Plant Pathology & Crop Physiology

The Department of Plant Pathology and Crop Physiology is recognized nationally and internationally for applied and basic research on economically important agricultural crops. Climactic conditions in Louisiana allow cultivation of and research on semitropical crop species such as rice, sugarcane, cotton, sweet potatoes, and soybeans. Through our extension services, we conduct research and assist Louisiana farmers in the management and control of plant disease.

Our graduate program presents students the opportunity to work with Louisiana Agricultural Experiment Station personnel who conduct investigations in areas of plant pathology, crop physiology and plant molecular biology. M.S. and Ph.D. graduates of the department are prepared for challenging careers in agricultural research at universities, governmental and private agencies.
