Detecting Plant Diseases in the Lab

The Hermiston Agricultural Research and Extension Center in Hermiston, Oregon has a full- service, plant pathology diagnostic lab that serves the growing needs of the agricultural community in the Columbia Basin. The lab receives all types of plant disease samples including diseases of potatoes and other vegetables, trees, and ornamentals, and diseases spread by insect vectors. We use a variety of testing methods, ranging from traditional culturing techniques for fungi and bacteria to advanced molecular techniques that use pathogen DNA sequences to identify pathogens and diagnose diseases. The Hermiston Agricultural Research & Extension Center is located at 2121 South First Street in Hermiston, Oregon. Office hours are 8:00am - 5:00pm, Monday - Friday, closed during the lunch hour, noon - 1:00pm.
