Degree Conferred:

M.S. (PLPA)

Areas of Concentration: Fungal ecology and genetics, nematology, virology, soil ecology, molecular biology of plant pathogens,
biological control of plant diseases and weeds, genetics and physiology of parasitism and resistance, plant disease control, and diseases of cotton, fruits, rice, soybean, turfgrass, vegetables and wheat.

Prerequisites to Degree Program: Although no specific prerequisites are required, a strong background in agricultural, biological and physical sciences is desirable. Deficiencies or prerequisites for advanced courses may be included in the student's program.

Requirements for the Master of Science Degree: A thesis reporting results of original research and a minimum of 24 semester hours of course work (including 15 semester hours in plant pathology) plus 6 semester hours of thesis credit are required. The student must pass an oral examination after the thesis is completed.

The Ph.D. program in Plant Science is an interdepartmental doctoral program involving the Departments of Plant Pathology and Horticulture. Most of the course work and the dissertation research may be completed in Plant Pathology.
