Plant Pathology, Physiology, a (PPWS)

PPWS 2004 - Mysterious Mushrooms, Malicious Molds (3 credits) 

Study of the fungi and their close relatives, with special attention to their roles in the natural world and in shaping the course of human history. Historical and practical significance of fungi as sources of medicine, pathogens of plants and animals, rotters and decayers of organic matter, makers of food and drink, manufacturers of dangerous toxins, and producers of mind-altering chemicals. A student must have a basic understanding of biology.

Pathway Concept Area(s): 4 Reasoning in Natural Sci., 11 Intercultural&Global Aware. 
PPWS 2754 - Weeds That Shape Our World (3 credits) 

How weeds shape our world, and why society will never get rid of them. Introduction to weed identification, weeds in their socio-cultural, environmental, and economic context. Consideration of the tension among their beneficial aspects, control, human attitudes, and the ethical dilemmas they post to society.

Pathway Concept Area(s): 4 Reasoning in Natural Sci., 10 Ethical Reasoning 
PPWS 2964 - Field Study (1-19 credits) 
PPWS 2984 - Special Study (1-19 credits) 
PPWS 2994 - Undergraduate Research (1-19 credits) 
PPWS 4104 - Plant Pathology (4 credits) 

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 studied as examples to illustrate general principles.

Prerequisite(s): (BIOL 1005 or BIOL 1105) and (BIOL 1006 or BIOL 1106) 
PPWS 4114 - Microbial Forensics and Biosecurity (3 credits) 

Concepts of comparative and evolutionary genomics for pathogen characterization and identification taught through case studies of bioterrorism, involuntary and voluntary disease transmission, infectious disease epidemics, and genetically modified organisms; emphasis placed on unambiguous source attribution of a disease outbreak to a particular microbe, risk assessment, response as individual, community, and nation to a bioterrorism attack or disease outbreak, federal biosecurity regulations, and career opportunities.

Prerequisite(s): BIOL 2604 and (BIOL 2104 or BIOL 2004) 
PPWS 4154 - Plant Problem Diagnosis (3 credits) 

Plant problem diagnosis in the laboratory and field, including recognition of disease, insect and abiotic (nonliving) problems, as well as the major groups of plant pathogens of a variety of regionally important horticultural and agronomic crops. General management options for pests and pathogens.

Corequisite(s): PPWS 4104 
PPWS 4264 - Pesticide Usage (3 credits) 

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.

Cross-listed: ENT 4264 
PPWS 4504 - Fundamentals of Plant Physiology (3 credits) 

Fundamental principles of plant physiology (photosynthesis, respiration, transpiration, nutrition, translocation, and development) will be integrated with discussion of the relationship between abiotic environmental factors and plant physiological processes. Both agricultural and non-crop plants will be emphasized.

Prerequisite(s): (BIOL 1006 or BIOL 2304) and CHEM 1036 
PPWS 4604 - Biological Invasions (3 credits) 

Broad overview of the causes, consequences, and epidemiology of invasive plants, animals, and microbes. Conceptual, mechanistic, societal, and political components of invasive species from Darwin to modern day, covering the invasion process from introduction to ecological or economic impact. Taxonomy, management, and risk assessment will be covered via case studies, within a policy context.

Prerequisite(s): BIOL 1105 and BIOL 1106 
PPWS 4754 - Weed Science: Principles and Practices (3 credits) 

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.

Prerequisite(s): BIOL 2304 and CHEM 1036 
PPWS 4964 - Field Study (1-19 credits) 
PPWS 4974 - Independent Study (1-19 credits) 
PPWS 4984 - Special Study (1-19 credits) 
PPWS 4994 - Undergraduate Research (1-19 credits)
