Chemical Weed Control in New Spring-Seeded Alfalfa

Weed management is one of the most important practices in alfalfa production, particularly in new seeding. This bulletin briefly discusses two chemical-based approaches: preemergence or preplant incorporated and early postemergence. A handy table reports the effectiveness of herbicides on five different weeds so that you can better protect your first harvest and a less stressful growing season. Color photographs provide the in-field results.
