Description and mission

Plant pathology is the study of plant diseases, their cause, effects, and control. The discipline is closely integrated with the other biological sciences, and we have unique strengths in basic and applied research.

Departmental research and teaching emphasis

  • The major field crops in Kansas: wheat, corn, sorghum, alfalfa, and soybeans, plus horticultural plants (trees, turf, vegetables, fruits).
  • The major pathogen groups: bacteria, fungi, nematodes, and viruses. Molecular genetics is a departmental strength.
  • Specialty areas: bioinformatics; biological control; cell and tissue culture, plant transformation and regeneration; disease diagnostics; disease management; disease physiology; epidemiology; host/parasite genetics, cytogenetics; microbial ecology; microbioal genetics.

Our Department administers the campus-wide Plant Biotechnology Center and Integrated Genomics Faculty; the 9-state, Great Plains Diagnostic Network; and the Wheat Genetics Resource Center, which is international in scope.

Invited seminars

Our Department has an exceptionally strong invited seminar series, averaging 18 speakers per year from universities, research centers, government agencies, and private industry around the world. All seminars are open to the rest of the academic community and to the public. Seminars are presented throughout the year.


Our Department currently has 23 state faculty, 7 adjunct faculty, 35-40 graduate students, about 25 post-doctoral fellows and visiting scientists, and about 20 technical assistants, who come from 20 countries on 5 continents. We are a diverse Department with a global climate in which ideas thrive and people excel.

Facilities and equipment

Our Department has 39,000 sq. ft. of modern office, laboratory, and classroom space, most on the top floor of a 4-story building that is attached to 100,000 sq. ft. (2.3 acres, or about 1 hectare) of greenhouse space. This has been described as the largest university plant science complex in the country. Faculty have individual research labs, all well-equipped for the types of research they do. We share equipment, materials, and ideas across the Department.

Degree options

The department offers a full range of courses leading to the M.S. and Ph.D. degrees. These cover diseases caused by bacteria, fungi, nematodes, and viruses; bacterial and fungal genetics; disease control, diagnosis, ecology, epidemiology, and physiology; host plant resistance to disease; plant pathology methods; plant tissue culture and regeneration; plant cytogenetics; and student seminar, special problems and topics, and research.

For students coming into our program, we like to see background coursework in the biological sciences (such as botany or biology, plant pathology, entomology, mycology, microbiology, genetics); chemistry (such as inorganic, organic, biochemistry); mathematics; physics; statistics; and soil science or geology. Some coursework to remedy background deficiencies can be taken along with graduate courses, and some of this can be taken for graduate credit. Grades in relevant courses should be A or B, with an overall grade point average of at least B. We do not require a GRE score.

Ph.D. students in Plant Pathology are required to take a class on each of the four major pathogen groups, a course in the molecular biology of plants and/or their pathogens, a course in community level biology as related to plant pathology, and to have a significant teaching experience.  M.S. students take a subset of the classes taken by Ph.D. students.  Courses taken in a M.S. program generally are applicable to a Ph.S. in Plant Pathology if the student selects the thesis option.  Coursework requirements are listed on our departmental homepage at:

Some of our faculty also participate in the interdepartmental program in Genetics, described elsewhere, which leads to a degree in Genetics.


Applications are accepted at any time of the year, and graduate studies can begin during fall, spring, or summer terms. Applying early increases the probability of being awarded an assistantship. Application blanks can be obtained from the Department and from the Graduate School. All application materials should be sent to the department.

Financial Assistance

Financial support may be available to qualified students, with priority to U.S. students. Departmental graduate research assistantships for 2008-2009 are $20,900 for students working toward an M.S. degree and $21,900 (Tillman Scholarships at $24,400) for students working toward a Ph.D. degree; assistantships increase about $400 per year. Out-of-state (but not in-state) tuition is waived with either of these appointments. All applications are evaluated for available assistantships. Students may also be eligible to apply for fellowships from private and federal sources. In addition, a new College of Agriculture Doctoral Tuition Scholarship program for outstanding students entering the Ph.D. program, when available, pays the student’s tuition and fees at the time of enrollment and continues throughout the student’s doctoral program, as long as they maintain good academic standing.

Departmental assistantships are limited to 30 months for M.S. from B.S., 48 months for Ph.D. from M. S., and 60 months for Ph.D. from B.S. degree. Duration of assistantship from grants and other sources is determined by the faculty member in charge. Continuation of all assistantships depends upon continued satisfactory progress toward the degree and availability of funding.

All students on half-time assistantships are required to enroll in at least 6 credit hours during each regular semester and 1 credit hour during the summer. Research hours can be taken as needed to fill in these credits. This requirement will be waived during the semester in which the degree is granted, although students must be enrolled in enough credits during that semester to meet University requirements.

Although there are no formal GTAs in plant pathology, all graduate students assist in teaching at least one course in the department during their graduate studies and receive credit for their efforts by enrolling for one or two credits of PLPTH 922.

Students on departmental assistantships are expected to serve as teaching assistants in departmental undergraduate courses (numbered below 699) as needed, but not more than once each year.

Students whose native language is not English are required to first score at the appropriate level on an English comprehension test administered by the English Language Program at K-State.
