View the Labels/SDS information for Ference Insecticide.
Ference® insecticide contains the active ingredient, cyantraniliprole, which will raise the bar on season-long control of ABW (annual bluegrass weevil). Since Ference systemically controls all larval stages, it provides superintendents greater flexibility later in the year when ABW populations are asynchronous. Ference will provide increased and extended control of ABW through the enhanced Syngenta Optimum Control Strategy, found on WeevilTrak.com.
