Abstract
The present invention relates to plant insecticide which is mixed and prepared by taking nimbin and lightyellow sophora root alkaloid as principal raw material, and a preparing method thereof. The plant insecticide not only overcomes the disadvantage of slow effect of neem insecticide but also maintains the advantage of long action time of the neem insecticide; the plant insecticide also has the advantages of high efficiency, low toxicity, easy degradation and no residue, drug resistance is not easily generated for pests, environment is not polluted, and the plant insecticide is not only the insecticide but also the novel pesticide preparation of sterilizing agents and antiviral agents.
Description
The present invention relates to a kind of plant insecticide and preparation method thereof.
It mainly is the quality that improves the quantity of crop products, improves crop products that common people use the purpose of agricultural chemicals.More and more higher to the requirement of living environment, quality of life along with the mankind and use chemical pesticide to cause in a large number environmental pollution, the reality of food pollution forces us to have to develop and uses efficient, low toxicity, the easy agrichemical without enviromental pollution for plant of degraded, noresidue.
The seal chinaberry (Azadirachtin) of extracting from Meliaceae plant seal chinaberry (Azadirchta) fruit seed nuclei is a kind of broad-spectrum plant insecticide, it is by growing to the stomach poison function of harmful insect, food refusal effect and to insect growth, and reproductive capability suppresses, destroys the purpose that reaches pest control.Harmless to people and animals and pest natural enemy, and easily degraded, noresidue, free from environmental pollution.
Kuh-seng (Flavescens) is a kind of conventional Chinese medicine, have very strong sterilization, antiviral, improve effects such as body immunity and expelling parasite.Its Main Ingredients and Appearance is matrine, oxymatrine, ammothamnine, Sophocarpine, N-Methylcytisine etc., is referred to as to call alkaloid of sophora flavescens ait.Except that kuh-seng, part plant in the pulse family (as white tattooing, Sophora alopecuroide etc.) is rich in alkaloid of sophora flavescens ait.And these plants distributions are wide, and reserves are big, easily gather.In recent years, alkaloid of sophora flavescens ait except that being extensive use of in the medical treatment, is also widely applied in agricultural fungicides and bactericide.The agricultural fungicides of being produced by alkaloid of sophora flavescens ait is to the person poultry harmless, environmentally safe.
Tea Saponin (Tea saponin, TS) be from the product-tea seed cake after the oil expression of oil tea (Camellia oleifera), tea seeds such as (C.sinensis), to extract and get, belong to the pentacyclic triterpene plant sapogenin glycoside on the structure, have extensive use in many-sides such as medicine, agricultural chemicals, washing, cosmetics, papermaking, ore dressings.Early stage Tea Saponin was once done soil pesticide and was extensive use of, and oil tea cake leachate has the better prevention effect to oncomelania, fly maggot, hookworm and rice blast, the rice sheath blight etc.Be suitable for emulsifier, synergist and the stabilizing agent of used as pesticides.
The objective of the invention is to develop the plant insecticide agricultural chemicals of a class based on Meliaceae plant extracts nimbin, leguminous plant extract alkaloid of sophora flavescens ait.Remedy single plant extracts as insecticide deficiency in use to reach; Urge the long weak point of mending mutually with being mixed of many sections various plants extract, improve result of use, enlarge the scope of application, reduce use cost.
Technical scheme of the present invention: plant insecticide is made up of the composition of following weight ratio:
Nimbin 0.1-90% oxymatrine 0.1-98%
Other plant extracts of matrine 0.1-98% 0-50%
All the other are auxiliary agent.
Other plant extracts is a Tea Saponin.
Said preparation can be diluted to the spray agent that contains nimbin 0.1-1000PPM, oxymatrine 0.1-1000PPM and matrine 0.1-1000PPM concentration.
Said preparation can be made into emulsion, aqua, aqueous emulsion, colloidal suspending agent, soluble powder and wetting powder.
The preparation method of plant insecticide measures the content that prints chinaberry seed marc, the leguminous plant raw material that is rich in alkaloid of sophora flavescens ait and the nimbin in other plant material, oxymatrine, matrine, other plant extracts earlier; The content requirement of nimbin 0.1-90%, the oxymatrine 0.1-98% that sets in prescription, matrine 0.1-98%, other plant extracts 0-50% is determined the proportioning ratio of seal chinaberry seed marc, the leguminous plant raw material that is rich in alkaloid of sophora flavescens ait and other plant material and is mixed then; Mixed raw material input is extracted equipment, extracts with solvent refluxing, stops extracting after being leached into the extraction content of regulation; Be evaporated to the liquid extract of specified quantity behind the extracting liquid filtering; In the liquid extract that concentrates, add other auxiliary agent of setting by prescription; By standard testing, not meeting standard code as content can be adjusted to up to specification with nimbin elaboration, alkaloid of sophora flavescens ait elaboration, other other plant extracts elaboration.
The present invention has the following advantages and effect:
1, after nimbin and alkaloid of sophora flavescens ait and other plant extracts are mixed, both can overcome the slow shortcoming of seal chinaberry insecticide effect, the advantage that can keep printing chinaberry insecticide long action time again.
2, nimbin and alkaloid of sophora flavescens ait all are botanical pesticides, and being mixed between them kept botanical pesticide low toxicity, efficient, easily degraded, noresidue, to insect be difficult for developing immunity to drugs, advantage free from environmental pollution.
3, being mixed of nimbin and alkaloid of sophora flavescens ait and other plant extracts can enlarge the prevention and treatment range to agricultural pest, and can make it to become one is insecticide, is again bactericidal agent, but also is the novel agrochemical formulations of antivirotic.
