Fall armyworm research, development and extension for horticulture

The testing results to date indicate no change in susceptibility to chlorantraniliprole, emamectin benzoate, spinetoram or indoxacarb in FAW populations from Queensland, Western Australia, Northern Territory and New South Wales. Insecticide resistance surveillance is a critical component of FAW management, enabling early detection of changes in susceptibility and informing strategies to minimise the risk of resistance-driven control failures. Our surveillance program utilises F2 screening for early detection of resistance to key selective insecticides registered for FAW control, including indoxacarb, emamectin benzoate, spinetoram and chlorantraniliprole. Results provide practical insights which will support growers in optimising their spray programs. Importantly, integrating rapid detection of resistance combined with the adoption of best management practices will be key to reducing the resistance risk in horticulture and other industries impacted by FAW.
