Abstract
The effective component of said adjuvant is 8-methyl-6-decene vanilla stem amine which can be extracted from natural plant tianyingjiao by using ethyl alcohol, and can be extensively used in plant source pesticides, organophosphorous pesticides and cinerins pesticides. It features stable biochemical property and long effective time, the addition of said adjuvant can greatly reduce dosage of pesticide, and can make pesticide produce high effect.
Description
The present invention relates to the insecticide technical field.
The chemical synergists of synthetic (auxiliary agent) as: methylenedioxy benzene phenolic group because of compound (being called for short the MDP compound), people observe sesame oil and succeed in developing for pyrethrin synergy, the MDP compound not only has obvious synergistic effect to pyrethrins, and other insecticides are also had synergistic effect more or less.The MDP compound, commercial have a kind surplus Butacide, CPR dust, synergy alum, propyl isome, Piprotal, Bucarpolate, the Asarinin (sesamin) etc. 50, is the important synergist of present agricultural chemicals.But this synthetic auxiliary agent (synergist) is not broken away from chemical substance more or less to human environment and ecological influence and harm.On the other hand, this synergist mostly is oxidase inhibition type compound greatly, its synergistic mechanism dullness, and quick-acting is poor, and synergy control face is less.
The purpose of this invention is to provide a kind of pesticide plant source auxiliary agent preparation method and purposes, auxiliary agent of the present invention not only has the notable synergistic effect, add this auxiliary agent after, pesticide dosage can significantly reduce, and quick-acting to pest efficient, and is safe in utilization, its biochemical property is stable, and the lasting period is long; Reparation technology is easy, and cost is low, and is of many uses, easy to utilize.
The present invention is achieved in that a kind of pesticide plant source auxiliary agent, it is characterized in that its active ingredient is 8-methyl-6 rare vanilla stem in last of the ten Heavenly stems amine.
Empirical formula of the present invention is: C18H27NO3, chemical name is: 8-methyl-6 rare vanilla stem in last of the ten Heavenly stems amine is commonly called as the clusterred pepper alkaloid.
Its structural formula can be following several:
A kind of preparation method of pesticide plant source auxiliary agent, it is to extract from the natural plants clusterred pepper, 8-methyl rare vanilla hydrogen in 6 last of the ten Heavenly stems amine, extraction process adopts the solvent impregnation can dissolve the 8-methyl-6-last of the ten Heavenly stems rare vanilla stem amine.Solution can be used ethanol, acetone, chloroform, ether etc.
The alcohol dipping method is as follows:
A, earlier with the clusterred pepper drying, be ground into sheet,
B, under 75-85 ℃ of condition, extract weight ratio: clusterred pepper again with 95% ethanolic solution is free in the lixiviate cylinder: ethanolic solution=1: 1.5-10, or more.
C, 48 hours enter in the still concentrating under reduced pressure and catch up with water to remove ethanol after the sub-micron suction strainer is handled, and last moisture is≤5 ‰.
The purposes of the described pesticide plant source auxiliary agent of a kind of claim 1 is used for doing in botanical pesticide organophosphorus insecticide or the pyrethrin pesticide builder and uses.
Botanical pesticide such as rotenone emulsifiable solution, matrine, melia toosendan etc.
Organophosphorus insecticide such as phoxim 1605, flolimat or nuvacron etc.
Chrysanthemum ester etc. is killed in pyrethrin pesticide such as decis, cypermethrin, Chinese and Western.
Auxiliary agent of the present invention has following characteristics: (1) synergistic effect is obvious, add this auxiliary agent after, pesticide dosage can significantly reduce; (2) insect there are efficient, quick-acting killing actions; (3) be natural extract, safe in utilization, the nonhazardous of this auxiliary agent to warm blooded animal, comprise the mankind, poultry, birds etc., and crops significantly reduces pesticide dosage and harm; (4) biochemical property is stable, and the storage life term of validity is long; (5) reduce drug cost greatly.Reparation technology of the present invention is easy, and cost is low, and raw material sources are wide.The present invention is of many uses, can be used in the organophosphorus insecticide, also can be used for also can be used in the pyrethrin pesticide in the pyrethrin pesticide, or plant resource agent extremely early, agricultural chemicals is made builder and is used.
Below in conjunction with embodiment the present invention is described in detail, but not as a limitation of the invention.
Reparation technology embodiment 1: earlier the clusterred pepper drying is anhydrated, be ground into sheet, get material 400kg; Join in the lixiviate cylinder, add the ethanolic solution 800kg lixiviate of 95% concentration, treat 48 hours after, solution is emitted; Enter in the reactor after sub-micron rotary vacuum filter suction strainer is handled, heat 75-85 ℃, concentrating under reduced pressure is caught up with water, removes ethanol, determination of moisture, and≤3-5 ‰.And after chromatograph mensuration content was qualified, 95% ethanolic solution about 40-50 was sneaked in discharging again, so that the clusterred pepper alkaloid is generally 50-60%, and Yu Weishui and ethanol thereof.Outward appearance is thick brown liquid, pH value 7.0-7.5, and water quality mark≤0.5%, ethanol protection auxiliary agent long preservation is never degenerated, and does not change auxiliary agent chemical property and smell.
Other several embodiment parameters are as follows:
| Broken clusterred pepper weight | 95% ethanolic solution weight | Extraction time |
| ????400kg ????400kg ????400kg | ????600kg ????1200kg ????4000kg | ????48H ????72H ????50H |
Purposes embodiment is as follows:
Raw material is the thick brown liquid (or using pure active ingredient) of 50-60% with the clusterred pepper alkaloid.
The embodiment consumption proportion can be listed as follows:
| Pesticide variety | The agricultural chemicals addition accounts for original (weight ratio) after utilizing the present invention | The pesticide active ingredient reduction |
| 1605 flolimat nuvacron rotenone emulsifiable solution matrines | ????40-50％ ????40-50％ ????40-50％ ????40-50％ ????40-50％ | ????50-60％ ????50-60％ ????50-60％ ????50-60％ ????50-60％ |
| The chrysanthemum ester is killed in decis cypermethrin Chinese and Western | ????40-50％ ????40-50％ ????40-50％ | ????50-60％ ????50-60％ ????50-60％ |
The pesticide active ingredient consumption significantly reduces, and therefore can effectively reduce toxicity and the poisoning of pesticidal preparations to warm blooded animal and crops.
Other test effects are as follows:
1, quick-acting, efficient: as to add under 1500 times of situations of water at the plant insecticide hypertonic emulsifier rotenone oil as agricultural chemical with the present invention, aphid, two spotted spider mite were knocked down prestissimo 50 seconds-1 minute, be generally 1-2H originally without the present invention.
Insecticidal effect improves more than 3 times at 85-94% than not adding the contrast of this auxiliary agent., be about 80% originally.
2, the synergist consumption reduces: this auxiliary agent is added into 2.5%-6%, and general chemical synergists such as the MDP amount of allocating into are 10-20%, and cost reduces greatly.This auxiliary agent nontoxic (but forbidding pleasing to the eye).
