Abstract
The present invention relates to the field of natural insecticide. In the present invention, various additives in certain proportion are added to nimbin and neem oil as mainly insecticidal active ingredients for preparing preparations in the form of nimbin emulsifying oil, wettable powder and a suspending agent. The preparations are plant insecticidal nimbin preparations with the advantages of high efficiency, low toxicity, no toxic residue and no damage to people and livestock, and has good preventing effects on various insect pests, such as diamond black moths, yellow flea beetles, cabbage caterpillars, etc. The preparations are particularly suitable for preventing and eliminating various insect pests with resistance.
Description
The invention belongs to the natural insecticide field, be specifically related to how will print the insecticide that the main activity of extracting the chinaberry (Azadirachtaindica A.Juss) is mixed with heterogeneity content from plant.
Utilize that the exploitation of natural pesticide plant is efficient, low toxicity, vegetable insecticide free from environmental pollution be subjected to people's great attention just gradually.In numerous pesticide plants, research at most, the most influential seal chinaberry plant that will count the Meliaceae Melia.This plant is the efficient insecticide plant that the world today generally acknowledges, extensively plants in the torrid zone, subtropics, is a kind of can the growth fast and arbor that the four seasons are green for a long time.Studies show that in a large number that both at home and abroad contain multiple insecticide active substance in the positions such as seed, leaf, bark and branch of seal chinaberry, wherein the insecticidal activity with nimbin is the strongest.
Current, the countries in the world scientist is in the research of being devoted to the nimbin pesticide product, and states such as the U.S., Germany, India, Canada successively develop product such as Margosan-O (U.S.'s product), Neemark (India's product) etc. put on market.These product forms have formulations such as missible oil, granule, usually after dispenser in 1～5 day the control efficiency to insect comparatively remarkable, but control efficiency then obviously reduces after 5～6 days.Repeatedly medication of peasant will be forced like this, the increase of production cost certainly will be caused.Studies show that in a large number, nimbin is complicated macromolecular substances, many functional groups that can react are arranged in the molecular structure, comprise ester group, epoxy construction etc., when nimbin is in ultraviolet lighting, high temperature or water, very easily decompose, cause the insecticidal activity of nimbin to reduce, thereby on to control of insect, show relatively poor lasting effect.Though Larson (1985) reports that at United States Patent No 4,556,562 the pH value method of certain density nimbin preparations of preparation and adjusting preparation can delay the degraded of nimbin, actual effect is unsatisfactory; W.R.Grace (1994) also has similar simple report at United States Patent No 5,281,618, does not have substantive to solve that the nimbin product easily decomposes, unsettled method.In addition, nimbin is subject to pollutions such as aflatoxins and influences its storage-life in process, and there are shortcomings such as difficult emulsification, nimbin product forms is comparatively single in process of production in nimbin emulsion.As the simple preparation at United States Patent No 5,405,612 report nimbin emulsions such as James.C.Locket (1995), but the system of failing solves this type of problem.For a long time, above-mentioned factor has restricted the production of nimbin product and the large tracts of land on agricultural is promoted the use of.
The object of the present invention is to provide the plant-type nimbin insecticide that formulation is various, prescription is original, easily decompose in order to solve nimbin, difficult storage, difficult emulsification, easily pollute, formulation is single, to the defective of insect lasting effect difference, and can satisfy the needs that various pests is prevented and treated in the agricultural production.
The object of the present invention is achieved like this: to pulverize neem seed is raw material, selects for use methyl alcohol or ethanol for extracting solvent, extracts active substance nimbin and neem oil under the temperature condition certain extraction.Again these active substances are mixed with the nimbin preparation of missible oil, wetting powder and three kinds of different dosage forms of suspending agent by certain material proportion.These three kinds of medicine in different forms are to be main insecticidal constituent with nimbin and neem oil, allocate surfactant, cosolvent, sun-screening agent, preservative, stabilizing agent, synergist, organic solvent, penetrating agent, pH value conditioning agent into and are mixed with the nimbin emulsion preparation; Allocate wetting agent, dispersant, preservative, filler into and be mixed with nimbin wettable powder agent formulation; Allocate wetting agent, dispersant, tackifier, stabilizing agent, antifreezing agent, preservative, defoamer, organic solvent and water into and be mixed with nimbin suspending agent preparation.Adding surfactant and cosolvent in the preparation nimbin emulsion can make preparation keep good emulsifying effect and solvability; The adding sun-screening agent can greatly reduce the light degradation power of nimbin, improves the lasting effect of medicament to insect; Add stabilizing agent and can make nimbin keep stable in water or under the Acidity of Aikalinity condition, improved the storage-life of preparation; Add preservative and can effectively prevent and kill off endotoxin contaminations such as aflatoxins; Add synergist and penetrating agent and can strengthen the killing power of medicament insect; Add organic solvent energy lytic activity material and other batchings; Adding pH value conditioning agent can make cream preparation remain in certain acid-base value scope.Adding wetting agent and dispersant in nimbin wettable powder agent formulation can make preparation good dissolving power and adhesive force be arranged converting when water is used; Add filler and can improve the wetting powder grain fineness.It is identical to add the effect that adds in wetting agent, dispersant, stabilizing agent, preservative, organic solvent and missible oil and the wettable powder agent formulation in nimbin suspending agent preparation; Adding tackifier and defoamer can make the physical behavior of preparation such as color etc. keep good; Add a certain amount of water and help the dissolving of other batchings.
