This guide is one that all turfgrass managers should have on their desk or in digital format: Identification & Management of Turfgrass Diseases. And it doesn't cost anything. It is a free download, as a 56 page full color PDF file.

Written by Barb Corwin, Ned Tisserat, and Brad Fresenburg, and published by the University of Missouri Extension, this guide begins with an overview of disease ID and control and proceeds to a 2-page section on each of the major turfgrass diseases.

I've found this guide especially useful, along with the Chemical Control of Turfgrass Diseases (also free!) by Vincelli and Munshaw.

If you want to see which turfgrass species are hosts to which diseases, or which fungicides can control which diseases, you will find that information in the opening pages.

Then comes a step-by-step guide to identifying diseases. After that are the 2-page summaries of each disease, covering Symptoms and Signs, Conditions under which the disease can occur, and Management.
