Develop applied diagnostic and control programs for plant diseases of tree fruits, nuts, berries, grapes, ornamentals/nursery, Christmas trees and turf.
Many fungal and bacterial diseases are a constant problem for fruit and ornamental/nursery production in Oregon. Pathogen biology and life histories are studied in the field and lab to improve disease control recommendations. Screening biologicals, pesticides, or cultural practices effective against these organisms is an ongoing need valuable to Oregon's growers. Information is delivered to clientele using the latest techniques and technologies including satellite systems and the World Wide Web.
