Abstract

Northern corn leaf blight, incited by Exserohilum turcicum, is one of the most important foliar diseases of sweet corn (Zea mays). Causing large elliptical lesions that may coalesce and result in significant levels of leaf necrosis, fungicides are frequently relied upon for control. Two field experiments were conducted in south
Florida during Spring 2008 to evaluate the efficacy of several triazole and strobilurin fungicides, alone and in pre-mixtures, for control of this fungal pathogen. The experimental design consisted of four replications of 10 fungicide treatments arranged in randomized complete blocks.
