent is a kind of novel form of pesticide processing, form by pesticide original medicine and carrier and dispersant and water, utilize wet method to carry out the flowable preparation of thickness that ultramicro grinding obtains, its product has characteristics such as no dust, cost are low, drug effect height, and have the advantage of wetting powder and missible oil concurrently, can be moistening by water, suspension is good behind the thin up.At present, SC has occupied considerable share in American-European agricultural chemicals market, become one of main formulation, and is the situation of rapid rising.At home, SC also comes into one's own day by day, and existing tens of kinds of pesticidal active substances are developed and are processed into this formulation, the commercialization of realization that has.SC has the gesture that progressively replaces WP, because it has many tangible advantages: product is the water fluid that is suspended with minuteness particle, and the particle average-size is generally 1-2um, has good " four property " (flowability, dispersiveness, plate-out ability, biologically active) characteristics; Be convenient to metering and use; Dustless flying upward when processing and use, all safer to operation, user and environment.
Summary of the invention
The objective of the invention is to propose a kind of preparation method of pesticidal preparations.
Another object of the present invention provides a kind of preparation method of procymidone suspending agent.
A further object of the invention is to provide a kind of novel pesticide product for control ornamental plant disease.
The objective of the invention is to be achieved through the following technical solutions:
Described procymidone bactericidal suspending agent, the percentage by weight that it is characterized in that this each component of suspending agent consists of: procymidone 10-60%, wetting agent 1-5%, dispersant 1-8%, thickener 0.2-5%, antifreezing agent 2-8%, defoamer 0.1-1%, preservative 0.2-1%, surplus is a water.
Described procymidone suspending agent, it is characterized in that used wetting agent be selected from alkylphenol-polyethenoxy polyethenoxy ether, aliphatic alcohol polyethenoxy polyethenoxy ether, calcium lignosulfonate, to any one or multiple combination in methoxyl group fatty acid amide benzene sulfonic acid sodium salt, sorbitol polyoxyethylene base ether, the alkylphenol-polyethenoxy base ether formaldehyde condensation products.
Described procymidone suspending agent is characterized in that used dispersant is selected from one or more combinations in calcium lignosulfonate, sodium lignin sulfonate, alkylphenol polyoxyethylene formaldehyde condensation products, the phenethyl phenol polyethenoxy ether formaldehyde condensation products.
