Exirel Insecticide (FMC Corporation) has recently received an expanded federal label which includes use in caneberries against spotted wing drosophila (SWD). While we are still waiting on the state label for Exirel in caneberries in North Carolina, we expect it be available for use during the 2019 growing season.

This new label expands the effective modes of action (MOA) available for use to manage spotted wing drosophila in caneberries. Exirel is a Group 28 MOA, and the other materials effective against SWD in caneberries include pyrethroids (Group 3), organophosphates (Group 1A), and spinosyns (Group 5). Importantly, Exirel has a 1 day preharvest interval (PHI), which allows for its use when caneberries are at the greatest risk of damage from SWD.
