Abstract
The present invention relates to a water dispersed nimbin granule and a preparation method thereof. The present invention has the following two formulas by weight percentage: first, 0.05 to 60 % of nimbin and an auxiliary agent as the rest; second, 0.05 to 50 % of nimbin, 5 to 15 % of wetting agent, 10 to 20 % of binding agent, 10 to 30 % of disintegrating agent and 20 to 60 % of carrier. The present invention has the preparation process that the formula materials are pulverized, granulated, dried, sieved, analyzed, tested and warehoused.
Description
Technical field
The invention belongs to vegetable insecticide and preparation method thereof, be specifically related to water dispersed nimbin granule and preparation method.
Technical background
Now, a large amount of chemical insecticides that use on agricultural, because its toxic and side effect, the protection for the mankind, livestock and natural environment has all brought great harm and many negative effects.Thereby such as using the person poultry poisoning of institute's initiations generation to put aside poisoning for a long time, manslaughtering a large amount of useful natural enemies and be harmful to the ecotope disequilibrium that natural enemy easily develops immunity to drugs and causes ... or the like.Therefore, many developed countries and area have been ordered and have been forbidden promoting the use of chemical insecticide, make great efforts development and apply biopesticide.So, no matter be domestic or external, all in the usage ratio that reduces chemical pesticide by every means as early as possible.
Summary of the invention
The objective of the invention is to disclose and a kind of nimbin is processed into water dispersible granules, avoid with an organic solvent, improve the content and the stability of nimbin in the preparation, improve drug effect, be convenient to the water dispersed nimbin granule and the preparation method that store and transport and use.
Prescription of the present invention is
Prescription one (weight %):
All the other are auxiliary agent for nimbin 0.05%-60%.
Prescription two (weight %):
Nimbin 0.05%-50% wetting agent 5%-15% binding agent 10%-20% disintegrant 10%-30% carrier 20%-60%.
The nimbin of above-mentioned prescription is one or more among seal chinaberry A, B, D, E, F, G, H, I, K, the L.Can be the pure product of nimbin, also can be neem oil, also can be vegetable oil extraction thing or the nimbin preparation that contains nimbin.When use was multiple, total amount can not be greater than the deal of prescription proportion.Nimbin can be pure product, also can be neem oil, also can be vegetable oil extraction thing or the nimbin preparation that contains nimbin.
The auxiliary agent of above-mentioned prescription is made up of wetting agent, binding agent, disintegrant and carrier.
Wetting agent is: saponin, lignosulfite; the hydrolysate of animal waste, alkyl sulfate, alkene sulfonate; benzene sulfonamide acid alkali metal salt and amine salt, dialkyl group succinic acid sulfonate sodium, fatty alcohol, fatty acid amide N methyl taurine sodium salt, aliphatic alcohol polyethenoxy sulphate, alkyl tea sodium sulfonate, fatty acid or fatty acid ester sulphate, sodium lignin sulfonate, petroleum sodium sulfonate, alkyl biphenyl ether sulfonic acid sodium, tea phenol sulfonic formaldehyde condensation compound sodium salt, polyoxyethylene carboxylate sodium sulfonate and amine salt, alkylphenol polyoxyethylene, fatty alcohol-polyoxyethylene ether.
Binding agent is: starch, dextrin, gum Arabic, soybean protein, casein, gelatine and gelatin, sodium silicate, gypsum, poly-cruel vinyl acetate, polyvinyl alcohol, rosin, shellac, paraffin, pitch, ethene-vinyl acetate copolymer resins.
Disintegrant is: sulphur ammonium, calcium chloride, salt, aluminium chloride, urea, bentonite.
Carrier can be: soybean, tobacco, acorn, corncob cellulose, rice husk, sulphur, diatomite, quicklime, magnesium lime, apatite, calcite, dolomite, gypsum, mica, talcum, pyrophyllite, clay, kaolinite, nacrite, dickite, anauxite, montmorillonite, activity go up in vain, float stone etc.
Manufacture craft of the present invention is;
The formulation material mixture is carried out granulation after the ultra-fine grinding, drying, screening, sample analysis, qualified can the packing.
The present invention has following advantage:
1, present seal chinaberry preparation mostly is missible oil greatly, it is a kind of compound from plant seal chinaberry, has good insecticidal activity, very fast degraded in environment, do not injure natural enemy and other non-target organism, its shortcoming is unstable, and the processing formulation is less, consume a large amount of organic solvents, and cause pollution environment.After nimbin is made water dispersible granules, can widen the scope of application of medicament, prolong the lasting period, improve drug effect.Save organic solvent, do not cause pollution environment.
2, after nimbin is made water dispersible granules,, not only alleviated destruction, and reduced production cost ecotope owing to do not contain organic solution.
3, after nimbin is made water dispersible granules, can greatly alleviate toxic action to various natural enemies.
4, after nimbin is made water dispersible granules, be convenient to the packing storing.
Embodiment
In order to understand the present invention better, describe the technology contents of invention below in detail with example.
Embodiment one: produce 3% nimbin water-dispersible granules:
(1) adds 8% (weight) calcium lignosulfonate as wetting agent;
(2) add 9% (weight) ethene-vinyl acetate copolymer resins as stick;
(3) add 60% (weight) atlapulgite as carrier;
(4) add 20% (weight) urea as disintegrant;
(5) add 3% (weight) nimbin;
Mixture is carried out granulation after the ultra-fine grinding, drying, screening, sample analysis, qualified can the packing.
Embodiment two: produce 40% nimbin water-dispersible granules;
(1) adds 8% (weight) sodium lignin sulfonate as wetting agent;
(2) add 19% (weight) polyvinyl acetate as stick;
(3) add 20% (weight) anauxite as carrier;
(4) add 13% (weight) bentonite as disintegrant;
(5) add 40% (weight) nimbin;
Mixture is carried out granulation after the ultra-fine grinding, drying, screening, sample analysis, eligible can be packed.
With 3% nimbin water-dispersible granules of the present invention the field efficacy of diamondback moth larvae is illustrated below the advantage of preparation of the present invention:
With 3% nimbin water-dispersible granules of the present invention, 0.3% nimbin emulsion dilute respectively 20000 times, To diamondback moth larvae spraying processing, the 3rd, 7,14 day investigation insect population decline rate respectively after medication after 1500 times Be 50.25%, 40.45%; The 7th day insect population decline rate is respectively 84.50%, 80.63%; The 14th day The insect population decline rate is respectively 92.91%, 60.21%. 3% nimbin water-dispersible granules of the present invention is described Preventive effect is higher than 0.3% nimbin emulsion, both can reduce dosage, can prolong again the lasting period of medicament.
