Further Information

Modest systemic activity. According to Dow (2014), foliar formulations of spinosad are modestly systemic, with more movement and penetration observed with younger and rapidly growing leaves. Limited root uptake may also occur under certain conditions and environments. Spinosad is used as a larvicide in mosquito control.
