The following description is for the course offering in Fall 2018 and is subject to change. It is provided for information only. The course outline distributed to the class at the beginning of the semester describes the course content and delivery, and defines the methods and criteria to be used in establishing the final grades for the course.
 

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.

  1. To describe major groups of cool season (northern temperate zone) turf diseases;
  2. To properly identify causal agents in turf disease samples using a diagnostic manual and a microscope;
  3. To recognize the effects of environmental conditions on turf diseases;
  4. To recognize the impact of turf disease management practices on the environment;
  5. To differentiate between biotic and abiotic disease symptoms; and
  6. To use cultural, biological and chemical techniques to minimize severity of turfgrass diseases.
