Abstract:
... Florpyrauxifen-benzyl is a new herbicide being developed for rice. Research is needed to understand its spectrum of control and optimal tank-mix partners. Multiple greenhouse and field experiments were conducted to evaluate florpyrauxifen-benzyl efficacy and tank-mix compatibility. In greenhouse experiments, florpyrauxifen-benzyl at 30 g ai ha⁻¹ provided ≥75% control of all weed species evaluated ...

Abstract:
... Field studies were conducted from 2006 to 2008 in the peanut (Arachis hypogaea) growing regions of Georgia, North Carolina, and Texas to ascertain two formulations of imazapic marketed as formulation-1 (Cadre®) and formulation-2 (Impose®). Both formulations controlled Acanthospermum hispidum, Eclipta prostrate, Richardia scabra, Verbesina encelioides, Amaranthus palmeri, Ipomoea lacunosa, Sida s ...

Abstract:
... A field experiment was conducted during three cropping seasons to compare weed control and cotton yield provided by conventional (CV), glufosinate-resistant (LL), and glyphosate-resistant (RR) weed management systems under standard (102 cm) and narrow (38 cm) row spacing grown in conventional and conservation tillage systems. The conventional tillage and/or CV cotton received a PRE application of ...

Abstract:
... Field experiments were conducted at several Texas peanut growing regions during the 1999 and 2000 growing seasons to study weed control and peanut response to sulfentrazone. Sulfentrazone applied preplant incorporated (PPI) or preemergence (PRE) caused up to 80% peanut stunt when rated 4-5 weeks after planting (WAP). The severity of stunting increased as sulfentrazone dose increased. Panicum texan ...

Abstract:
... A greenhouse experiment was conducted to evaluate the herbicidal activity of five aliphatic (ethyl, propyl, butyl, allyl, and 3-methylthiopropyl) and three aromatic (phenyl, benzyl, and 2-phenylethyl) isothiocyanates (ITCs) on Palmer amaranth, pitted morningglory, and yellow nutsedge. All ITCs were applied to soil at 0, 10, 100, 1,000, and 10,000 nmol g⁻⁻¹ of soil and incorporated. All ITCs had a ...

Abstract:
... An experiment conducted at five locations in North Carolina during 1998 and 1999 evaluated weed management systems in cotton with CGA-362622 and pyrithiobac. Weed management systems evaluated different combinations with or without fluometuron preemergence (PRE) followed by (fb) CGA-362622 early postemergence (EPOST), postemergence (POST), or EPOST ++ POST; or pyrithiobac EPOST fb prometryn plus MS ...
