Weed suppression can be important during alfalfa establishment as weeds can reduce stand life, alfalfa biomass, and forage quality. To reduce these impacts producers commonly apply herbi-cides to establishing alfalfa. A range of options exist, but the most common applications include imazamox (Raptor) or imazethapyr (Pursuit). These compounds have traditionally given the best control of common weeds (e.g., lambsquarter & foxtail species) and can be applied post emer-gent. With the introduction of Roundup Ready® alfalfa, producers now have an additional choice for weed management.
