Abstract
The present invention relates to a technique for preparing a chamaejasmine aqueous emulsion which is a biotic pesticide and is prepared from the root and the stem of plant Chinese stellera root as raw materials by using one of ethanol, methanol, propanol, propanediol, normal butyl alcohol, acetone and isopropylketone or a mixture of the ethanol, the methanol, the propanol, the propanediol, the normal butyl alcohol, the acetone and the isopropylketone as a solvent through the processes of extraction, filtration, pressure reducing concentration and grinding, wherein the content of new chamaejasmine A as the effective component of Chinese stellera root in finished products is from 1.1 to 5%. The products prepared by the present invention have the advantages of high efficiency, low toxicity, no residue, easily obtained raw materials, low cost and simple processes.
Description
Affiliated technical field: the invention belongs to the agricultural chemicals preparation field, specifically is a kind of preparation technology of biological pesticide chamaejasmine aqueous emulsion.
Background technology: produce " pesticide hazards " owing to chemical pesticide has caused serious environmental to pollute, and destroyed the natural equilibrium of the ecosystem, therefore, biopesticide has become the choice drug of prevention and elimination of disease and pests.In China, more existing plant pesticides are formally registered as nicotine, nimbin, fennel artemisin, Tea Saponin, kuh-seng etc., and wherein a part enters the industrialization trial production stage.But present biopesticide insecticidal effect is also not really desirable, and insecticidal spectrum is relative narrower also.
Summary of the invention:
The objective of the invention is to overcome the defective of prior art, for the public provides a kind of preparation technology of biological pesticide chamaejasmine aqueous emulsion, product is efficient, low toxicity, noresidue, raw materials used being easy to get, and with low cost, technology is simple.
The objective of the invention is to realize by following proposal.
Technical scheme of the present invention is: with Chinese Stellera Root (Stellera Chamajasme L.) plant roots, stem is raw material, with a kind of in ethanol, methyl alcohol, propyl alcohol, propane diols, n-butanol, acetone, the isopropyl acetone or their mixture is solvent, produce biological pesticide chamaejasmine aqueous emulsion through extraction, filtration, concentrating under reduced pressure, grinding technics, wherein, the content of the active ingredient new stellerin A of Chinese Stellera Root (Neochamaejovsmin A) is 1.1～5% in the finished product.
In the such scheme, Chinese Stellera Root plant roots, stem are pulverized, used the solvent of 6～20 times of weight of material quantity to extract 2～8 hours down, filter at 60～85 ℃, filtrate is evaporated to 50%～85% under 600～700mmHg, through grind biological pesticide chamaejasmine aqueous emulsion.
In the such scheme, also nonionic can be added in the concentrate or/and a kind of or its compound, amphoteric surfactant, quaternary surfactant, the amino acid surfactant in the anionic surfactant, its addition is 1～15% of a concentrate gross weight, wherein the ratio of compound is an anion surfactant: the weight ratio of non-ionic surface active agent is 1: 0.15～7.5, stirred then 1～2 hour, grind biological pesticide chamaejasmine aqueous emulsion.
In the such scheme, surfactant is the HLB value at 9～16 non-ionic surface active agent or/and anion surfactant; Non-ionic surface active agent is C12～C18 saturated alkoxides APEO, C12～C18 alkylphenol polyoxyethylene, anhydrous sorbitol APEO, fatty acid polyethylene glycol ester, fatty acid alkyl alcohol amide; Anion surfactant is alkylbenzenesulfonate, alkylsulfonate, sulfosuccinic acid C6～C12 alkyl fat, C12～C18 saturated alkyl aliphatic alcohol sulfate, petroleum sulfonate.
The present invention has following characteristics:
1, products obtained therefrom have efficiently, broad spectrum activity, can effectively prevent eliminating aphis, snout moth's larva, mqb, locust, mythimna separata, cabbage caterpillar, cotton bollworm etc., the deinsectization effect is more than 98%.
2, products obtained therefrom is applied widely, is applicable to paddy rice, wheat, corn, soybean, cotton, fruit tree, tealeaves, vegetables, tobacco, flowers etc.
3, raw materials used is natural plants, and biological degradation is fast, non agricultural chemical residuum, and to the person poultry harmless, good to environment compatibility, production process is pollution-free, and technology is simple, and is with low cost.
As seen from last, technology of the present invention has overcome the defective of prior art, and a kind of efficient, wide spectrum, noresidue, raw material are easy to get, with low cost, the simple biological pesticide chamaejasmine aqueous emulsion preparation technology of technology for the public provides.
