Abstract
In field studies, a preemergence application of metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl)acetamide] followed by an early postemergence application of dicamba (3,6-dichloro-o-anisic acid) gave good season-long control of smooth pigweed (Amaranthus hybridusL. ♯ AMACH) in conventional and no-till corn (Zea maysL. ‘Pioneer 3184’ and ‘Pioneer 3382’). In soybeans [Glycine max(L.) Merr. ‘Williams' and ‘Essex’], best control of smooth pigweed was achieved with an early postemergence application of sethoxydim {2-[1-(ethyoxy-imino)butyl]-5-[2-(ethylthio) propyl]-3-hydroxy-2-cyclohexen-1-one} plus acifluorfen {5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid}. Tillage played a role in the degree of smooth pigweed control. Best control of smooth pigweed in corn was obtained when the ground was moldboard plowed and disced, and least control was obtained when corn was no-till planted in the previous year's corn stalks or in a rye (Secale cerealeL.) cover crop.
