Abstract
Abstract Field experiments were conducted in 1988 and 1989 to evaluate various postemergence graminicides for common bermudagrass (Cynodon dactylon (L). Pers.) control in peanuts (Arachis hypogaea). A single application of fluazifop-P [(R)-2-[4[[5-(trifluorornethyl)-2-pyridinyl]oxy]phenoxy]propanoic acid] or clethodim [(E, E)-(±)-2-[1-[[(3-chloro-2-propenyl)oxy]imino] propyl]-5-[2-ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one] controlled approximately 25 to 30% more common bermudagrass than a single application of sethoxydim (2-[1-(ethoxyimino) butyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one) or quizalofop [(±)-2-[4[(6-chloro-2-quinoxalinyl)oxy]phenoxy]propanoic acid]. Two graminicide applications were required for greater than 90% common bermudagrass control. Treatments which provided greater than 90% control included two applications of sethoxydim (0.31 followed by (fb) 0.31 kg ha-1 or 0.31 fb 0.16 kg ha-1), fluazifop-P (0.21 fb 0.21 kg ha-1) or 0.21 fb 0.11 kg ha-1), and clethodim (0.28 fb 0.28 kg ha-1). These same treatments provided complete common bermudagrass control when evaluated the following summer. Peanut yield and net return from a single graminicide application generally were not improved with two applications.
