The residual activity of six concentrations of chlorpyrifos, spinosad, and halofenozide on fall armyworm, Spodoptera frugiperda (J.E. Smith), as mediated by five different turfgrass cultivars expressing varying levels of resistance was evaluated in greenhouse trials. Similarly, varying concentrations of halofenozide were applied to six turfgrass cultivars in the field and mortality of neonate and third instar fall armyworms was assessed.
