Richard Latin

Botany and Plant Pathology 

  • Professor
Lilly Hall Room 1-317

Current research efforts in the area of turfgrass pathology focus on the management of diseases on golf course, sports turf, and professional landscapes. Specific research projects include the following:

  • Factors that affect fungicide performance
  • Fungicide resistant pathogen strains
  • Epidemiology of dollar spot on creeping bentgrass
  • Weather-based systems for scheduling fungicide applications

The turfgrass pathology extension effort focuses on educational programs for professional turf managers. Part of the educational process involves field demonstrations that address the efficacy of various disease management practices. Another component involves formal educational presentations and workshops on turfgrass disease identification and control. The extension effort also involves turf disease diagnosis and the investigation of factors that contribute to disease outbreaks. The extension activities provide an educational opportunity for those of us in turf pathology, raising our awareness to the concerns of turf managers so that we may target our research accordingly.
