Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of anilofos and pyrazosulfuron water surface diffusant and preparation method thereof.
Background technology
Anilofos, the agent of pyrazosulfuron list and combination dosage forms thereof have missible oil, wettable powder, granule, water dispersible granules at present, need convert water spray or pesticide-clay mixture when these formulations are used, time-consuming taking a lot of work, and labor intensity is big.Wetting powder, missible oil easily cause drift in production and use, contaminated environment reaches the producer is endangered.
Water surface diffusant is a kind of very new formulations of pesticide.It and traditional agricultural chemicals have greatest differences, have a dispenser, and full field is the advantage of diffusion automatically, greatly reduces labour intensity.Be particularly suitable for the area of lack of labor.At present, except having the minority kind, the U.S., Japan realizes that other countries still are in conceptual phase the suitability for industrialized production.China had studied some solid water surface float type agricultural chemicals and had spread liquid preparation such as drops, but ubiquity because of diffusion velocity and the not good pesticide activity component that causes of diffusion radius and disperse unequal deficiency, failed large tracts of land so far to promote.
The inventor studies anilofos and pyrazosulfuron, with its combination and be prepared into water surface diffusant, is used for preventing and kill off the paddy field annual weed.
Summary of the invention
The object of the present invention is to provide a kind of stable performance, suspensibility height, reliable quality anilofos and pyrazosulfuron water surface diffusant.
Another object of the present invention provides the preparation method of above-mentioned water surface diffusion.
Technical scheme: a kind of be used to the floating particle agent of preventing and kill off paddy field weed, it is made up of following components in weight percentage: anilofos and pyrazosulfuron total content 1%-60%, water surface diffusion auxiliary agent 1-15%, dispersant 0.5%-10%, wetting agent 0.1%-5%, binding agent 1-10%, disintegrant 1-10%, density adjuster 1-10%, the carrier surplus.The mass ratio of anilofos and pyrazosulfuron is 50:1-1:20.
Described dispersant is selected one or more the mixing in sodium lignin sulfonate, lignin calcium iodate, polycarboxylic acid salt, alkyl naphthalene formaldehyde condensate sulfonates, alkylphenol-polyethenoxy base ether formaldehyde condensation products, polyoxyethylene polyoxypropylene base ether block copolymers, dodecyl polyoxyethylene ether phosphate or the alkyl naphthalene formaldehyde condensate sulfonates for use.
Described wetting agent is selected neopelex for use, is drawn back powder, one or more the mixing in the lauryl sodium sulfate, alkylphenol-polyethenoxy base ether Nonyl pheno base ether, the fast T of wetting and penetrating agent.
Described water surface diffusant is selected one or several the mixing in refining mineral oil, saxol, white spirit, peanut oil, soybean oil, palm oil, turpentine oil, the hot certain herbaceous plants with big flowers acid methyl esters for use.
Described disintegrant is selected one or more the mixing in microcrystalline cellulose, sodium carboxymethyl starch, water soluble starch, sodium sulphate, ammonium sulfate, urea, potassium chloride, potassium sulphate, calcium chloride, sodium chloride, the magnesium chloride for use.
Described density adjuster is selected one or more the mixing in white carbon, pregelatinized starch, superfine silica gel powder, the potassium chloride for use.
Described carrier is selected one or more the mixing in kaolin, potter's clay, attapulgite, diatomite, perlite, silica gel, hollow glass bead, sawdust powder, the corncob for use.
Described binding agent is selected one or more the mixing in dextrin, starch, white sugar, the glucose for use.
Described a kind of be used to the floating particle agent of preventing and kill off paddy field weed, its preparation method: with 1%-60% anilofos and pyrazosulfuron, 1%-15% water surface diffusion auxiliary agent, 0.5%-10% dispersant, 0.1%-5% wetting agent, the 1%-10% disintegrant, the 1%-10% density adjuster after an amount of carrier mixes, adds the 1%-10% binding agent and makes moist wood, adopt extruding or eddy flow fluidization granulation then, drying just forms product.
In recent years, because the rural laborer goes down town in a large number and works, cause labour's famine, adopt traditional application method, take time and effort, and the dispenser personnel poison easily.The floating particle agent that the present invention is made has very strong spontaneous diffusivity, selects several points to drop into agricultural chemicals in the field, can spontaneously diffuse to full field fully, and pesticide supplying effect is not influenced by external condition.
