Abstract
A bromothalonil water dispersible granule and a preparation method thereof and belongs to the technical field of pesticides. The bromothalonil water dispersible granule comprises the following components in percentage by weight: 30%-70% of bromothalonil, 1%-15% of a dispersing agent, 1%-15% of a wetting agent, 1%-15% of a binder, 1%-15% of a stabilizer, 1%-15% of a disintegrating agent, 1%-5% of a penetrating agent and the rest of packing. The preparation method comprises the steps of: firstly uniformly mixing the bromothalonil with the dispersing agent, the wetting agent, the binder, the stabilizer, the disintegrating agent, the penetrating agent and the packing, and carrying out air powder processing; then watering and kneading; and finally pelleting and drying. The bromothalonil water dispersible granule has powerful internal absorption and seepage force and can kill pathogenic bacteria intruding into plant bodies; the good effect can be achieved by using the low-concentration bromothalonil water dispersible granule; and the bromothalonil water dispersible granule has the quick-acting and persistent effects and the long-term advantageous effect can be kept.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of bactericide water dispersible granule and preparation method thereof.
Background technology
Bromothalonil is the bactericide of a kind of wide spectrum, efficient, low toxicity, and chemical formula is C6H6Br2N2, and molecular weight is 265.94.Bromothalonil can suppress and root out the growth of fungi, bacterium, algae, and corps diseases is had preferably control efficiency, and anthracnose is had special efficacy.Be widely used in the various crop such as fruit tree, grape, vegetables, cotton, peanut, watermelon, tobacco, tea tree, flowers, prevent and treat multiple fungoid, the bacteroidal diseases such as anthracnose, scab, shot hole, powdery mildew, rust, damping off, damping off, rhizome maize ear rot, canker, bacterial wilt, angular leaf spot.Application mode is flexible, and foliar spray, seed treatment and soil are filled with root, all show preferably preventive effect.
At present, mainly contain bromothalonil wetting powder, two kinds of formulations of missible oil on the market, but these two kinds of formulations are still having deficiency aspect quick-acting, lasting effect, the environmental protection, all have the problems such as drug effect is not good, need to use the bromothalonil of larger dose just can reach the purpose of sterilization.And the used solvent of Traditional Agricultural pharmaceutically dosage form missible oil (Emulsifiable Concentrate, EC) mainly is the aromatic hydrocarbon substances such as toluene and dimethylbenzene, has also wasted a large amount of petroleum resources in the time of contaminated environment.Therefore, progressively cut down the missible oil product, promote the use of the environmental protection type agricultural chemical formulation and become as the main trend of at present formulations of pesticide development take the requirement that meets agricultural sustainable development.
Summary of the invention
The objective of the invention is for top described defective, provide wide, quick-acting good, the holding effect of a kind of fungicidal spectrum long bromothalonil water dispersible granules.
Another object of the present invention provides a kind of preparation method of bromothalonil water dispersible granules.
A kind of bromothalonil water dispersible granules is characterized in that, is made by the component of following percentage by weight: bromothalonil 30%-70%, dispersant 1%-15%, wetting agent 1%-15%, binding agent 1%-15%, stabilizing agent 1%-5%, disintegrant 1%-15%, bleeding agent 1%-5%, filler complementary.
Described dispersant is selected from sodium lignin sulfonate, calcium lignosulfonate, lauryl alcohol polyethylene glycol oxide base ether sodium sulfate, Fluhyzon formaldehyde condensation products iodate, potassium oleate, enuatrol, alkylphenol polyoxyethylene, naphthalenesulfonic acid-formaldehyde condensate, triphenyl vinyl phenol polyethenoxy ether class and derivative fat, fatty alcohol polyethenoxy ether class, the alkylphenol polyoxyethylene class, macromolecule EO-PO block copolymer, macromolecule is dredged a dress copolymer of type, the polymerization of carboxylic acid salt, dispersing agent MF, alkylphenol-polyethenoxy formaldehyde condensation products sulphate, in the styrene phenol polyoxyethylene phosphonate one or more.
Described wetting agent is selected from one or more in lauryl sodium sulfate, neopelex, sldium lauryl sulfate, octyl phenol polyoxy vinyl formal condensate sulfate, alkylnaphthalene sulfonate or the alkyl fourth disulfonate.
Described binding agent is selected from one or more in PVOH 2000-6000, glucose, lactose, ethylene glycol, propane diols or the glycerine.
Described disintegrant is selected from one or more in potash, sodium carbonate, sodium bicarbonate, carbonic hydroammonium, ammonium sulfate, glauber salt, ammonium nitrate or the urea element.
Described bleeding agent is ethyoxyl modification trisiloxanes or azone.
Described filler is selected from one or more in diatomite, water-washed kaoline, bentonite, white carbon, corn starch, the soluble starch.
Described stabilizing agent is one or more in citric acid, monoxone or the lactic acid.
A kind of preparation method of bromothalonil water dispersible granules is characterized in that, first bromothalonil and dispersant, wetting agent, binding agent, stabilizing agent, disintegrant, bleeding agent, filler is mixed, and the gas powder adds water again and mediates, and last granulation is also dry.
The invention has the beneficial effects as follows: the present invention has powerful interior suction, penetration, can kill the pathogen in the invaded plants body, uses low concentration just can obtain high effect, has quick-acting and lasting effect, can keep long-term superior effect.
