About Turf FRAC Tracker

This program was designed for turf grass practitioners to help make fungicide resistance management easier. Recommendations from the program are based on one important principle: avoiding consecutive or repeated use of fungicides with the same single site mode of action will prevent the development of fungicide resistance in populations of the targeted fungal pathogen.

The Fungicide Resistance Action Committee (FRAC) classifies fungicides by their mode of action, assigning each mode of action a different FRAC number. This program allows turf grass managers to quickly identify whether they are applying fungicides of the same FRAC number. Fungicide rotation between FRAC numbers will reduce the risk of resistance development.

Fungicides are given an efficacy rating based on relative effectiveness to allow the user of this program to select products that have been trialed and proven effective against the pathogens they wish to control. This efficacy rating is updated yearly from "Chemical Control of Turfgrass Diseases" written by Paul Vincelli and David Williams of the University of Kentucky Cooperative Extension Service.

Disclaimer

The University of Massachusetts does not endorse the commercial fungicides listed in this program. Other fungicides for use on turf that are not listed here should be brought to our attention in order to add these products to future versions of this program. Fungicide applicators are responsible for following licensing regulations and product labels in their respective states. Be sure to read and follow safety precautions and current label information before making any fungicide application.
