Cool-Season Turfgrass Diseases and Suppression Using Fungicides

This course introduces you to turfgrass diseases found on home lawns and sports fields and shows you how to suppress them using fungicides.

You will also look closely at environmental conditions, susceptible turfgrass species, and how fungicides suppress disease.

What you'll learn

At the end of this course you'll:

Be able to identify common turfgrass diseases.
Be able to understand how the environment affects disease expression.
Be able to understand how fungicides suppress turfgrass diseases.
Be able to develop a plan for mitigating turfgrass diseases.
Understand Integrated Pest Management and its role in reducing the risk of fungicide resistance.

Turfgrass Management Program

This course is part of the Turfgrass Management Program that includes the following component courses:

Please note: This course is primarily designed for those working in northern climates such as Oregon and Washington, Europe, Scandinavia and parts of Canada; however, course concepts may apply to other climate zones and some information on warm-season grasses is also covered. By focusing on these climates, you'll gain detailed information you can apply to your own park, field or lawn.
