Abstract
A disinfectant for preventing and treating wheat bakanae disease, tomato botrytis, apple anthracnose, hot pepper phytophthora, etc. is prepared from the root, stem, leaf and fruit of sophora alopecuroides through crushing, extracting in mixed organic solvent, concentrating, and mixing with proper solvent or assistant to obtain emulsified oil or microemulsion. Its advantages include low residue, high safety and high effect.
Description
The invention belongs to the pesticide processing field, specifically a kind of sophora herb disinfectant and method for making thereof.
Sophora alopecuroide (Sophora alopecuroides L.) is a cassia leguminous plant, the western beans root of other name, foxtail-like sophora root, herba sophorae alopecuroide.Sophora alopecuroide is a perennial herb, high 15～100cm, the densely covered canescence volt of complete stool kiginu shape pubescence.The thick shape of rhizome, diameter can reach 2cm, horizontal walk.Stem is upright, lignification slightly, top branch.Sophora alopecuroide generally the early April～sprout the middle ten days, June～early July blooms, 7～mid-August the result, 8～mid-September fruit maturation.Sophora alopecuroide is a geophyta rhizomatosa, can spend the winter of severe cold.Along with the development of rhizome, just grow thickly in flakes through breeding for many years, its rhizome prosperity, root width of cloth length can reach 2～3m, and vertical root can reach 2m downwards.Owing to be rich in alkaloid in its root, stem, leaf and the fruit, mainly contain matrine, oxymatrine, sophocarpine, sophoramine and eulexine, thereby Sophora alopecuroide have very high medical value.
Sophora alopecuroide mainly is distributed in the northwest wide geographic area of China, suitable is born in more moistening location in area, desertification grassland and the desert district, usually and ground water system network and subterranean water level close getting in touch arranged.So it is big to deposit China's Sophora alopecuroide distribution area, phytomass is big, and the development and use for it on the resource provide guarantee.
Sophora alopecuroide is in pharmaceutically purposes, and Chinese scholar and medical worker have been done big quantity research and prison bed application work.Total alkaloid of sophora alopecuroide and wherein each monosomic alkali all have the effect of heat clearing and inflammation relieving according to research reports, and the treatment cancer is also had certain effect; Sophora alopecuroide also can cure mainly bacillary dysentery and enteritis, psoriasis, eczema, laryngalgia, cough, toothache, stomach trouble, scald etc.
Use on agricultural with the control crop pest about Sophora alopecuroide, just on the books in " Chinese soil pesticide will " book, a lot of afterwards scholars are to its deep research of also contrasting.It is reported that the Sophora alopecuroide water cooking liquid can be prevented and treated cabbage sawfly, two spotted spider mite, cabbage caterpillar and thrips etc.In addition, contain alkaloid in the Sophora alopecuroide certain plants is also had the effect of stimulating growth, it can improve the activity of indoleacetic acid oxidase in the plant.1998, Luo Wanchun applied for " Sophora alopecuroide insecticide " patent.But Sophora alopecuroide did not also have report in the research that prevents and treats aspect the crop pest.
The present invention finds that by the effect research of sophora alopecuroides extract to crop pest Sophora alopecuroide all shows good restraining effect and control efficiency to the various crop disease under stripped and condition of living body, has very high research and development and is worth.The objective of the invention is to, Sophora alopecuroide is developed to the nuisanceless bactericide that can be used for control of crop disease, to serve agricultural production.
Below narrate detailed content of the present invention:
A kind of sophora herb disinfectant, it is characterized in that root, stem, leaf and fruit with Sophora alopecuroide (Sophora alopecuroides L.) are raw material, use methyl alcohol: the mixed solvent of interior ketone=1: 1 extracts, and extract is mixed with sophora herb disinfectant with solvent, insecticides adjuvant again.
The each component percentage by weight of bactericide missible oil of the present invention is:
Sophora alopecuroides extract 10～40%
Solvent 20～50%
Insecticides adjuvant 10～20%
The each component percentage by weight of bactericidal microemulsion of the present invention is:
Sophora alopecuroides extract 10～40%
Solvent 10～20%
Water 30～50%
Insecticides adjuvant 10～20%
Solvent of the present invention can be methyl alcohol, ethanol, isopropyl alcohol, benzene, dimethylbenzene, any in the kind of ethyl acetate etc. or several, and the known material of those skilled in the art;
Insecticides adjuvant of the present invention can be the formaldehyde condensation products of sodium lignin sulfonate or calcium, alkyl naphthalene sulfonate, nekal, polycarboxylate sodium salt, any in neopelex, dioctyl sodium sulfosuccinate, the alkyl polyoxyethylene ether sulfonate or several mixture.And the known material of this area staff;
Water in the Sophora alopecuroide bactericidal microemulsion refers to deionized water or distilled water.
Below narrate manufacture method of the present invention:
Gather root, stem, leaf and the fruit of Sophora alopecuroide, dry under natural air drying or 50 ℃～60 ℃ conditions, crushed after being dried is to crossing 40 mesh sieves; With 3 times of methyl alcohol to the Sophora alopecuroide crushed material: the mixed solvent of acetone=1: 1 extracts, require during extraction to reflux, 70～80 ℃ of temperature, 6 hours extraction times, extract is concentrated under vacuum condition, the Sophora alopecuroide crushed materials that are concentrated into and add etc. are heavy, promptly get Sophora alopecuroide root, stem, leaf and fruit extract.
This extract and solvent, insecticides adjuvant can be able to be mixed with Sophora alopecuroide sterilization missible oil by prescription provided by the invention, its method for making is: in reactor, add each composition successively by sterilization missible oil proportional quantity, stir get final product Sophora alopecuroide sterilization missible oil.
This extract and solvent, insecticides adjuvant and water can be mixed with the Sophora alopecuroide bactericidal microemulsion by prescription provided by the invention.Its method for making is: earlier with sophora alopecuroides extract, insecticides adjuvant is dissolved in the solvent, at 40～50 ℃, under the high-speed stirred situation gained solvent is added dropwise in the distilled water, and constant temperature stirred 1 hour, promptly got the Sophora alopecuroide bactericidal microemulsion.
The present invention compares than prior art has following typical advantages:
1, non-environmental-pollution.
2, fungicidal spectrum is wide.Evidence, medicament provided by the invention can effectively be prevented and treated various crop diseases such as wheat scab, graw mold of tomato, apple anthracnose, the corn northern leaf blight, Phytophthora capsici disease, gray mold of cucumber.
3, have residual low, to the advantage of people, animal safety, be a kind of nuisance-free plant source bactericide.
The present invention can provide by following embodiment:
Embodiment 1: takes by weighing Sophora alopecuroide root, stem, leaf and fruit crushed material 100Kg, uses acetone 150kg, and methyl alcohol 150kg, refluxing extraction is 6 hours in multi-functional extraction still, and temperature is 70 ℃ during extraction, gets extract 250kg; To 100kg, promptly get Sophora alopecuroide root, stem, leaf and fruit extract with vacuum concentration method concentrated extracting solution.
