Abstract
The present invention relates to an extraction process for extracting Sophora alopecuroide extract and a technological process for preparing sophora alopecuroide cream preparation by using sophora alopecuroide extract and several agricultural chemicals according to the mixing ratio of 1-3:1. Said invention utilizes different mechanism of action and mode of action of the above-mentioned two ingredients for harmful plants, so that said invented sophora alopecuroide cream preparation possesses obvious synergistic effect. Its effective content can be up to 8-30%. It is an effective medicinal preparation which is safe to human body and animals, nuisanceless or less nuisance, and can be used for controlling harmful plants.
Description
The present invention relates to the extractive technique of Herba Sophorae alopecuroidis extract and the Herba Sophorae alopecuroidis extract that produces with this technology and the compounded technology of chemical pesticide.
Herba Sophorae alopecuroidis is a kind of leguminous plants, and its plant itself and secondary metabolites thereof have certain expelling parasite biocidal efficacies.Noresidue hidden danger in environment.
Pyrethroid insecticides (comprising fenvalerate, Deltamethrin, Cypermethrin, cyfloxylate, lambda-cyhalothrin and Fenvalerate etc.) the efficient and sterilant lower that be a class to various pests to higher animal toxicity, but, limited this type of Utilization of pesticides to a great extent because various pests has produced height resistance and agricultural cost height to it.
Volaton (O, O-diethyl-O-(right-phenyl cyano group formaldehyde) monothio phosphoric acid ester) be a kind of organophosphate insecticides of quick-acting low toxicities, various pests there is the better prevention effect, but owing to insect has produced resistance and to mite class weak effect, limited its use aborning it.
Malathion (O, O-dimethyl-S-(1, the 2-ethoxycarbonyl) phosphorodithioate) is a kind of low toxicity organophosphorus compounds insecticidal/acaricidal agent of tool systemic action, but, greatly limited its use on producing because insect (mite) has produced the high resistance property of medicine to it.
Profenofos (O-(4-bromine 2-chloro-phenyl-)-S-n-propyl thiophosphatephosphorothioate) is the asymmetric organophosphate insecticides of a kind of novel tertiary, various pests there is the better prevention effect, but, on producing, limited its use because it is poor to insect quick-acting, evil mite effect is paid no attention to thought of the high shortcoming of agricultural cost.
Pyridaben (2-tertiary butyl-5-(4-tertiary butyl benzylthio-) 4-chlorine pyridazine-3 (2H)-ketone) is a kind of efficient miticide, because its cost height also is restricted in application.
The present invention finds:
One, with an organic solvent from Herba Sophorae alopecuroidis (comprising stem, leaf, flower, fruit and seed), extracts the technology of Herba Sophorae alopecuroidis extract as methyl alcohol, ethanol and trichloromethane etc.
Related extractive technique is:
" reflux extraction " technology: Herba Sophorae alopecuroidis complete stool or seed after learn from else's experience dry and the pulverizing, the extractor (relating to single-action extraction and multiple extraction) of packing into, add raw material 1-10 organic solvent doubly, soak the back refluxing extraction, collect filtrate, after treating that sampling analysis determines that extracts active ingredients finishes, merging filtrate and sampling analysis are by ALOPERINE (aloperine) or Tocosamine (cytisine) content constant volume.Then with waste residue heating recovery solvent.Capable of using as feed or the fertilizer of waste residue.
" cold-maceration " extraction process: get the Herba Sophorae alopecuroidis complete stool or the seed of dry and pulverizing, add raw material weight 1-10 above-mentioned solvent doubly, after fully stirring, soaked 1-72 hour, carry out press filtration or centrifugal, collect filtrate.And then repeatedly in raw material, add an amount of solvent, soak a few hours and after stirring, carry out press filtration or centrifugal.Repeatedly filtrate merges, and collects supernatant liquor by ALOPERINE or Tocosamine content constant volume through post precipitation.Then with waste residue heating recovery solvent, the capable of using as feed or fertilizer of waste residue.
Solvent involved in the present invention has: methyl alcohol, ethanol and trichloromethane etc.
Two, the synergistic complex technology of Herba Sophorae alopecuroidis extract and chemical pesticide.
The raw material that the present invention relates to has Herba Sophorae alopecuroidis extract and Insecticidal and acaricidal agent such as fenvalerate, Volaton, Malathion and pyridaben etc.
This based composition can be processed into the missible oil that active constituent content is 8-30% in proportion according to traditional method.
It is as follows that the technical process of missible oil is processed in the present invention, but be not limited thereto.
Raw material 1 (Herba Sophorae alopecuroidis extract)---------metering
Raw material 2 (or 3,4 ... Deng.Chemical pesticide)---metering
Solvent 1---------------metering-modulation-sampling-discharging-packing-finished product
Solvent 2---------------metering
Emulsifying agent 1 (or 2,3 ... Deng)------metering
Stablizer---------------metering
Emulsifying agent involved in the present invention has QR-01, QR-03, QR-11, QNR-10, farming breast 0201 and 2201 etc.
The present invention is processed into missible oil and can further be illustrated by following " example ".Below all umbers all refer to the effective constituent weight ratio.
10 parts of example 1 Herba Sophorae alopecuroidis extracts
20 parts of Volatons
1 40 parts of solvents
2 20 parts of solvents
8 parts of emulsifying agents
2 parts of stablizers
It is processed into missible oil by above-mentioned flow process.
10 parts of example 2 Herba Sophorae alopecuroidis extracts
6 parts of pyridabens
1 40 parts of solvents
2 34 parts of solvents
8 parts of emulsifying agents
2 parts of stablizers
It is processed into missible oil by above-mentioned flow process.
Use the related pesticide composition of above-mentioned example 1, the method of preventing and treating resistance vegetable aphid, apple yellow aphid and cotten aphid is: when the big generation of above-mentioned insect, this pesticide composition being diluted with water to 1500-2000 times of liquid crop is carried out even spraying, is 93.66-99.81% to second day prevention effect of above-mentioned insect; Above-mentioned pesticide composition being diluted with water to 1500. times of liquid vegetables are carried out even spraying, is 96.58-98.36% to cabbage caterpillar and second day prevention effect of small cabbage moth.
Using the related pesticide composition of above-mentioned example 2, adopt the concentration of 3000 times of water dilutions, is 93.87% to the 10th day prevention effect of European red mite.
Example 1 and 2 related pesticide compositions have showed significant synergism because of its different mechanism of action and mode of action to insect, and said composition is low toxicity and can reduces the generation of agricultural cost and pest resistance to insecticide greatly.
