Prepping Fields to Reduce Winter Injury
Winter injury can be a significant issue in northern climates, resulting in declines in playability and turf quality as well as costly reestablishment. Topics for discussion will include the major causes for winter injury in grasses used for sports turf, physiological mechanisms important for turfgrass overwintering and freezing tolerance, as well as the effects of various pest and disease management practices on improving turfgrass growth and winter conditioning.
Michelle DaCosta, Ph.D.
Associate Professor of Turfgrass Physiology
Stockbridge School of Agriculture
Dr. DaCosta’s research program is centered on gaining greater insight into physiological mechanisms of plant adaptation to environmental stresses, using perennial grasses as an experimental system. Our goal is to identify plant traits and stress response pathways associated with tolerance to different environmental stresses that are relevant in terms of global climate change, including temperature extremes and drought. In addition to addressing fundamental questions on mechanisms of abiotic stress resistance, we also conduct applied research to help guide turf industry professionals on the selection of stress-resistant grass species and cultivars, and to aid in the development of best management practices aimed at reduced water, fertilizer, and pesticide use.
