Abstract
The invention discloses a fungicide-epoxiconazole water dispersible granule. The invention belongs to a fungicides technology in the field of plant protection. The combination of the invention comprises that: 10-800 portion of epoxiconazole, 10-50 portion of wetting agent, 10-50 portion of dispersant, 10-80 portion of disintegrant, 20-100 portion of adhesive agent, 20-100 portion of stabilizer and 50-500 portion of filler; after the ingredients are mixed by proportion and evenly stirred, mesh powder is obtained by pulverization; the epoxiconazole water dispersible granule is made by evenly mixing the mesh powder and the adhesive agent, then through granulating, parching and screening. The invention overcomes weak points of wettable powder, pulvis, ungluing agent, suspension concentrate and emulsifiable concentrate of the epoxiconazole and reduces cost for farmers and pollution of environment. Besides, the invention has the advantages of high content, fast disintegration, upstanding dispersity, easy storing and good stability as well as high reactivity, good effectiveness and favorable safety when in use.
Description
Technical field
The present invention relates to a kind of disinfectant use in agriculture, particularly a kind of epoxiconazole water dispersant with prevention and treatment double action at the development of sigatoka, wheat rust the invention still further relates to the preparation method of this disinfectant use in agriculture.
Background technology
At present, disinfectant use in agriculture is a lot, fluorine ring azoles is wherein a kind of, absorption tricyclic antidepressants bactericide in belonging to, have prevention and treatment double action, it is mainly used in the sigatoka of difficult control, the prevention of wheat rust and treatment, it has active high, efficacy stability, the drug effect continuous and effective phase is long, safety is good, characteristics such as remarkably productive, it is one of product of consumption maximum in the present bacterial disease control, but the fluorine ring azoles wetting powder of Chu Xianing in the market, epoxiconazole suspension concentrate, fluorine ring azoles pulvis, fluorine ring azoles missible oil, it is low that ubiquities such as fluorine ring azoles glue fluorine ring azoles content, disintegration is slow, bad dispersibility, problems such as environmental pollution is serious, and storing is inconvenient, is difficult for packing, the use cost height.
Summary of the invention
The technical problem to be solved in the present invention is for overcoming prior art, cost height, polluting greatly, the shortcoming that storing is inconvenient, provide a kind of use, low, the easy packing of cost, storing conveniently, the healthy nothing injury of people, environmentally safe have been improved the epoxiconazole water dispersant of effective ingredient availability and medication efficient simultaneously again; In addition, the present invention also provides the preparation method of this epoxiconazole water dispersant.
In order to solve the problems of the technologies described above, the present invention realizes as follows: it comprises bulk drug, wetting agent, dispersant, disintegrant, adsorbent and stabilizing agent, carrier and adhesive component; The ratio that various components account for gross weight by weight is:
Bulk drug is that fluorine ring azoles accounts for 10 parts～800 parts
Carrier is that filler accounts for 50 parts～500 parts
Adhesive accounts for 20 parts～100 parts
Wetting agent accounts for 10 parts～50 parts
Dispersant accounts for 10 parts～50 parts
Disintegrant accounts for 10 parts～80 parts
Adsorbent accounts for 10 parts～80 parts
20 parts～100 parts of stabilizer comprises

Described adsorbent newspaper is drawn together a kind of in diatomite, attapulgite, white carbon, No. 45, lignin, the bentonite.
Described adhesive comprises a kind of among gelatin, polyvinyl alcohol, polyvinylpyrrolidone, polyethylene glycol, starch, the CMC.
Described stabilizing agent newspaper is drawn together a kind of in sodium hydrogen phosphate, succinic acid, adipic acid, oxalic acid, the borax.
Described filler comprises a kind of in kaolin, precipitated calcium carbonate, bentonite, the anhydrous sodium sulfate.
The preparation method of epoxiconazole water dispersant of the present invention is undertaken by following step:
1) according to the purposes that will prepare the water dispersant granule pesticide, take by weighing above-mentioned former medicine, auxiliary agent, carrier, mix the back and carry out ultramicro grinding with airslide disintegrating mill, obtain 800 orders～1000 order fine powders.
2) mix in the aqueous solution adding blender with gained fine powder and adhesive,,, promptly obtain the water dispersant granula of this pesticide species 50 ℃～100 ℃ following low temperature dryings through the oscillating granulator granulation.
Good effect of the present invention is as follows: the epoxiconazole water decentrality granula that adopts prescription of the present invention to process, its implementation result shows, this product has reduced peasant's use cost, reduced pollution to environment, and have in the use of the present invention that content height, disintegration are fast, good dispersion, little, the easy to use, safe coefficient height of environmental pollution, pollution-free to the crop blade face, can promote the photosynthesis of crop, human body do not had characteristics such as injury, and packing is simple, storing is convenient, belongs to science environmental protection formulation product.
