Field studies were conducted in south Texas in 1994 and 1995 to evaluate various soil-applied herbicides alone and in combination with postemergence herbicides for golden crownbeard control. Ethalfluralin preplant incorporated (PPI) followed by imazapic or lactofen postemergence (POST) provided 100% golden crownbeard control. Ethalfluralin PPI followed by oxyfluorfen applied preemergence (PRE) or metolachlor + imazethapyr provided 90% control. Dimethenamid, ethalfluralin, and metolachlor alone failed to adequately control golden crownbeard. Golden crownbeard control was most effective when combination treatments were used (PPI or PRE followed by POST). Effective golden crownbeard control increased peanut yields up to 53% over that of the untreated check.
