Abstract
The present invention provides a method for preparing auxiliary agents for pesticide plant sources and application thereof. The auxiliary agent whose effective ingredient is 8-methyl-6 decyl sparse vanilla stem amine can be prepared from hawk upturned peppers which are a kind of natural plant by ethanol by way of lixiviation, and can be widely used for plant source type pesticide, organic phosphorus type pesticide, pyrethroid type pesticide, etc. The auxiliary agent has the characteristics of stable biochemical property and long effective period. After the auxiliary agent is added, the dosage of the pesticide can be greatly reduced, pests are killed effectively and rapidly, the harm to warm-blooded animals and crops can be effectively reduced, and the purpose of safe use is achieved. In addition, the auxiliary agent has the advantages of simple preparation process, low manufacturing cost and quality guarantee, and can be widely popularized.
Description
Technical field
The present invention relates to the insecticide technical field.
Background technology
The chemical synergists of synthetic (auxiliary agent) is as: methylenedioxy benzene phenolic compounds (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.Capsaicine only used as mankind's traditional Chinese medicine of curing the disease in the past, never was useful on the report of agricultural chemicals.
Summary of the invention
The purpose of this invention is to provide the purposes of a kind of capsaicine as the pesticide plant source auxiliary agent, auxiliary agent of the present invention not only has the notable synergistic effect, after adding this auxiliary agent, pesticide dosage can significantly reduce, and quick-acting to pest efficient, safe in utilization, its biochemical property is stable, and the term of validity is long, and cost is low, purposes is wide, and is easy to utilize.
The present invention is achieved in that the purposes of a kind of capsaicine as the pesticide plant source auxiliary agent, it is characterized in that capsaicine as the pesticide plant source builder.
Empirical formula of the present invention is: C18H27NO3, chemical name is: 8-first stem-6 last of the ten Heavenly stems rare vanilla stem amine, be commonly called as the clusterred pepper alkaloid, or capsaicine.
Its structural formula can be following several:
A kind of preparation method of this pesticide plant source auxiliary agent, it is to extract from the natural plants clusterred pepper, 8-methyl rare vanilla stem 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 ‰.
Above-mentioned applicable agricultural chemicals can be botanical pesticide, organophosphorus insecticide or pyrethrin pesticide.
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 unhelpful evil 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 makes builder in the plant insecticide agricultural chemicals and use.
Embodiment
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 600kg 48H
400kg 1200kg 72H
400kg 4000kg 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: the agricultural chemicals addition accounted for original pesticide active ingredient reduction after pesticide variety utilized the present invention
(weight ratio) 1605 40-50% 50-60% flolimat 40-50% 50-60% Azodrin 40-50% 50-60% rotenone emulsifiable solution 40-50% 50-60% matrine 40-50% 50-60% decis 40-50% 50-60% cypermethrin 40-50% 50-60% fenvalerate 40-50% 50-60%
The effective finished product consumption of agricultural chemicals 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 kill the hypertonic emulsifier rotenone oil as agricultural chemical of agent early with the present invention at plant resource and add under 1500 times of situations of water, 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).
