Abstract
The invention relates to a difenoconazole and propiconazole suspension concentrate emulsion. The difenoconazole and propiconazole suspension concentrate emulsion has the advantages of simple production technology, easy operation, stable product quality, good dispersibility and malleability, strong adhesion capacity on the surface of a plant body, rain wash resistance and obvious and lasting pharmaceutical effect.
Description
Technical field
The present invention relates to a kind of pesticidal preparations, relate in particular to a kind of methyl sulcotrione oil suspension concentrate combination.
Background technology
Being applied to now Difenoconazole. the methyl oleate of propiconazole water in suspension emulsion solvent is because source is unstable, and part producer has also added some animal raw fat compositions therein therein, cause methyl oleate quality unstable, under cryogenic conditions, there are a large amount of solidss to analyse and cause the huge increasing of viscosity of solvent, and then affected normally carrying out of production and processing, while carrying out production and processing in the winter time, must in drying room, will after methyl oleate bakingization, just can feed intake, during consumption energy consumption.
Summary of the invention
The present invention is directed to above-mentioned defect, object is to provide the main skill of a kind of production fairly simple, easy operating, constant product quality, dispersiveness and plate-out ability are good, the ability that sticks to plant corpus surface is more intense, resistance of rainwater washing against, a kind of Difenoconazole that drug effect is more remarkable and lasting. propiconazole water in suspension emulsion.
The technical solution used in the present invention is for this reason: its component and percentage by weight are:
| Difenoconazole | 15%~18% |
| Propiconazole | 15%~18% |
| Dimethyl carbonate solvent | 5%~10% |
| Emulsifying dispersant | 5%~ 10% |
| Plant growth regulator | 0.01~0.5% |
| Antifreezing agent | O%~5.0% |
| Thickener | 0%~2.0% |
| Deionized water | Benefit to 100.00% |
Described emulsifier is the mixture of many phenol polyoxyethylene polyoxypropylene block polymerization phosphate triethanolamine salt and castor oil polyoxyethylene base ether.
Described thickener is aluminium-magnesium silicate or xanthans.
Described antifreezing agent is urea.
Described plant growth regulator is diethylamino ethanol caproate.
Dimethyl carbonate (Dimethyl Cabonate) abbreviation DMC is a kind of water white transparency during normal temperature, omit scent of, micro-sweet liquid, 4 ℃ of fusing points, 90.1 ℃ of boiling points, density 1.069 g/cm3, are insoluble in water, but immiscible organic solvent that can be nearly all with alcohol, ether, ketone etc.DMC under normal pressure and methanol azeotropic, 63.8 ℃ of azeotropic temperatures.DMC toxicity is very low, in 1992, just by Europe, classified as nontoxic product, it is a kind of environmental protective type chemical raw material that the modern times " cleaning procedure " require that meets, DMC has good solubility property, and it is molten, boiling spread is narrow, and surface tension is large, viscosity is low, medium circle electric constant is little, has higher evaporating temperature and evaporation rate faster simultaneously, therefore can be used as low poison solvent for coatings industry and pharmaceuticals industry.DMC not only toxicity is little, also have that flash-point is high, steam forces down with air in LEL high, be therefore the green solvent that integrates spatter property and safety.
Advantage of the present invention is: 1) dimethyl carbonate solvent is more single than the conventional methyl oleate composition in present oil-suspending agent, and good fluidity is lower than the viscosity of methyl oleate at low temperatures, during as oil-suspending agent processing batching, viscosity is little, grinding resistance is little, and energy consumption is little, and efficiency is high; 2) price of dimethyl carbonate and the cost of methyl oleate are similar at present, and more much lower than the cost of soybean oil rapeseed oil or peanut oil, operation technique is similar with other solvents.And the molecular weight of dimethyl carbonate is less, than other common easier emulsification of grease kind solvent, emulsification better effects if under identical emulsifier, drug effect is better.In the present invention simultaneously, emulsifier castor oil polyoxyethylene base ether contains two key unsaturated hydrocarbon, and castor oil polyoxyethylene base ether can effectively reduce oxidation and the decomposition amount of suspending agent in hot conditions, thereby guarantees that product is in the stability of storing of high temperature season.
