Abstract
The invention relates to prochloraz emulsifiable granules and a preparation method thereof, and relates to an agricultural bactericide. The prochloraz emulsifiable granules comprise the following raw materials in percentage by weight: 20%-60% of prochloraz, 8%-12% of emulsifying agent, 8%-12% of water-soluble polymer, and the balance of carriers. The preparation method comprises the following steps: mixing liquid prochloraz and the emulsifying agent uniformly firstly; adding prochloraz after mixing into a water solution of the water-soluble polymer, and mixing uniformly, thus viscous emulsion is obtained; then adding the carriers into the viscous emulsion, thus a pre-granulating mixture is obtained; and finally granulating and drying. The granules provided by the invention have quick acting and duration, can maintain a long-term superiority effect, and achieve good effect at low concentration.
Description
Technical field
The present invention relates to a kind of agriculture chemicals fungicide, be specifically related to the preparation method of a kind of Prochloraz bactericide and Prochloraz bactericide.
Background technology
Prochloraz is a kind of efficient, wide spectrum, low toxicity type bactericide; there is the multiple actions such as interior suction conduction, prevention protection treatment; by suppressing the biosynthesis of sterol, work; in plant corpus, there is interior suction conduction; the disease that various crop is caused by sac fungi and imperfect fungus has obvious preventive effect; also can be mixed with most of bactericide, Insecticides (tech) & Herbicides (tech), all there is good control efficiency.How middle disease on field crop, fruit and vegetable, turf and ornamental plants is had to treatment and eradicant action.
Traditional Prochloraz has microemulsion, aqueous emulsion, three kinds of formulations of missible oil, and these three kinds of formulations are not enough to some extent aspect quick-acting, lasting effect, the feature of environmental protection, all exist the not good problem of drug effect need to use the Prochloraz of larger dose just can reach the object of desinsection.Especially the Prochloraz product of missible oil formulation, solvent used is mainly the aromatic hydrocarbon substances such as toluene and dimethylbenzene, and these materials are difficult for degraded, and contaminated environment, has wasted again a large amount of petroleum resources, does not meet requirement and the trend of agricultural sustainable development.
Summary of the invention
The object of the invention is, for described defect above, provides a kind of consumption little, has quick-acting and prochloraz emulsifiable granules lasting effect.
Another object of the present invention is to provide a kind of preparation method of Prochloraz emulsification granula.
The object of the invention is to be achieved by the following technical programs.
A prochloraz emulsifiable granules, is characterized in that, comprises the raw material of following weight portion: Prochloraz 20-60%, and emulsifier 8-12%, water-soluble polymer 8-12%, surplus is carrier.
Described Prochloraz is liquid.
Described emulsifier is selected from a kind of in nonionic and anion compounded surfactant, nonionic phosphate, nonionic sulfuric ester.
Described water-soluble polymer is selected from a kind of in polyvinyl alcohol (PVA), sodium carboxymethylcellulose (CMC), sodium carboxymethyl starch (CMS), by 1:8-12, is made into the aqueous solution.
Described carrier is selected from a kind of in dextrin, sugar, urea, ammonium sulfate, glauber salt, carbonic hydroammonium, Sodium Benzoate, soluble starch.
A kind of preparation method of prochloraz emulsifiable granules; it is characterized in that; first liquid Prochloraz and emulsifier are mixed; mixed Prochloraz is added in the aqueous solution of water-soluble polymer; mix the emulsion that obtains thickness; carrier is added in the emulsion of thickness again and obtain pre-granulation mixture, last granulation is also dry.
The invention has the beneficial effects as follows: tool of the present invention has the following advantages: 1, there is quick-acting and lasting effect, can keep long-term superior effect; 2, use low concentration just can obtain high effect, use the Prochloraz of smaller dose just can reach same bactericidal effect; 3, described emulsifier has high HLB value, be not easy to be saltoutd out, described water-soluble polymer can keep colloidal stability in curing preparation, what can preparation contain the former medicine of a lot of liquid can emulsification granula, described carrier is water-soluble, with the adsorbable a lot of liquid of prilling process of rotary squeezing comminutor extrusion molding; 4, do not add organic solvent, add water emulsification completely during use, drug effect is better than other formulation of identical effective ingredient, and particle body is convenient to packing and transportation.
