Field and laboratory evaluations of broflanilide for management of wireworms in sugarcane

Wireworms (Coleoptera: Elateridae), primarily Melanotus communis, damage sugarcane produced in Florida by feeding on belowground vegetative seed pieces after planting. This feeding results in a decrease in plant population, which decreases harvested sugarcane tonnage. Wireworm management with insecticides has relied on the application of phorate, a highly hazardous organophosphate. Broflanilide is a novel insecticide in the meta-diamide class that might represent an alternative to phorate in Florida sugarcane. Plant population data collected 4 to 13 weeks after planting in on-farm evaluations conducted in 2022 and 2023 suggest that brofanilide decreases sugarcane stand loss caused by wireworms. In addition, a laboratory bioassay using a research spray booth determined the effect of broflanilide on M. communis mortality. The potential role of broflanilide in sugarcane insect pest management will be discussed.
