Abstract
The invention relates to a dimethomorph-mancozeb water dispersible granule and a preparation method thereof. The dimethomorph-mancozeb water dispersible granule is characterized by comprising the following components by weight percent: 40-65 of dimethomorph, 8-15 of mancozeb, 1-30 of disintegrant, 1-10 of dispersant, 1-10 of wetting agent, 0.1-2 of caking agent, 0.05-0.3 of stabilizing agent and the balance carrier. The preparation method is as follows: the components are weighed by the mixture ratio and are mixed evenly; active ingredient, accessory ingredient and carrier are added to the mixture; master powder is obtained after grinding the formula components in a superfine mode, and the master powder is extruded, prilled, dried and sievedto obtain dimethomorph-mancozeb dispersible granule. The invention overcomes the deficiencies of missible oil harming the environment and powder, has better wetting property, faster disintegration speed, better dispersivity, higher suspensibility, good geothermal reservoir stability and easy use, and is safe to human beings and environment and easy to control the release and the direction finding.
Description
Technical field
The present invention relates to a kind of be used to prevent and treat fungal disease efficient germicide, relate to a kind of dimethomorph-mancozeb water dispersible granule and preparation method thereof specifically.
Background technology
In traditional agricultural chemicals uses, mainly be missible oil and pulvis, the level of the productive forces is not under the very high situation in the past, for prevention and elimination of disease and pests plays a significantly greater role, but, in the process of using, environment has been caused very big burden in organic solvent because missible oil all is that former medicine and emulsifiers dissolve form.Pulvis because in use is easy to drift, brings adverse influence for user and surrounding environment.Water dispersible granules is a kind of pesticides new formulation that grows up the America and Europe early 1980s, also claims to do to suspend, and international pesticide industry federation of association (GIFAR) is defined as it: the granule that use disintegration and dispersion back in water.Water dispersible granules mainly is made up of pesticide active ingredient, dispersant, wetting agent, binding agent, disintegrant and filler, particle diameter 200 μ m-5mm, and disintegration rapidly after the entry disperses, and forms the higher suspension dispersion.Water dispersible granules can be produced highly enriched, the insecticidal formulation that need not to dissolve; Water dispersible granules seldom even substantially can not generate dust (during use), thereby has reduced the toxicity in the operating process; Water dispersible granules can not flow, and makes that metering is more convenient.Be easy to packing, it is more easy to deal with like this.
Dimethomorph is a kind of cinnamic acid derivative, and it has strong active to the fungi of Peronosporaceae and Phytophthora.Mainly be the decomposition that causes the spore cyst wall, thereby make thalline death.Except that zoospore form and the spore swarm stage, all there is effect in each stage of oomycetes history of life, especially more responsive in the formation stage of sporangiophore and egg spore, (＜0.25 mg/litre) promptly is suppressed under extremely low concentration.If medication before sporulation promptly can suppress spore fully and produce.The interior absorption of this medicine is stronger, and the root dispenser can enter each position of plant by root.Foliage spray, medicine also can enter blade interior.It and benzamides bactericide be no cross resistance such as metalaxyl, oxazolidone for example.Mancozeb has the better protect effect, sulfydryl (SH) combination in the inhibition thalline in the dithio-octanoic acid dechlorination enzyme of the oxidation of pyruvic acid and participation pyruvic acid hydrogenation process.There is not cross resistance with other bactericide; Prevention is arranged, treatment and very strong anti-spore effect, general protection crop.The perfect adaptation body of absorption sterilization component and multidigit point protection sterilization component in the cinnamic acid has prevention, treatment double action.Interior absorption is strong, and anti-rainwater is washed away, and the lasting period is long, to downy mildew, eqpidemic disease special efficacy.Lasting period is long, and osmosis is strong, resistance of rainwater washing against.
The dimethomorph-mancozeb dispersible granule does not add organic solvent, the heat storage is stable, is a kind of formulation of environmental protection.The present invention proposes according to these problems.
Summary of the invention
The objective of the invention is to be to disclose a kind of dimethomorph-mancozeb water dispersible granule and preparation method thereof.
Another object of the present invention is to overcome the shortcoming of prior art, provide a kind of with dimethomorph-mancozeb be that the preparation of former medicine is efficient, low toxicity, environment amenable nuisanceless bactericide, can be used for preventing and treating downy mildew and eqpidemic disease.
Purpose of the present invention is achieved through the following technical solutions:
A kind of dimethomorph-mancozeb water dispersible granule, the percentage by weight of each component is in the prescription: dimethomorph 40-65%; Mancozeb 8-15%; Dispersant 1-10%; Wetting agent 1-10%; Disintegrant 1-30%; Binding agent 0.1～2%; Stabilizing agent 0.05～0.3%; Carrier: 0.5-30%.
Described dispersant is selected from: one or more in calcium lignosulfonate, sodium lignin sulfonate, Fluhyzon formaldehyde condensation products (NNO), phenethyl phenol polyethenoxy sodium sulphate, alkylbenzenesulfonate (BX), the alkylphenol polyoxyethylene formaldehyde condensation products.
Described dimethomorph-mancozeb water dispersible granule is characterized in that described wetting agent is selected from one or more in alkylnaphthalene sulfonate condensation product sodium salt, benzyl naphthalene sulfonate, benzyl naphthalenesulfonate formaldehyde condensation compound, sodium alkyl sulfate (K12), dialkyl group naphthalene sulfonate, the fatty acid amide N methyl taurine salt.
Described dimethomorph-mancozeb water dispersible granule is characterized in that described disintegrant is selected from one or more in bentonite, PEG, modified starch, white carbon black, ammonium sulfate, the silica gel.
Described dimethomorph-mancozeb water dispersible granule is characterized in that described adhesive is selected from one or more in Sodium Polyacrylate, PEG, sex change PVA, wooden sodium, dextrin, CMC (and cellulose derivatives), the xanthans.
Described dimethomorph-mancozeb water dispersible granule is characterized in that described stabilizing agent is selected from one or more in sodium methoxide, citric acid, niter cake, carbonic hydroammonium, the sodium hydroxide.
Described dimethomorph-mancozeb water dispersible granule is characterized in that described carrier is selected from one or more in kaolin, diatomite, clay, mica powder, bentonite, attapulgite, sepiolite, calcium carbonate, Emathlite, white carbon, the talcum powder.
The manufacturing process of described dimethomorph-mancozeb water dispersible granule is:
1, one group of dimethomorph-mancozeb water dispersible granule formulation material is mixed;
2, formulation material is ground into female powder through micro jet;
3, after the assay was approved female powder is mixed rotating disk squash type granulation then at a certain proportion of deionized water of adding;
4, defective granulation, the qualified drier drying that enters of profile then returned again of granulation profile;
5, drying, screening be after sample analysis, qualified can the packing;
6, packaging this water-dispersible granules puts in storage.
The water-dispersible granules prior art of prescription of the present invention processing is compared, and it is higher to have a suspensibility, and the heat storage is more stable, disintegration rate is faster, dispersiveness is better; Agent formulation of the present invention is difficult for producing poisoning to environment, people and animals and other beneficial organism safety; The preparation preparing process is simpler, easy to use, cost hangs down and is suitable for large scale application.
