Identification and control of diseases impacting vegetable and seed crops; understanding impacts to soilborne pathogens following fumigation; diseases caused by Phytophthora sp.; Identification and control of Potato diseases.

  • Virus, nematodes and fungal pathogens are responsible for extensive losses in the important vegetable growing region of the Columbia Basin in northeast Oregon and eastern Washington. My research is centered around the identification of the specific pathogens and understanding their lifecycle and then their control through cultural manipulation and/or through chemical and biotechnical methods.
