Abstract
The invention discloses a clothianidin synergetic patch and a preparation method thereof. The patch is composed of the following raw materials in percentage by weight: 0.1 to 10% of clothianidin crude drug, 5 to 40% of solvent, 0.5 to 2% of synergist, 5 to 10% of anti-freezing agent, 1 to 2% of moisture absorbing agent, 0.1 to 1% of antiseptic, and the balance being tackifier; wherein the synergist can be laurocapram, fatty alcohol-polyoxyethylene ether, sodium diethylhexyl sulfosuccinate, R-mannitol or S-mannitol. The preparation method comprises the following steps: making the raw materials mentioned above into paste, painting the paste on elastic cloth covered by a layer of solvent basic rubber, and finally covering the paste by a piece of protective paper. By selecting a proper synergist, the produced clothianidin synergetic patch has the following advantages: the responding time is short, the effect can last for a long time, the recovery is convenient, the human cost is low during the application process, the patch cannot be washed off by rain easily, the drug effect can last for a long time, and the patch is pollution-free to the environment.
Description
Technical field
The present invention relates to pesticide field, be specifically related to a kind of clothianidin synergistic patch and preparation method thereof.
Background technology
Clothianidin is a kind of insecticide in anabasine, is the novel pesticide of a class highly effective and safe, high selectivity, and its effect is similar with nAChR, have tag, stomach toxicity and systemic activity.To be mainly used on paddy rice, vegetables, fruit tree and other crops anti-ly eliminating aphis, leafhopper, thrips, the Semiptera such as plant hopper, coleoptera, diptera and some Lepidoptera class pest insecticide, have efficient, wide spectrum, consumption are few, toxicity is low, the drug effect lasting period long, to crop without poisoning, use safety and conventional pesticide without advantages such as cross resistances, having remarkable interior suction and osmosis, is the another kind of alternative high-toxic organic phosphorus agricultural chemicals.
At present, China and the world are all based on liquid preparation, and solid pharmaceutical preparation increases year by year, are in use water-solublely sprayed at crop leaf surface.Use the waste of middle solvent and former medicine all very serious, to environment, the mankind and livestock form directly harm.Along with the increase of mankind's environmental consciousness, environmental administration requires more strict to the safety of Pesticide use and the feature of environmental protection, invents a kind of resource-conserving, environmentally friendly pesticidal preparations is imperative.
Patch in use convenient, pollution-free, that the rate of recovery is high feature will become the new developing direction of pesticidal preparations.The preparation method of patch has a variety of, but the drug effect of clothianidin patch all can not get a desired effect at present.
Summary of the invention
Based on the above state of the art, the object of this invention is to provide a kind of clothianidin synergistic patch that fast clothianidin can be transported to each position of plant corpus, effectively improve clothianidin drug effect, and provide its preparation method further.
For solving above technical problem, the present invention takes following technical scheme:
A kind of clothianidin synergistic patch, is characterized in that it comprises the raw material of following mass percent: the former medicine of clothianidin: 0.1-10%; Solvent: 5-40%; Synergist: 0.5-2%; Antifreezing agent: 5-10%; Hygroscopic agent: 1-2%; Preservative: 0.1-1%; Tackifier: surplus; Wherein said synergist is selected from azone, fatty alcohol-polyoxyethylene ether, aerosol-OT salt, R-mannitol or S-mannitol.
Preferably, described solvent is DMF, and described antifreezing agent is ethylene glycol; Hygroscopic agent is glycerine; Preservative is sodium citrate; Tackifier are the rosin/oil miscible solvent compound of mass ratio 3:1.
The preparation method of described clothianidin synergistic patch, its step is as follows:
(1) take each raw material in proportion, by former for described clothianidin medicinal described dissolution with solvents, add described synergist and antifreezing agent stirs, then add described hygroscopic agent, preservative and tackifier and continue to stir, obtain paste;
(2) by pressed disc method, solvent-based glue is squeezed on stretch fabric, thickness 0.2mm; Then be squeezed on described solvent-based glue by the paste of step (1) gained, thickness 1-2mm, finally presses protection sheet on described paste.
Preferably, described solvent-based glue is two-layer, is followed successively by acrylic acid and Malaysia glue from inside to outside, and its thickness is respectively 0.1mm.
The beneficial effect adopting technique scheme to produce is: the present invention is by selecting suitable synergist, in use responding time is short for obtained clothianidin synergistic patch, duration is long, it is convenient to reclaim, use procedure cost of labor is lower, not easily by rain drop erosion, effective drug duration is long, environmentally safe.
