Diseases of specialty crops


Fund, design, and conduct research projects that address the etiology, spread, and applied management of new and/or important diseases of specialty crops in the Panhandle of Nebraska, with an emphasis on sugar beet, dry bean, and sunflower diseases.


Develop and deliver statewide and regional educational publications and programs involving diseases of specialty crops – including sugar beets, dry beans, sunflowers, potatoes, chickpeas and other pulse crops, proso millet, chicory, grass seed, edible amaranths, bio-fuel crops like brown mustards, camelina, and canola, and other newly emerging alternative crops.
