Abstract
The synergistic agent of pesticide is prepared with Verbenaceae and Vitex negundo as plant material and through distillation or organic solvent soaking and filtering to extract Vitex negundo essence. When used, Vitex negundo essence is added into chemical or biological pesticide with the added amount being 0.1-95 %. It has obvious synergistic effect, and in the equal pesticidal effect, the pesticide consumption may be reduced by 50-70 % resulting in greatly reduced pesticidal cost.
Description
Technical field:
The present invention relates to agricultural insecticide, particularly relate to a kind of synergist that can improve the known insecticides drug effect.
Background technology:
In recent years, especially after the China joined WTO, in order to adapt to the nuisanceless export requirement of agricultural product, particularly the plant insecticide research and development are very active for biological source insecticide, obtained some gratifying progress.China to tobacco, trifoliate jewelvine, thick fruit reticulate millettia, goat's horn turn round, Azalea pontica (Rhododendron molle), crotons, thunder godvine, Boluo return, the tuber of stemona, seal chinaberry, melia toosendan, if pesticide plants such as skin rattan, sandy ground cypress, Artemisia scoparia further investigate.And develop 10 various plants insecticide kinds such as rotenone, fennel artemisin, Celastrus angulatus, nimbin, toosendanin, Tea Saponin, S-Ethyl ethylthio sulfonate, nicotine, matrine, jervine, anabasine, stemonine.Compare with the chemical insecticide kind, no matter plant insecticide is kind quantity, or the market share all is very little.Therefore, in the foreseeable time, chemical insecticide still will be brought into play important role in crop pests control.Because the pesticide resistance of insect strengthens the consumption of chemical pesticide year by year, and the residual of chemical pesticide makes it environment is caused serious pollution.Therefore, the consumption that how as far as possible to reduce chemical insecticide is human problems of always exploring.
In order to reduce the environmental pollution of chemical insecticide, huge fund: A, new high activity, low toxicity, the low-residual insecticide of exploitation are all dropped in countries in the world; B, exploitation biological source insecticide; C, exploitation insecticidal synergist.With regard to insecticidal synergist exploitation, make progress limitedly these years, and the synergist of being developed itself is with high costs, can't the large-scale application popularization.
Summary of the invention:
The object of the present invention is to provide a kind of raw material sources wide, preparation is easy, and effective, cost is low, nearly all insecticide is all had the plant resource broad spectrum pesticide synergist of synergistic effect.
In order to realize purpose of the present invention, the inventor screens from known plant in a large number, the just careless section of horse (Verbenaceae) the plant five-leaved chaste tree (Vitex negundo L.) that finishing screen is selected a kind of subtropical zone widespread distribution is raw material, it is pulverized the back soak suction method extraction five-leaved chaste tree element with the way of distillation or organic solvent, this five-leaved chaste tree element is insecticidal synergist.
Five-leaved chaste tree element of the present invention is meant from leaf of five-leaved chaste tree plant and seed the volatile fraction that obtains with the way of distillation or with the general name of organic solvent extract from five-leaved chaste tree.According to five-leaved chaste tree be the analysis showed that, the main component in the five-leaved chaste tree volatile oil is olefines such as β-cloves alkene, sabinene, a-thujene, a-and nopinene, a-phellandrene, laurene, citrene and some alcohol, ester class.
When the present invention adopts way of distillation extraction five-leaved chaste tree plain, be after the five-leaved chaste tree plant of field acquisition is pulverized, to put into and steam lattice, by the five-leaved chaste tree plant, distillate part at first through the condenser collection and be the five-leaved chaste tree element with water vapour; When adopting solvent method to extract the five-leaved chaste tree element, be after the five-leaved chaste tree plant of field acquisition is pulverized, add 1～10 times organic solvent, soak and often stirring as benzinum, toluene, dimethylbenzene etc., after 14～28 days, suction filtration, filtrate draining is five-leaved chaste tree element of the present invention.
The plain using method of five-leaved chaste tree of the present invention: the ratio in 0.1%～95% joins the five-leaved chaste tree element in the chemical insecticide.Five-leaved chaste tree element of the present invention joins synergy the best in the chemical insecticide in 20%～80% ratio.When the present invention is aqua or aqueous emulsion or colloidal suspending agent as if insecticide, the five-leaved chaste tree element that should select for use the way of distillation to obtain; If insecticide is missible oil or finish class, the five-leaved chaste tree element that then should select for use organic solvent method to obtain.
When the five-leaved chaste tree element adds in certain insecticide, under equal preventive effect, can reduce this insecticide consumption 50%～70%, and the cost of five-leaved chaste tree element is 10%～20% of a common insecticide cost.Both can reduce the consumption of chemical pesticide, and can reduce cost again.
Embodiment:
Embodiment 1:
With totally 10 kilograms in the five-leaved chaste tree leaves of plants of field acquisition and seed, after the pulverizing, to put into and steam lattice, the flame enrichment boiling enters condenser after making water vapour by the five-leaved chaste tree plant, and the part that distillates at first of collecting through condenser condenses is the five-leaved chaste tree element.Obtain plain 0.5 kilogram of five-leaved chaste tree altogether.
Embodiment 2:
Take by weighing from totally 10 kilograms in the five-leaved chaste tree leaves of plants of field acquisition and seed, after crushed, add 10 kilograms of benzinums, soaked 10 days, between soak period, often stir, soak the back suction filtration, obtain filtrate and be the five-leaved chaste tree element for 5 kilograms.
Below be the plain and insecticidal effect contrast table of various insecticides when 1: 1 proportioning test of five-leaved chaste tree.
Five-leaved chaste tree element and insecticide are used the effect to insect with
