This notice describes purely voluntary pesticide resistance management labeling guidelines based on mode/target site of action for agricultural uses of herbicides, fungicides, bactericides, insecticides, and acaricides. This document provides acceptable schemes of classification of pesticides according to their mode/target site of action (Appendices I-III), a standard format for showing group identification symbols on the end-use product labels, and examples of resistance management labeling in the use directions. These guidelines are the result of a joint effort of the U.S. and Canada under the North American Free Trade Agreement (NAFTA).
