The present invention discloses a piperine insecticide and its preparation method. Its composition contains (by weight portion) 0-70 portions of piperine, 0-6 portions of artemisinin, 0-17 portions of lindestrenol, 0.1-3 portions of synergistic agent, 3-11 portions of stabilizing agent, 11-16 portions of surfactant, 0.4-7 portions of preservative, 13-60 portions of organic solvent and 0.08-0.3 portion of pH regulating agent. Said piperine insecticide can obtain obvious effect for killing various injurious insects. Besides, said invention also provides the concrete steps of its preparation method.
Description
Technical field
The invention belongs to the botanical biological pesticide field, relate to a kind of piperine insecticide and preparation method thereof particularly.
Background technology
Utilize biological characteristic, i.e. some contained composition of plant, the damage by disease and insect that the control crops are had to has it from ancient times.For the understanding and the application of some composition of plant characteristic,, in the books such as Compendium of Material Medica of China's first pharmacy monograph Shennong's Herbal and Ming Dynasty's Li Shizhen (1518-1593 A.D.), very full and accurate elaboration was arranged all as far back as Eastern Han Dynasty last years of a dynasty or reign.In numerous in ancient times pharmacy monographs, just once mention sweet wormwood, golden cypress, kaladana, rhizome of cyrtomium etc. all has insecticidal properties to our ancestors.
Be to promote the agricultural crops increasing both production and income, in decades, China's agricultural crops chemical pesticide of having to use in a large number.A large amount of uses of chemical pesticide have caused heavy damage to human ecological environment.Develop and applying biological pesticide control diseases and pests of agronomic crop, become a kind of inexorable trend of historical development.
And general botanical pesticide, because of preparation method's simple coarse, make medicine effective ingredient complexity, and be difficult to detect, drug effect is difficult for stable, the insecticide effect is slow, and is not easy according to its drug mechanism and the mutual compatibility of other agricultural chemicals, reaches the research and the application that improve drug effect or enlarge insecticidal spectrum.
Summary of the invention
The present invention is directed to chemical pesticide to having a strong impact on that human ecological environment causes, general plant pesticide drug effect instability, a kind of piperine insecticide that the drug effect effect slowly provides and preparation method thereof.Be characterized in separating from pepper, extract and to have the effective ingredient of insecticidal effect, with pipering, or pipering, qinghaosu and/or fragrant camphor tree alcohol be Main Ingredients and Appearance, and warp preferably insecticides adjuvant carries out organic assembling and is processed into.
Piperine insecticide of the present invention is made (consumption is a weight portion) by following component:
