Tiger grass is a popular ornamental grass grown throughout landscapes in South Florida. In the summer of 2006, a leaf spot was observed on tiger grass in the landscape and a commercial nursery in Homestead, FL. At high inoculum densities, symptoms were apparent as early as 12 h after inoculation, and caused widespread necrosis. This newly discovered disease could potentially have a dramatic effect on the aesthetic quality and salability of this landscape ornamental.
