Research: 

My name is Joseph Roberts and I am a PhD student working in the Turf Pathology lab here at NC State.  I am a North Carolina native and received undergraduate degrees in Biological Sciences and Chemistry from NC State in 2007. After completing my undergraduate studies, I went on to obtain a Master’s degree in Plant Biology and Pathology from Rutgers University in 2009. My masters work focused on the influence of cultural management on the development of anthracnose in annual bluegrass putting greens.  I returned to NC State in 2010 to work on my PhD.  My current research focuses on ideas into the cause of etiolation of creeping bentgrass putting greens and the development of management factors for preventing this emerging problem.  Much of my focus currently involves characterization of bacteria isolated from symptomatic creeping bentgrass.  Current field projects are examining the impact of biostimulants, plant growth regulators, and new fungicide/antibiotic compounds on etiolation of creeping bentgrass putting green turf.
