The tribenuron-methyl oil flowable concentrale comprises the following components in parts by weight: 1-35 parts of tribenuron-methyl technical product, 10-45 parts of wetting dispersant, 0.5-10 parts of penetrating agent, 0.1-2 parts of thickener, 0.5-5 parts of antifreezing agent, 0.1-5 partsof defoaming agent and the balance dispersion medium.
Description
Technical field
The invention belongs to herbicide technology field, more particularly relate to a kind of novel tribenuron-methyl oil flowable concentrale and preparation method thereof.
Background technology
Tribenuron-methyl general by name, (acid was tribenuron; Methyl esters is tribenuron-methyl), chemical name is 2-[4-methoxyl group-6-methyl isophthalic acid, 3,5-triazine-2-base (methyl) carbamyl amino-sulfonyl] benzoic acid or methyl esters.Tribenuron-methyl is a selective herbicide behind the sulfonylurea inner sucting conduction type bud, can be after cauline leaf is handled by weeds cauline leaf, root absorption, and conduction in vivo, by hindering acetolactate synthestase, the biosynthesis of valine, isoleucine is suppressed, stop cell division, cause weeds death.Broadleaf weed chickweed, shepherd's purse, conical silene herb, corn gromwell, ion grass, clearvers, Hairy Bittercress, Stellaria alsine Grim., volume stem knotweed etc. are to the tribenuron-methyl sensitivity, medium sensitivities such as wartwort, Veronica.Observed weeds in 10-14 days after the dispenser and be subjected to the severe inhibition effect, lobus cardiacus moves back green necrosis gradually, and blade moves back green, and generally whole gradually strain in 30 days is withered behind the winter wheat medicine, and dead plant strain growth is suppressed, and acts on slower.Anti-heterodynes such as field bindweed, Commelina communis, acalypha copperleaf, Armstrong, field thistle strengthen with dosage rising inhibitory action.Tribenuron-methyl has good drug resistance to cereal crop.
The floating agent of pesticide oil suspension is solid pesticide or the dispersion of immiscible liquids agricultural chemicals in oil that is insoluble to oil, consider from the production angle, generally require former medicine at room temperature to be solid, and the solvability in dispersion medium (20 ℃～40 ℃) is lower than the pesticide species of 100mg/L.The advantage of the floating agent of pesticide oil suspension is evenly to mix dispersion with arbitrary proportion with oil, and is easy to use, is difficult for contaminated environment, can directly or after the dilution spray.Preparation for processing can be made the suspension of high dispersive, continuous phase by waterproof pulverization, and the average grain diameter of its particle has improved the suspensibility of particle in aqueous medium greatly generally below 3 microns, has strengthened the absorption of crops to medicament.
Present tribenuron-methyl preparation mostly is wetting powder.Publication number is that the Chinese patent of CN1408229 discloses a kind of soluble tribenuron-methyl powder and method for making thereof, and its technical essential is its raw material components and percentage by weight thereof: the mixture of the mixture of 1～50% tribenuron-methyl, 30～75% urea, amine fertilizer or urea and amine fertilizer, 6～25% sodium lignin sulfonates, 11～33% Anhydrous potassium carbonates (sodium), Carbon Dioxide hydrogen potassium (sodium) or Anhydrous potassium carbonate (sodium) and Carbon Dioxide hydrogen potassium (sodium).Do not have independent report at present in the prior art at tribenuron-methyl oil flowable concentrale and concrete prescription and preparation method, the application is through studying for a long period of time, provide a kind of under the prerequisite that guarantees drug effect, can effectively reduce environmental pollution and save tribenuron-methyl oil flowable concentrale prescription of production and use cost and preparation method thereof.
Summary of the invention
One of goal of the invention of the present invention has just provided a kind of tribenuron-methyl oil flowable concentrale.
Another object of the present invention is to provide the preparation method of above-mentioned tribenuron-methyl oil flowable concentrale.
The technical solution used in the present invention is:
A kind of tribenuron-methyl oil flowable concentrale is characterized in that, is made by following components in weight percentage:
The former medicine 1～35 of tribenuron-methyl
Wetting dispersing agent 10～45
Bleeding agent 0.5～10
Thickener 0.1～2
Antifreezing agent 0.5～5
Defoamer 0.1～0.5
Surplus is a dispersion medium;
Described wetting dispersing agent is one or more in alkylphenol polyoxyethylene, phenethyl phenol polyethenoxy ether, alkyl phenol formaldehyde resin polyoxyethylene ether, alkylaryl polyoxyethylene poly-oxygen propylene aether, alkylphenol polyoxyethylene sulfosuccinate, aliphatic alcohol polyoxyvinethene phosphate and the polyoxyethylene nonylphenol ether phosphate;
Described bleeding agent is one or more in JFC, fast penetrant T, the azone, is the commercial goods, and supplier is a Shanghai Tiantan Accessory Ingredient Co., Ltd;
Described thickener has a kind of or any two kinds of mixtures in gum Arabic, xanthans, methylcellulose, carboxymethyl cellulose, hydroxyethylcellulose, PAA, polyvinyl alcohol, white carbon, bentonite, the aluminium-magnesium silicate;
Described antifreezing agent is a kind of or any two kinds of mixtures in ethylene glycol, urea, propane diols, the glycerine;
Described defoamer has a kind of in n-octyl alcohol, the silicone defoaming agent;
Described dispersion medium is mineral oil, vegetable oil (for example soybean oil, corn wet goods) or vegetable oil resin (for example rape-seed oil methyl ester) etc.
Above-mentioned tribenuron-methyl oil flowable concentrale, preferably make by following components in weight percentage:
The former medicine 1～25 of tribenuron-methyl
Wetting dispersing agent 20～40
Bleeding agent 0.5～10
Thickener 0.1～2
Antifreezing agent 0.5～5
Defoamer 0.1～0.5
Surplus is a dispersion medium.
The method for making of described tribenuron-methyl oil flowable concentrale comprises the steps:
1) in mixing kettle, adds the former medicine of tribenuron-methyl, wetting dispersing agent, bleeding agent, thickener, antifreezing agent, defoamer and dispersion medium, under high shear is stirred, material is fully mixed;
2) above-mentioned material is squeezed in the sand mill ground, grind till 2～4 microns of average grain diameters;
3) check, qualified back packing.
Compare with the existing product technology, the present invention has following beneficial effect:
1) oil-suspending agent is to be solvent with mineral oil, vegetable oil (for example soybean oil, corn wet goods) or vegetable oil resin (for example rape-seed oil methyl ester) etc., compare dry suspending agent and wetting powder product, has many-sided advantage: strengthen affinity with crop, improve the wax coat that pesticide active ingredient penetrates plant epidermis, prolong the residual effect on blade face, the wax coat of dissolving epidermis; Reduce evaporation; Strengthen penetration; Strengthen medicament in the adhesivity of crop surface etc.These advantages are that products such as dry suspending agent and wetting powder are not available, and this helps the plant absorption, helps drug effect to give full play to.
2) after formulation changed, dosage reduced, and drug effect improves, and has reduced peasant's drug cost.
3) because comminution by gas stream (dry type comminuting method) is adopted in the processing of pulvis and granula product more, the fineness of product is generally about 44 μ m, and the oil suspending agent product adopts sand mill (case of wet attrition method), the fineness of product is generally about 4 μ m, product fineness is high more, the suitable more absorption of weeds is so the oil suspending agent effect will be better than pulvis and granule far away.
