Overview

  • The primary mission of the department is research, extension and graduate education in the areas of plant pathology (nature, biology and control of plant diseases), plant physiology, and weed science (weed control, action of herbicides). No undergraduate majors are offered in these areas; students with an interest in plant pathology or weed science may enroll in the Departments of Crop and Soil Environmental Sciences or Horticulture. The department offers several undergraduate courses that may be required or electives for students in agricultural or biological majors. These courses are designed to furnish basic knowledge of the nature, diagnosis, and control of plant diseases; identification and control of weeds; plant metabolism, nutrition, and growth regulation; and modern pest management and pesticide usage.
  • The department offers graduate programs leading to M.S. in the life sciences and Ph.D. in plant pathology, plant physiology and weed science. A non-thesis M.S. program in plant protection and pest management is also available (see Graduate Catalog).

Undergraduate Course Descriptions (PPWS)

2104: DOMESTICATING THE GENE
This course explores how and why humans have manipulated plan genomes from prehistory through the current genomic era by examining the scientific, cultural, historical, and legal aspects of plant gene management in both conventional and transgenic crops. Pre: BIOL 1005 or BIOL 1105. (3H,3C)

2964: FIELD STUDY
Variable credit course.

2984: SPECIAL STUDY
Variable credit course.

3104: PLANT PATHOLOGY
Introduction to plant pathology as a science and a crop protection discipline. Plant disease diagnosis, biology and identification of plant disease causing agents, factors leading to disease build-up, and management of plant diseases. Diseases of specific crops are discussed as examples to illustrate general principles. Pre: BIOL 1005, BIOL 1006. (3H,3L,4C) I.

3444 (BIOL 3444): EXPLAINING MOLECULAR CELL BIOLOGY
This writing-intensive course will enable students to improve both their own scientific writing and their understanding of the writing of specialists, scientists in other fields and lay readers. Topics include bacterial, plant, biomedical examples of major advances in molecular cell biology and biotechnology. Includes a review of current methodologies, in-class writing workshops and problem-solving sessions, mock press conferences, individual and team presentations, and individual conferences with the instructor. Pre: BIOL 2104. (3H,3C) II.

3505, 3506: PLANT PHYSIOLOGY AND THE ENVIRONMENT
Fundamental principles of plant physiology (photosynthesis, respiration, transpiration, nutrition, translocation and development) will be integrated with: abiotic (3505, water, nutrient, salinity, temperature, light, mechanical and air pollutant stresses) and biotic (3506, plant pathogens, herbivores, parasitic plants, weeds) environmental factors relative to their effects on plant physiological processes. Interaction of the abiotic and biotic environments as they influence the physiology of both natural and agricultural plants will be emphasized. Pre: (BIOL 1106 or BIOL 2304), (CHEM 1036). (3H,3C) 3505: II; 3506: I.

3514: PLANT PHYSIOLOGY LAB
A laboratory course designed to illustrate basic physiological principles related to nutrient deficiencies, membrane permeability and composition, water/nutrient absorption and translocation, transpiration, photosynthesis, physiological functions of growth regulators, enzyme activity, and elemental composition of plant tissue. Co: 3504. (3L,1C) II.

4264 (ENT 4264): PESTICIDE USAGE
An interdisciplinary study of pesticides used in urban and agricultural environments. Topics studied will include: classification, toxicology, formulation, application techniques, safety, legal considerations, environmental impact, and research and development of new pesticides. Pre: CHEM 2515 or CHEM 2536. (2H,3L,3C) II.

4524 (ENT 4524) (FOR 4524): PEST AND STRESS MANAGEMENT OF TREES
Ecology of biotic and abiotic influences on forest and landscape tree health. Emphasis will be placed on developing a theoretical and practical understanding for managing pests and stresses of trees in both the forest and landscape setting. Insects and diseases of trees will be reviewed. Pre: FOR3324 or PPWS 3104 or FOR 3354. (2H,3L,3C) II.

4754: WEED SCIENCE: PRINCIPLES AND PRACTICES
Weeds and human affairs; costs and losses; emphasis on weed biology, weed identification and weed-crop ecology; agronomic, physiological, and chemical principles underlying prevention, eradication, and control of undesired vegetation; methods of weed control available for modern agronomic, forestry, horticultural, and non-crop situations. Pre: BIOL 2304, CHEM 1036. (2H,3L,3C) I.

4964: FIELD STUDY
Variable credit course.

4974: INDEPENDENT STUDY
Variable credit course.

4984: SPECIAL STUDY
Variable credit course.

4994: UNDERGRADUATE RESEARCH
Variable credit course.
