Description
Technical field
The invention belongs to technical field of insecticide, and in particular to a kind of method that use eupatorine prepares insecticide.
Background technology
Eupatorium adenophorum (scientific name:Eupatorium adenophoraSpreng.)：Perennial herb is planted into suffruticose
Thing, the sturdy prosperity of rhizome, uprightly, 30-200 centimetres of plant height, branch opposite, tiltedly on, stem purple, by white or rust pubescence,
Leaf opposite, blade matter is thin, and avette, triangle or water chestnut shape are avette, and outside of belly green, back side color is shallow, and edge has sparse thick without advising
Sawtooth then, is then wavy shallow sawtooth or nearly full edge below inflorescence, capitulum is small, and diameter is up to 6 millimeters, in the arrangement of branch end
Into umbrella room or compound corymb, containing about 40-50 little Hua, tubular flower both sexes, white.Sub- reality achene, dark brown.Every plant can produce per year
Achene 10,000 or so, propagates, is distributed mainly on the ground such as China, the U.S., Australia, New Zealand with the wind by pappus, is a kind of weight
The quarantine harmful organisms wanted, be China by foreign term exemplary, but eupatorium adenophorum extracting solution to natural enemy without
Evil, can be used as insecticide, bactericide and plant growth regulator.
The important measures that insecticide is modern agriculture are prepared using Invasive Alien Species, had both been realized to exotic invasive
The control of species, and provided to plant insecticide and new produce approach.
Prior art such as, Chinese invention granted patent document, the B of Authorization Notice No. CN 102696693, the disclosure of the invention
A kind of compound type botanical pesticide and preparation method thereof and application, it by following weight than dispensing be prepared from：Purple stem pool
Orchid 5 ~ 35, fragrant eupatorium herb 1 ~ 20, lantana 1 ~ 20, solvent 20 ~ 35, cosolvent 1 ~ 5, synergy levelling agent 1 ~ 5, stabilizer 0.5 ~ 10,
Surfactant 0.5 ~ 5, water 20 ~ 70；Eupatorium adenophorum, fragrant eupatorium herb, lantana are cleaned and crushed, is respectively put into solvent and soaks
5 ~ 7 days, the extraction of essential oil liquid of Eupatorium adenophorum, fragrant eupatorium herb, lantana is obtained, extraction of essential oil liquid is uniformly mixed and heated, added
Surfactant, stabilizer, water, uniform mixing.The beneficial effect of the invention is：Using Invasive Alien Species as the master prepared
Raw material, realizes effective control to Invasive Alien Species, turns bane into boon, both realized the function of desinsection, effectively alleviated one
As insecticide pest resistance to insecticide problem, environmental pollution is not resulted in again, at the same also have preparation technology it is simple, practical and convenient
Feature, but only by immersion, the active ingredient for the Eupatorium adenophorum being obtained by extraction may be slightly poor, and formula and preparation method also have
There is optimization space.
Prior art such as, Chinese invention granted patent document, Authorization Notice No. CN1218643C eupatorines insecticide and its
Preparation method, be characterized in cleaning Eupatorium adenophorum, crush, organic solvent and/or water mixing immersion, extract, filtering, extraction,
Chromatograph, be concentrated into Herba Lycopi's alkali extract of flowing soaking paste, Extracting temperature is 40-85 DEG C, the time is 2-9 hours, obtains product.Will
