Further preferred as technique scheme, it also contains surfactant 5~10wt%, sun-screening agent 1.2~2.5wt%, stabilizing agent 1.0~3.0wt%, preservative 1.0~1.2wt%, synergist content are 0.5~3.0wt%, pH regulator agent 0.1~0.2wt%, surplus is an organic solvent.
Further preferred again as technique scheme, sun-screening agent is selected from any one or two kinds of mixture in p-aminobenzoic acid, the castor oil; Stabilizing agent is selected from epoxidized vegetable oil, 2, any one or two kinds of mixture among the 6-di-t-butyl Pyrogentisinic Acid; Preservative is selected from any one or more the mixture in charcoal, active carbon, the aminobenzoic acid; Synergist is selected from any one or more the mixture in dregs of beans, chlorination fat, the Butacide; PH value conditioning agent is selected from any one or more the mixture in sodium hydroxide, potassium hydroxide, the hydrochloric acid; Organic solvent is selected from any one or more the mixture in methyl alcohol, ethanol, the acetone.
Further preferred again as technique scheme, neem extract content is 10wt% in this Recompounded pesticide, Banlangen content is 0.03wt%.
Another kind as technique scheme is preferred, and neem extract content is 1~10wt% in this Recompounded pesticide, and Banlangen content is 0.01~1wt%, and the formulation of this Recompounded pesticide is the water and milk formulation.
Further preferred as technique scheme, described Recompounded pesticide oil phase part is divided into neem extract, Banlangen, antifreezing agent, defoamer and organic solvent; Aqueous portion is sun-screening agent, stabilizing agent, preservative, synergist, synergist, pH value conditioning agent.
Further preferred again as technique scheme, surfactant is selected from nonionic class surfactant; The aqueous portion sun-screening agent is selected from any one or two kinds of mixture in p-aminobenzoic acid, the castor oil, stabilizing agent is selected from epoxidized vegetable oil, 2, any one or two kinds of mixture among the 6-di-t-butyl Pyrogentisinic Acid, preservative is selected from any one or more the mixture in charcoal, active carbon, the aminobenzoic acid, synergist is selected from any one or more the mixture in dregs of beans, chlorination fat, the Butacide, and pH value conditioning agent is selected from any one or more the mixture in sodium hydroxide, potassium hydroxide, the hydrochloric acid; Oil phase part organic solvent is selected from any one or more the mixture in methyl alcohol, ethanol, ethyl acetate, the solvent naphtha, and antifreezing agent is selected from one or more in ethylene glycol, the glycerine, and defoamer is selected from organosiloxane, polyethers etc.
In the technique scheme of the present invention, neem extract is that the kind benevolence of seal chinaberry (Azadirachta indica) is pulverized, after one or more degreasings in weakly polar organic solvent such as benzinum, n-hexane or the cyclohexane, refining forming behind polar organic solvent such as ethanol or methanol extraction again, wherein nimbin content is about 0.1~5wt%.
In the technique scheme of the present invention, Banlangen is to extract the alkaloids substance that obtains from Sophora alopecuroide (SopHora alopecuroide) or kuh-seng (SopHora flavescens).
The present invention has following beneficial effect:
The present invention utilizes neem extract and Banlangen as effective component, adds that a certain amount of auxiliary agent is prepared from again.Owing to be medicine non-chemically, so environmental protection; Confirm that through effect experiment it has good insecticidal action; Because the effective component of this medicine is to belong to natural drug, so insect is difficult to develop immunity to drugs.
