Target Spot is a foliar disease in cotton that occurs occasionally and sporadically in North Carolina.  This disease causes lesions on leaves and eventually causes defoliation especially of lower leaves and can lead to reductions in yield.  The objectives of this research were to investigate the effects of Target Spot in cotton in a field with a history of severe disease pressure, to investigate the effects of fungicide application on disease incidence, progression, and yield, and to determine if one or multiple applications of fungicide are warranted in order to adequately control the disease.
