Description
Technical field
The present invention relates to a kind of insecticide, and in particular to a kind of plants and flowers plant source efficient pesticides and its preparation side
Method.
Background technology
With the change of global climate, the phenomenon that various crops and forest meet with parasitosis disaster is increasingly severe.At present
The insecticide variety of in the market is various, but in general insecticide can only prevent and treat particular kind of insect, a kind of insecticide control
A kind of insect, but can also insect is developed immunity to drugs insecticide with same kind of insecticide for a long time.
Nursery stock is the sapling for having root system and seedling stem.According to the growth characteristic of nursery stock different times, by the growth of nursery stock
Journey is greatly classified into four periods, i.e. seeding stage, early growth period, Fast-growing stage and Later growth.Because nursery stock is the childhood of plant
Phase, therefore have the characteristics that the speed of growth is fast, is easily caused death by pest and disease damage infringement.
At present, in seedling growth, for prevent pest and disease damage it is usually used be chemical pesticide, used due to a large amount of
Chemical pesticide and caused by problem of environmental pollution be on the rise.Meanwhile chemical pesticide because its without selectivity, to beneficial life
Thing will also result in threat.Moreover, many chemical pesticides are non-degradables or are difficult to degrade, easily in animals and plants cylinder accumulation and
Pollute the enrichment of thing.
As the public is to the requirement more and more higher of " pollution-free food ", " pollution-free food ", market to it is pollution-free, can drop naturally
The ecological agricultural chemical demand of solution also gradually increases.From the point of view of the development of pesticide science, upper " back to nature " is used in pesticide manufacturing
And " Harmless " of agricultural chemicals, it is society and the inexorable trend of Development of Natural Science, therefore new bio broad spectrum pesticide has
Wide development prospect.

Peach 4-7 parts, beggar-ticks 2-6 parts, perilla leaf 3-7 parts, eucalyptus oil 3-7 parts, synergist 6-9 parts, emulsifying agent 7-10 parts, remaining is anhydrous
Ethanol.
Further, a kind of plants and flowers plant source efficient pesticides, are prepared by the raw material of following parts by weight：
19 parts of wilfordine, 11 parts of pokeberry root, freeze green 8 parts, be 9 parts of baeckea frutescen, 4 parts of fructus viticis, 4 parts of Eupatorium adenophorum, 4 parts of Eclipta prostrata, bitter
Join 17 parts of alkali, 9 parts of tallow-seed oil, 8 parts of root of Chinese clematis herb, 3 parts of azalea, 5 parts of oleander, 5 parts of beggar-ticks, 6 parts of perilla leaf, eucalyptus
5 parts of oil, 9 parts of synergist, 8 parts of emulsifying agent, remaining is absolute ethyl alcohol.
Further, the preparation method of a kind of plants and flowers plant source efficient pesticides, it is characterised in that by following step
Suddenly it is made：
S1：Pokeberry root 9-13 parts, the green 7-10 parts of jelly, oleander 4-7 parts, root of Chinese clematis herb 7-11 parts are passed through into airslide disintegrating mill powder
After broken, the 3-5 times of absolute ethyl alcohol weighed is added, it is 7-9 to adjust pH value with sodium bicarbonate, is extracted for 0 .5 hours, filtering, decompression, concentration
After obtain extract solution A；
S2:By wilfordine 17-24 parts, baeckea frutescen 8-10 parts, fructus viticis 4-5 parts, Eupatorium adenophorum 4-6 parts, Eclipta prostrata 3-5 parts, kuh-seng
Alkali 16-20 parts, tallow-seed oil 8-11 parts, beggar-ticks 2-6 parts, perilla leaf 3-7 parts, the impurity elimination of eucalyptus oil 3-7 part selection of crude drugs, meter
Amount, mixing, load diafiltration kettle after crushing, add the organic solvent of 3-7 times of bulk drug weight, be heated to 66-88 DEG C, heating 2-5 is small
When after be percolated to obtain percolate B；

Seed oil, root of Chinese clematis herb, azalea, oleander, beggar-ticks, perilla leaf, effective proportioning of eucalyptus oil raw material, insecticide is made, it is former
Expect that acquisition cost is low, making is simple and convenient, has good insecticidal effect to absolute ethyl alcohol rice, vegetables, fruit tree, tea tree etc., and
It is environmentally safe, meet the requirement of green production；Seedling can be protected well, can effectively be killed off the insect pests, and
And small toxicity itself, nursery stock and human body will not be impacted.
The present invention uses plant material, pure natural, nuisanceless, makees extractant using water or alcohol, simplifies production technology, reduces
Production cost, the agricultural insecticide that the plant component that this technology is extracted makes is free of or contains organic solvent less, residual after processing
Slag can do the carrier of this product, can also do organic fertilizer raw material, the discharge of three wastes material, clean manufacturing, green；User
Just, application method is directly pouring, and can be to be used simultaneously with fertilizer before transplanting, time saving province convenient and swift compared with fumigating insecticide
Power, reduce human cost.
The pokeberry root used in the present invention contains abundant saponin, there is strong inhibitory action for nervous centralis, freezes green
Dyestuff is usually used as, freezes the green effect for playing desinsection in the present invention by extraction, especially for killing acarid class and moth class
Deng insect significant effect, killed off the insect pests within 0 .5-1 hours, oleander contains the glucosides such as oleandrin, digitalin, kills
Locust, aphid significant effect, the other materials that azalea can be benumbed in the insect nerve cooperation present invention kill insect；The present invention kills
Worm agent is made up of plant, and storeroom cooperates, the efficient deinsectization of energy, to person poultry harmless, safe green environmental protection.
