Joseph Vargas, Ph.D.
Overview of current program:
We focus on turfgrass disease management by chemical, biological, and genetic means. We have discovered and registered a Pseudomonas bacterium for biological control of turfgrass diseases and are currently trying to expand its use into other areas. We have developed turfgrass disease preditiction models for three turfgrass diseases and are currently modifying them under field conditions. We have an active turfgrass disease breeding program to develop disease resistant creeping bentgrass cultivars.
