This document provides information on fungicides for turfgrass disease control, including their mode of action, chemical class, common names, trade names, and resistance risk level. It lists 27 fungicide classes and over 50 active ingredients that are commonly used to control diseases in turfgrass. Many active ingredients have a moderate to high risk of developing fungal resistance with repeated use.
