Technical field
The present invention relates to the method for composition pesticide and preparing product, particularly the method for water-dispersible granules agricultural compositions and preparing product.
Background technology
At present, China's pesticide species and formulation are all a lot, how to occur with emulsifiable concentrate and wetting powder formulation.Because the missible oil formulation is used a large amount of organic benzene-like compounds, wetting powder in process of production, exist the drug dust in production and the farmland dispenser to be easy to the severe contamination that causes of operating personnel and ecotope is endangered, and the plant effective rate of utilization is low, the residue of pesticide time is long, easy-clear not again has defectives such as certain influence to the physical and mental health of numerous people.
Summary of the invention
The purpose of this invention is to provide a kind of nonhazardous, pollution-free, production technology is simple, and cost is low, and is easy to use, operator ' s health is not had injury and environmentally safe, improved the water-dispersible granules agricultural compositions of the rate of dispersion of medicine in water simultaneously greatly.
Another object of the present invention provides a kind of method of preparing product.
In order to overcome the deficiencies in the prior art, solve technical scheme of the present invention and be achieved in that a kind of water-dispersible granules agricultural compositions, its outstanding progress is that the bulk drug effective ingredient can be above-mentioned a kind of of azacyclotin, anthrax good fortune U.S., meta-tolyl-N-methylcarbamate (MTMC), triazolone, Tebuconazole, own azoles alcohol, Mobucin, Buprofezin, fenbutatin oxide, butyl ether urea, pyridaben, and this composition pesticide is shaped as rule or irregular coccoid; Its composition pesticide composition is as follows by mass ratio:
Bulk drug: 100 parts~850 parts
Auxiliary agent: 1 part~250 parts
Carrier: 10 parts~550 parts
Wherein said bulk drug comprises that azacyclotin, anthrax good fortune U.S., meta-tolyl-N-methylcarbamate (MTMC), triazolone, Tebuconazole, own azoles alcohol, Mobucin, Buprofezin, fenbutatin oxide, butyl ether urea, pyridaben are one kind of;
Described auxiliary agent, can be sodium alkyl sulfate, polycarboxylic acids sodium, alkylphenol polyoxyethylene, fatty alcohol-polyoxyethylene ether, sulfite cellulose solid dry substance, naphthalene sulfonic acid-formaldehyde condensation product, oxirane propylene oxide block copolymer, starch, Macrogol 6000, Tween-60, sodium alkyl benzene sulfonate, sodium carboxymethylcellulose, Tween-80, silicone defoamer, one of them and combination;
Described carrier can be one of them or combination wherein of urea, calcium monohydrogen phosphate, ammonium sulfate, kaolin, white carbon, bentonite and diatomite;
The method for preparing claim 1 product, undertaken by following step:
I, according to the purposes that will prepare the water dispersant granule pesticide, accurately take by weighing above-mentioned a kind of bulk drug, one or both or two or more auxiliary agents, one or both or two or more carriers, after mixing, carry out ultramicro grinding, obtain 500 orders~800 order fine powders with airslide disintegrating mill;
II, the aqueous solution of gained fine powder and binding agent added in the blender mix, through the oscillating granulator granulation, 50~80 ℃ of following low temperature dryings promptly obtain the water dispersant granula of different cultivars agricultural chemicals.
The present invention compared with prior art, it is simple to have production technology, cost is low, easy to use, operator ' s health there are not the injury and the characteristics of environmentally safe, the present invention is owing to having taked the air-flow superfine communication technique, the granularity of the medicinal powder after the pulverizing is very little generally more than 500 orders, make the specific surface area of raw material increase thousands of times, added surfactant simultaneously, improved active component, higher suspension rate, high bioactivity, safe in utilization; Have the good dispersiveness and the characteristics of storage-stable, make the bioavailability of effective ingredient improve greatly, make the dispersity of effective ingredient in water be greatly enhanced, disintegration rate is accelerated, and effectively improves drug effect.Adjuvant used, carrier is nonhazardous, pollution-free simultaneously, reduced pollution to environment and operating personnel, be widely used in preventing and treating anthracnose, brassicaceous vegetable diamond-back moth, the rice hoppers of mandarin tree two spotted spider mite, powdery mildew of cucumber, citrus red mite, pear scab, apple tree, the damage by disease and insect of apple tree two spotted spider mite, effect is very remarkable.
