Plant Pathology Department Website

The Department of Entomology and Plant Pathology offers a minor in plant pathology, the study of interrelationships of plants with the abiotic and biotic agents that affect plant health and productivity. The goal of the discipline is to minimize the impact of plant diseases on agricultural production and human health. Scientific training within the department focuses on the nature, cause, and management of plant diseases.

Plant pathology is offered as a graduate degree program. Undergraduate students interested in plant pathology should pursue a minor in pest management or plant pathology. See Pest Management for degree requirements.

PLPA 3004. Principles of Plant Pathology. 4 Hours.

Examination of the causes and symptoms of plant disease and the genetics of plant disease. Physiology, and ecology of host-pathogen interactions. Spread of disease and principles of disease control. Corequisite: Lab component. (Typically offered: Fall)
This course is cross-listed with BIOL 3004.

PLPA 400V. Research. 1-6 Hour.

Original investigations of assigned problems in plant pathology. Prerequisite: PLPA 3004. (Typically offered: Fall, Spring and Summer)

PLPA 4123. Bacterial Lifestyles. 3 Hours.

The course will introduce students to bacteria as prokaryotic organisms, different from eukaryotes such as plants and animals. Model microbial systems will be studied in more detail to identify unique strategies that bacteria employ to thrive in their respective environment, whether they are causing diseases or establishing beneficial interactions with animal or plants or coexisting with other microorganisms in diverse ecological environments. The course will also cover special adaptations that bacteria have evolved to adapt to harsh environments and how these adaptations can be harnessed to control pollution. Prerequisite: (BIOL 2013 and BIOL 2011L) or BIOL 3123. (Typically offered: Spring Odd Years)
This course is cross-listed with BIOL 4223.

This course is cross-listed with BIOL 4133.

PLPA 4304. Applied Plant Disease Management. 4 Hours.

A plant pathology course emphasizing practical understanding of the concepts and principles of agronomic and horticultural crop disease management, including disease diagnosis, monitoring, and using models to forecast disease events. Prerequisite: PLPA 3004 or instructor consent. (Typically offered: Irregular)

PLPA 4333. Biotechnology in Agriculture. 3 Hours.
