Description

Anilofos and pyrazosulfuron water surface diffusant and preparation method thereof

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, pyrazosulfuron single dose and combination dosage forms thereof have missible oil, wettable powder, granule, water dispersible granules at present, and these formulations need be watered spraying or pesticide-clay mixture while use, time-consuming taking a lot of work, and labor intensity is large. Wettable powder, missible oil produce and use procedure in easily cause drift, contaminated environment and 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 the full field advantage of diffusion automatically, greatly reduces labour intensity. Be particularly suitable for the area of lack of labor. At present, realize suitability for industrialized production except there are minority kind in the U.S., Japan, other countries are still in conceptual phase. China had studied some solid water surface float type agricultural chemicals and spread the liquid preparations such as drops, but ubiquity because of diffusion velocity and the not good pesticide activity component causing of diffusion radius and disperse unequal deficiency, failed so far spread.

The inventor studies anilofos and pyrazosulfuron, by its combination and be prepared into water surface diffusant, for preventing and kill off rice terrace annual grassy weeds.

Summary of the invention

The object of the present invention is to provide a kind of stable performance, suspensibility is high, the anilofos of reliable in quality and pyrazosulfuron water surface diffusant.

Another object of the present invention is to provide the preparation method of above-mentioned water surface diffusion.

Technical scheme: a kind of for preventing and kill off the floating particle agent of paddy field weed, it is made up of the component of following percentage by weight: 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%, 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, alkylpolyoxyethylene phosphate or alkyl naphthalene formaldehyde condensate sulfonates.

Described wetting agent is selected neopelex, is pulled open powder, one or more mixing in 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, pungent certain herbaceous plants with big flowers acid methyl esters.

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 sulfate, calcium chloride, sodium chloride, magnesium chloride.

Described density adjuster is selected one or more the mixing in white carbon, pregelatinized starch, superfine silica gel powder, potassium chloride.

Described carrier is selected one or more the mixing in kaolin, potter's clay, attapulgite, diatomite, perlite, silica gel, hollow glass bead, sawdust powder, corncob.

Described binding agent is selected one or more the mixing in dextrin, starch, white sugar, glucose.

Described is a kind of for preventing and kill off the floating particle agent of paddy field weed, its preparation method: by 1%-60% anilofos and pyrazosulfuron, 1%-15% water surface diffusion auxiliary agent, 0.5%-10% dispersant, 0.1%-5% wetting agent, 1%-10% disintegrant, 1%-10% density adjuster, after appropriate carrier mixes, adds 1%-10% binding agent to make moist wood, then adopt extruding or eddy flow fluidization granulation, drying just forms product.

In recent years, because rural laborer goes down town and works in a large number, cause labour's famine, adopt traditional application method, take time and effort, and dispenser personnel are easily poisoning. The floating particle agent that the present invention is made, has very strong spontaneous diffusivity, selects several points to drop into agricultural chemicals in field, can spontaneously diffuse to full field completely, and pesticide supplying effect is not affected by external condition.
