Abstract
Field studies were conducted from 2007 through 2009 to determine weed efficacy and peanut ( Arachis hypogaea L.) response to herbicide systems that included ethalfluralin applied preplant incorporated. Control of devil's claw ( Proboscidea louisianica (Mill.) Thellung), yellow nutsedge ( Cyperus esculentus L.), Palmer amaranth ( Amaranthus palmeri S. Wats.), and puncturevine ( Tribulus terrestris L.) was most consistent with ethalfluralin followed by either imazapic or imazethapyr applied postemergence. Peanut stunting was 19% when paraquat alone was applied early-postemergence. Stunting increased to greater than 30% when ethalfluralin applied preplant incorporated was followed by S -metolachlor applied preemergence and paraquat applied early-postemergence. Stunting (7%) was also observed when ethalfluralin was followed by flumioxazin plus S -metolachlor applied preemergence with lactofen applied mid-postemergence. Ethalfluralin followed by paraquat applied early-postemergence reduced peanut yield when compared to the nontreated check. Ethalfluralin applied preplant incorporated followed by imazapic applied mid-postemergence provided the greatest yield (6220 kg/ha). None of the herbicide treatments reduced peanut grade (sound mature kernels plus sound splits) when compared with the nontreated check.

8 of 14 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.
Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
