Abstract
A piperin insecticide for rice, wheat, fruit tree, vegetables, etc is proportionally prepared from piperin, artemisine, lindestrenol, synergistic, stabilizer, surfactant, antiseptic, organic solvent and pH regulator. Its preparing process is also disclosed.
Description
Technical field
The invention belongs to the botanical biological pesticide field, relate to a kind of pepper element pesticide and preparation method thereof particularly.
Background technology
Utilize biological nature, i.e. some contained composition of plant, the damage by disease and insect of control crops 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.
For promoting the agricultural crops increasing both production and income, in decades, China's agricultural crops uses chemical pesticide 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, makes medicine effective ingredient complexity, and is difficult to detect, and it is stable that drug effect is difficult for, and insecticidal effect is slow.And be not easy to reach research and the application that improves drug effect or enlarge insecticidal spectrum according to its drug mechanism and the mutual compatibility of other agricultural chemicals.
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 pepper element pesticide 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 the pepper element, or pepper element, 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.
Pepper element pesticide of the present invention is made (consumption is a weight portion) by following component:
The plain 13-70 part of pepper, qinghaosu 0-6 part, fragrant camphor tree alcohol 0-17 part, synergist 0.1-3 part, stabilizing agent 3-11 part, surfactant 11-16 part, preservative 0.4-7 part, organic solvent 13-60 part, PH conditioning agent 0.08-0.3 part.Wherein qinghaosu, fragrant camphor tree alcohol can be simultaneously zero or single be zero.
Described pepper element is that fruit of pepper tree and/or blade are pulverized, soaked, and adopts organic solvent extractionprocess or supercritical extraction or ultrasonic extraction method or microwave extraction method, the insecticidal activity composition from extract acquisition pepper, i.e. pepper element.
Described surfactant contains non-ionic surface active agent and anion surfactant: non-ionic surface active agent is selected at least a in alkylphenol formaldehyde condensation product, bis-phenol polyethers, fatty acid glyceride and derivative, fatty acid glycerine fat, alkyl amine oxide, the basic amine alkoxide for use; Anion surfactant is selected toluenesulfonate, C for use
9-C
12At least a in alcohol APEO, alkylphenol-polyethenoxy sulphate, dialkyl group succinic acid fat sulfonate, the alkyl naphthalene sulfonate.
Described organic solvent is selected at least a in methyl alcohol, ethanol, formaldehyde, mixed alcohol, acetone, dibutyl ester, dioctyl ester, liquor, gasoline, the diesel oil for use.
Described synergist is selected any in azone, DHS activator, synergy phosphorus, 920, the three fourth phosphorus for use.
Described stabilizing agent is selected any in epoxidized vegetable oil, monomethyl ether, the single ethyl ether for use.
Described PH conditioning agent is selected any in acetic acid, sulfuric acid, phosphoric acid, the sodium carbonate for use.
Described preservative is stupid sodium formate.
Described insecticide is the said any formulation of botanical pesticide.As: wetting powder, cream preparation, suspension formulation etc.
The preparation method of described pepper element pesticide
One. preparation pepper element
(1). fruit and/or the leaf of pepper are pulverized, with methyl alcohol, ethanol, formaldehyde, at least a immersion of mixed alcohol, again with acetone, dibutyl ester, at least a repeatedly extraction of dioctyl ester;
(2). extract is concentrated at temperature 20-100 ℃, and the time is 3-12 hour, is concentrated into the flowing soaking paste extract;
(3). extract is separated, purifies with thin layer folding method, make the pepper element.
Two. the preparation pepper element pesticide
(1). by weight with the plain 13-70 part of pepper, qinghaosu 0-6 part, fragrant camphor tree alcohol 0-17 part, organic solvent 13-60 part, adding has in the mixing kettle of agitator, is heated to temperature 20-100 ℃, mixes 3-12 hour;
(2). add surfactant 11-16 part, synergist 0.1-3 part, stabilizing agent 3-11 part, preservative 0.4-7 part, PH conditioning agent 0.08-0.3 part mixes, and obtains cream preparation.
This pepper element pesticide can also adopt other existing botanical pesticide preparation method to make any biopesticide formulation.
With the pepper element, or pepper element, qinghaosu and/or fragrant camphor tree alcohol allocates surfactant into, and antioxidant, stabilizing agent, synergist, anti-photolysis agent, cosolvent, PH conditioning agent, carrier are made the wetting powder of pepper element pesticide.
With the pepper element, or pepper element, qinghaosu and/or fragrant camphor tree alcohol allocates surfactant, preservative, stabilizing agent, synergist, organic solvent, PH conditioning agent into, makes the cream preparation of pepper element pesticide.
With the pepper element, or pepper element, qinghaosu and/or fragrant camphor tree alcohol allocates surfactant, antioxidant, synergist, anti-photolysis agent, stabilizing agent, organic solvent into, makes the suspension formulation of pepper element pesticide.
The present invention has following advantage:
1. wide spectrum, insecticidal effect efficiently
This pepper element pesticide has the various pests in wheat, paddy rice, fruit tree, vegetables, flowers, the forest significantly to be killed and control efficiency.
2. hypotoxicity
Raw material of the present invention derive from natural plant, and particularly pepper is that the mankind are generally edible, safe in utilization.
3. friendly environment, the noresidue characteristic
The plain penetration of pepper is strong, and the biological nature volatilization is very fast, is taken at nature, is used for nature, does not have strong toxic residue.
4. not having the three wastes handles
The production process economic security, all lixiviate soups all reclaim, and the plant slag after the extraction can be used for crop as fertilizer.
The present invention reaches research and the application that improves drug effect or enlarge insecticidal spectrum according to its drug mechanism and the mutual compatibility of other agricultural chemicals easily.
