Field studies were conducted in 1994 and 1995 to evaluate CGA-152005 for weed control and effect on peanut (Arachis hypogaea) yield in Texas peanut production areas. CGA-152005 at 10 to 20 g/ha controlled eclipta (Eclipta prostrata), golden crownbeard (Verbesina enceliodes), and Palmer amaranth (Amaranthus palmeri) > 90% when applied preemergence (PRE) or soon after peanut emergence (EPOST). CGA-152005 postemergence (POST) controlled eclipta > 95%; sandhills amaranth (Amaranthus arenicola) 99%; golden crownbeard, pitted morningglory (Ipomoea lacunosa), and hophornbeam copperleaf (Acalypha ostryifolia) < 80%; and Palmer amaranth and ivyleaf morningglory (Ipomoea hederacea) from 37 to 89%. CGA-152005 injured peanut up to 37% and reduced yield up to 94%.
