Turfgrass Herbicides: Mechanisms of Action and Resistance Management 1 Ramon G. Leon and Bryan Unruh 2 Target Audience The present document is a tool for turfgrass professionals, sod growers, landscape managers, and extension specialists to develop herbicide programs that reduce the risk of herbicide resistance (HR) evolution in turfgrass systems. This chart groups herbicides by their modes of action to assist you in selecting herbicides 1) to maintain greater diversity in herbicide use and 2) to rotate among herbicides with different sites of action to delay the development of herbicide resistance. DINOT-CondLightIta In order for this strategy to be effective, herbicides used in combination must belong to different sites of action AND be effective on the weed species. Herbicides should be a candidate cause when human sources and activities, site observations or observed effects support portions of the causal pathways (see Figure 2). For example, Herbicide Groups 2 and 9 are both Amino Acid Synthesis Inhibitors, which means their MOA is to shut down amino acids necessary for protein synthesis and ultimately plant growth.
