The ecology of turfgrass diseases and cultural methods of management will be emphasized, in addition to field recognition and microscopic diagnosis of diseases. Advances in biological and chemical control measures, and their impact on turfgrass ecosystems and surrounding environments will also be discussed. This course will interest students who plan a career in turfgrass management, but will also be useful to those interested in maintaining healthy home lawns.

Class Schedule and Location:
This course covers the biology and management of turfgrass diseases and disorders emphasizing their ecology and cultural, biological and chemical means of control. Laboratory identification and field recognition of common turfgrass diseases are discussed, along with the impact of control methods on the environment. Recent research on turfgrass diseases is also presented.
Specific Learning Outcomes:
- To describe major groups of cool season (northern temperate zone) turf diseases;
- To properly identify causal agents in turf disease samples using a diagnostic manual and a microscope;
- To recognize the effects of environmental conditions on turf diseases;
- To recognize the impact of turf disease management practices on the environment;
- To differentiate between biotic and abiotic disease symptoms; and
- To use cultural, biological and chemical techniques to minimize severity of turfgrass diseases.
