Summary of the invention
The object of the invention is to develop a kind of binary insecticides that contains compd A, the insecticide effect is day by day improved to satisfy agricultural and pest control aspect, urban health field the demand of constantly updating with kind.
Technical scheme of the present invention is as follows:
A kind of binary insecticides, active component one is selected from compd A, and active component two is selected from indoxacarb or smart indoxacarb; Described compd A has following structure:
In binary insecticides of the present invention, the ratio of weight and number of two kinds of active components is 1: 99~99: 1, is preferably 1: 20~20: 1.
Indoor biological activity determination demonstrates binary insecticides of the present invention and has good synergistic effect.Active component two in composition can be both that indoxacarb (being the mixture of S isomer and R isomer) can be also smart indoxacarb (100%S isomer).Because the R isomer does not have activity, when using indoxacarb as active component two, active ingredient is in the S isomer.
Composition of the present invention can be the finished product preparation form to be provided.Therefore, the present invention also comprises a kind of insecticides of dosage form.Take the binary insecticides as active component, make as required missible oil, suspending agent, water-dispersible granules, aqueous emulsion, soluble liquid, wetting powder, oil-suspending agent etc.In composition, the cumulative amount of active component is between 0.5%~95%, and preferred cumulative amount is between 1%-85%.Amount of application when in composition of the present invention, the content of active component depends on independent the use also depends on mixed ratio and synergistic effect degree.The optimum range of active component content is different according to the preparation type of composition.
The preparation of composition finished product preparation of the present invention can be by common processing method preparation, after being about to active substance and liquid-carrier (solvent) or solid carrier mixing, add one or more surfactants such as emulsifier, dispersant, wetting agent, adhesive, stabilizing agent and defoamer etc.Usually contain at least a carrier and at least a surfactant in composition.In all cases, should guarantee that present composition active component evenly distributes.
Missible oil contains 10~50% active component usually, 2~20% emulsifier, 0~20% other additives such as stabilizing agent, bleeding agent, corrosion inhibitor etc., and solvent (also containing in case of necessity cosolvent).

Wetting powder contains 10~85% active component usually, except solid inert carrier, usually contains 3~10% dispersant, can also contain 0~10% stabilizing agent and (or) other additives, for example bleeding agent or sticker.
Aqueous emulsion is that former medicine, organic solvent, surfactant mixing are formed oil phase, and water, antifreezing agent are mixed, and becomes the transparent and homogeneous water.With high-shear emulsion machine high speed shear oil phase, slowly water is added oil phase simultaneously, common active ingredient 1~60%, surfactant 5~20%, antifreezing agent 2~10%, water surplus.
Microemulsion is that former medicine, organic solvent, surfactant, water are mixed, and becomes the transparent and homogeneous water.Common active ingredient 1~50%, surfactant 10~40%, antifreezing agent 2~10%, water surplus.
Soluble liquid is that active component, organic solvent, surfactant are mixed, and becomes transparent and homogeneous liquid.Common active ingredient 1~50%, surfactant 6~20%, organic solvent surplus.
Oil-suspending agent is with having active component, surfactant, oil base carrier to add sand milling in sand mill, until particle diameter is qualified, and common active ingredient 2~60%, surfactant 6~20%, oil base carrier surplus.
Moisture dispersion liquid and emulsion (composition that missible oil as of the present invention in dilute with water, wetting powder or concentrate obtain) are also within the scope of the invention.Above-mentioned emulsion can be water-in-oil type or oil-in-water type, can have dense thick pulpous state denseness.
