Abstract
The invention discloses difenoconazole containing water dispersible granule and a preparation method thereof. The difenoconazole containing water dispersible granule comprises, by weight, 10%-70% of raw difenoconazole, 1%-5% of a wetting agent, 1%-10% of the granule, 1%-10% of a disintegrating agent and complement of a carrier of packing. The preparation method includes: subjecting raw components to mixing and ultramicro airflow grinding and obtaining finished products via kneading prior to extruding and pelletizing, drying, screening and packaging. The difenoconazole containing water dispersible granule and the preparation method thereof have the advantages that the difenoconazole containing water dispersible granule is low in cost, simple in preparation process, low in packaging demand and small in environmental pollution, control efficiency is improved by selectively use of synergistic effect of the specific wetting agent and granule and is higher than that of a difenoconazole suspending agent, application dosage can be reduced, and the difenoconazole is suitable for extensively promotion and application.
Description
Technical field
The present invention relates to a kind of pesticidal preparations and preparation method thereof, the water-dispersible grain of a kind of Difenoconazole
Agent and preparation method thereof.
Background technology
Difenoconazole is that in triazole bactericidal agent, safety is higher, and model of action is the sterilization of interior absorption, tool protection
And therapeutical effect, be widely used in the crop such as fruit tree, vegetable, effectively prevent and treat scab, anthrachose of grape, white rot, spot defoliation,
Powdery mildew, brown spot, rust, stripe rust, head blight etc..Fungicidal spectrum is wide, to Ascomycetes, Basidiomycetes with include rod method
Genus, Ascochyta, Cercospora, Colletotrichum, ball Cuo Pseudomonas, Phoma, Ramularia, Septoria, Venturia exist
Interior partly knows disease, and Erysiphaceae, Uredinales and some Seedborne pathogen have lasting protection and therapeutical effect.To Fructus Vitis viniferae anthrax
Disease, white rot effect are also fine, and in soil, mobility is little, can slowly degrade.
The advantage being fabricated to Difenoconazole water-dispersible granules is: 1. without organic solvent, greatly reduces environment
Pollute；There is no dust from flying during sprinkling, to operator's safety, decrease the pollution to environment；2. active constituent content is high, adds
Auxiliary agent few, product is relatively denser, volume packaging little, easy, easily storage and transport, has the strongest economic benefit and society's effect
Benefit；3. physical and chemical stability is good, particularly unstable in water pesticide, after making water dispersible granules, more stable；4. water is entered
Easy disintegrating, good dispersion, suspensibility is high, and drug effect is high.5. good fluidity, does not glue wall, packs disposable；6. safety is good and ring
Border is compatible.
Summary of the invention
It is an object of the invention to provide a kind of efficient, low toxicity and the lasting period is long, for pear scab, Fructus Mali pumilae speckle fallen leaves
Disease, Fructus Lycopersici esculenti drought epidemic disease, watermelon grafting, pepper anthracnose, powdery mildew of strawberry, bitter rot or anthracnose of grape, anthrachose of grape, citrus scab etc.
All there is the difenoconazole water dispersible granule of preferable therapeutic effect.
The technical solution adopted in the present invention is: a kind of water dispersible granules containing Difenoconazole, including effective active
Composition Difenoconazole, wetting agent, dispersant, disintegrating agent and filler, each weight percentages of components is: effective active composition benzene
Ether methyl cyclic-azole 10%～70%, wetting agent 1%～5%, dispersant, 1%～10%, disintegrating agent 1%～10%, filler is supplied.
Described wetting agent is selected dodecylbenzene sodium sulfonate, is pulled open powder, alkyl phenol formaldehyde resin polyoxyethylene ether sulphuric acid
The mixing of one or more in salt, alkylphenol-polyethenoxy base ether, Nonyl pheno base ether.
Described dispersant selects sodium lignin sulfonate, polycarboxylic acid salt, lauryl alcohol polyethylene glycol oxide base ether sodium sulfate, alkyl
Naphthalene formaldehyde condensate sulfonates, alkyl polyoxyethylene ether sulfonate, alkylphenol-polyethenoxy base ether formaldehyde condensation products, polyoxyethylene
The mixing of one or more in polyoxypropylene base ether block copolymers, alkylpolyoxyethylene phosphate ester.
One or more in ammonium sulfate, sodium sulfate, carbamide, carboxymethyl starch sodium, glucose selected by described disintegrating agent
Combination.
Described carrier filler is the one or more combination in Kaolin, kieselguhr, fine particle calcium carbonate, corn starch, bentonite.
The preparation method is that: the mixing such as the above-mentioned former medicine of each component, wetting agent, dispersant, disintegrating agent, filler are stirred
Mix, be crushed to required fineness through micro jet, by extruder grain drying after kneading, screen out qualified particle diameter
Grain semi-finished product, pack and i.e. obtain water dispersible granules.
The antibacterial that the present invention provides has the advantages that.
1, the antibacterial that the present invention provides, shows obvious potentiation in certain ratio range, and prevention effect has
Significantly improve, reduce the using dosage of pesticide, decrease the pesticide impact on environment, reduce drug cost.
2, the antibacterial that the present invention provides, practical, in pear scab, alternaria leaf spot of apple, Fructus Lycopersici esculenti drought epidemic disease, west
Melon blight dis-ease, pepper anthracnose, powdery mildew of strawberry, bitter rot or anthracnose of grape, anthrachose of grape, citrus scab etc. all have preferably treats effect
Really.
3, the antibacterial that the present invention provides, has protection and therapeutical effect.
