  • Dynamics of Zymoseptoria tritici Fungicide Resistance in the Willamette Valley of Oregon

    Creator:
    Hagerty, Christina H.
    Abstract:
    The development of resistance to multiple fungicide classes is currently limiting disease management options for many pathogens, while the discovery of new fungicide classes has become less frequent. To address this pressing issue, a three-part study with different layers of complexity, objectives, and experimental approaches was conducted using the model...

  • Effects of host resistance on Mycosphaerella graminicola populations

    Creator:
    Cowger, Christina
    Abstract:
    Mycosphaerella graminicola (anamorph Septoria tritici) causes Septoria tritici blotch, a globally important disease of winter wheat. Resistance and pathogenicity generally vary quantitatively. The pathogen reproduces both sexually and asexually, and the pathogen population is highly genetically variable. Several unresolved questions about the epidemiology of this pathosystem are addressed by this...
