Summary of the invention
The object of the invention is to develop a kind of binary pesticide composition containing compd A, to meet the demand that agricultural and pest control aspect, urban health field day by day improve insecticide effect and kind is constantly updated.
Technical scheme of the present invention is as follows:
A kind of binary pesticide composition, 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 pesticide composition 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 determination of activity demonstrates binary pesticide composition of the present invention and has good synergistic effect.Active component two in composition both can be indoxacarb (i.e. the mixture of S isomer and R isomer) also can be smart indoxacarb (100%S isomer).Because R isomer does not have activity, when using indoxacarb as active component two, active ingredient is with S isomer.
Composition of the present invention can provide in finished product preparation form.Therefore, the present invention also comprises a kind of insecticides of dosage form.Take binary pesticide composition as active component, make missible oil, suspending agent, water-dispersible granules, aqueous emulsion, soluble liquid, wetting powder, oil-suspending agent etc. as required.In composition, the cumulative amount of active component is between 0.5% ~ 95%, and preferred cumulative amount is between 1%-85%.In composition of the present invention, the content of active component depends on amount of application when being used alone, and 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 prepared by common processing method, after mixing with liquid-carrier (solvent) or solid carrier by active substance, add one or more surfactants as emulsifier, dispersant, wetting agent, adhesive, stabilizing agent and defoamer etc.Containing at least one carrier and at least one surfactant in usual composition.In all cases, should guarantee that present composition active component is uniformly distributed.
