Spinosad is not a systemic. it will not enter the plant and have residual effects on insects. it is applied to the plant and sunlight breaks it down rather quickly so a spreader sticker should be used when applying it.
As per a spinosad fact sheet..... "Spinosad is a natural substance made by a soil bacterium that can be toxic to insects. It is a mixture of two chemicals called spinosyn A and spinosyn D. It is used to control a wide variety of pests. These include thrips, leafminers, spider mites, mosquitoes, ants, fruit flies and others". no where does it say it is a systemic or can be used as a systemic.
