Christina.Hagerty@oregonstate.edu

Research Interests
I am focused on serving the producers and stakeholders of high quality PNW wheat. My goal is to conduct relevant, practical, and applied research on the biology and control of plant-pathogenic fungi, viruses, and nematodes that limit yields of dryland wheat production in the Inland Pacific Northwest. My program is currently funded by the Oregon Wheat Commission, the Washington Grain Commission, USDA-ARS, The Oregon Ag. Experiment Station, and industry partners.
