Abstract
The present invention discloses a pyraclostrobin nano-preparation which can improve the application effect of the pyraclostrobin, decrease pyraclostrobin usage amount, and reduce the cost of production of crops, and a preparation method thereof. The preparation method comprises the following steps: dissolving the pyraclostrobin powder in distilled water, and magnetic stirring at 900r/min for 20min, wherein the usage ratio of the pyraclostrobin powder to distilled water is 10mg: 100ml; adding sodium dodecyl sulfate into the pyraclostrobin solution and magnetic stirring at a rotational speed of 900r/min for 20min, wherein the usage ratio of the sodium dodecyl sulfate to the pyraclostrobin solution is 5mg: 100ml; and treating the obtained solution with ultrasonic vibration of a frequency of 40KHz for 2 hours.
Description
Technical field
The present invention relates to inhale in a kind of broad spectrum activity the low toxicity bactericide, especially a kind of effect that improves pyraclostrobin, reduce the pyraclostrobin usage amount, reduce the crops production cost pyraclostrobin nanometer formulation and preparation and purposes.
Background technology
Pyraclostrobin has another name called pyraclostrobin, chemical name: methyl (N)-[[[1-(4-chlorobenzene) pyrazoles-3 base)-oxygen]-the 0-methoxyl group]-the N-methoxymethyl carbamate, molecular formula: C19H18ClN3O4.
Pyraclostrobin is wide-spectrum bactericide, has permeability and local systemic activity, and the lasting period is long, and the resistance of rainwater washing against characteristics reach protection, treatment, blade infiltration conduction.Be widely used in preventing and treating wheat, paddy rice, peanut, grape, vegetables, potato, banana, lemon, coffee, fruit tree, walnut, tea tree, tobacco and ornamental plants etc.For the large stigma of control of maize, powdery mildew of cucumber, downy mildew and banana freckle, leaf spot etc. better effects is arranged.
Nanometer technology is in the mechanism of 1 ~ 100nm yardstick research material and the cutting edge technology of character, its final goal is the product that has specific function with the characteristic manufacturing on nanoscale of molecule, atom and material, but up to now, also less than the relevant report about the pyraclostrobin nanometer formulation.
Summary of the invention
The present invention is in order to solve the existing above-mentioned technical problem of prior art, a kind of effect that improves pyraclostrobin to be provided, reducing pyraclostrobin nanometer formulation and the preparation method of the production costs such as pyraclostrobin usage amount, reduction crops.
Technical solution of the present invention is: a kind of preparation method of pyraclostrobin nanometer formulation is characterized in that carrying out according to the following steps successively:
A. the pyraclostrobin pulvis is mixed with distilled water, 900r/min magnetic agitation 20min makes pyraclostrobin solution, and the amount ratio of pyraclostrobin pulvis and distilled water is 10mg:100ml;
B. dodecyl sodium sulfate is added in the pyraclostrobin solution with rotating speed 900r/min magnetic agitation 20min, the amount ratio of dodecyl sodium sulfate and pyraclostrobin solution is 5mg:100ml;
C. be the ultrasonic oscillation 2 hours of 40KHz with gained solution frequency.
The pyraclostrobin nanometer formulation a kind of as preparation method above-mentioned pyraclostrobin nanometer formulation prepares.
Preparation method of the present invention is simple, and prepared pyraclostrobin nanometer formulation granularity is comparatively even, good dispersion.Pyraclostrobin is played a role at nanometer level, not only kept the bactericidal action of pyraclostrobin, and strengthen its action effect, reduce the pyraclostrobin usage amount, reduced the production cost of crops.
Description of drawings
Fig. 1 is 100k times of SEM figure of pyraclostrobin nanometer formulation of the embodiment of the invention.
Fig. 2 is 1k times of SEM figure of pyraclostrobin solvent.
Embodiment
Embodiment 1:
Carry out according to the following steps successively:
A. weigh and be purchased from Shandong sea and pyraclostrobin pulvis that three sharp biochemical industry Co., Ltds produce is dissolved in the distilled water, with constant temperature blender with magnetic force with 900r/min magnetic agitation 20min, the pyraclostrobin solution of making;
B. dodecyl sodium sulfate is added in the pyraclostrobin solution, with rotating speed 900r/min magnetic agitation 20min, the amount ratio of dodecyl sodium sulfate and pyraclostrobin solution is 5mg:100ml with constant temperature blender with magnetic force again;
C. be the ultrasonic oscillation 2 hours of 40KHz again with gained solution frequency, namely make the pyraclostrobin nanometer formulation.
The type of used supersonic wave cleaning machine is JCP-1004.
Pyraclostrobin nanometer formulation and former pyraclostrobin solvent that the present invention makes are observed such as Fig. 1,2 under SU8010 type SEM.As can be seen from the figure nano particle diameter is to dwindle 1000 times than original reagent particle size between 50 ~ 100nm, and can find out that phase is pure, and free from admixture exists.
Can with gained pyraclostrobin nanometer formulation distilled water constant volume, obtain the pyraclostrobin nanometer formulation of variable concentrations, such as 0.1g/L, 0.4g/L, 1g/L.
Under light microscope, can observe, concentration is that 1g/L pyraclostrobin distribution of particles is the most even in three kinds of concentration, the highest effect of particle nanorize degree is best, and concentration is that the pyraclostrobin effect of 0.4g/L is taken second place, and concentration is that pyraclostrobin effect in three kinds of concentration of 0.1g/L is the poorest.
Claims (2)
1. the preparation method of a pyraclostrobin nanometer formulation is characterized in that carrying out according to the following steps successively:
A. the pyraclostrobin pulvis is mixed with distilled water, 900r/min magnetic agitation 20min makes pyraclostrobin solution, and the amount ratio of pyraclostrobin pulvis and distilled water is 10mg:100ml;
B. dodecyl sodium sulfate is added in the pyraclostrobin solution with rotating speed 900r/min magnetic agitation 20min, the amount ratio of dodecyl sodium sulfate and pyraclostrobin solution is 5mg:100ml;
