Field studies conducted in 1992 at Tifton and Midville, GA and in 1993 at Attapulgus, GA evaluated imazethapyr systems for weed control, peanut (Arachis hypogaea L.) injury, and yield. The standard of imazethapyr + paraquat early postemergence (EPOST) followed by paraquat + 2,4-DB + bentazon postemergence (POST) controlled at least 87% of bristly starbur, prickly sida, smallflower morningglory, and yellow nutsedge and the peanut crop yielded 3310 kg/ha. This standard controlled Florida beggarweed (46 and 83% control) and sicklepod (74 and 88% control) in 1992 and 1993; respectively. Imazethapyr PPI at 36 and 72 g/ha controlled bristly starbur 78 and 100%, respectively, and controlled prickly sida and smallflower morningglory at least 90%. Imazethapyr PPI at 36 and 72 g/ha controlled yellow nutsedge 83 and 80%, respectively. Imazethapyr did not control sicklepod or Florida beggarweed. Control of these two species and high peanut yields required a POST application of a paraquat mixture.
