Clethodim, cycloxydim, haloxyfop, fluazifop-P, fenoxaprop, and quizalofop were applied early or late postemergence to Texas panicum (Panicum texanum Buckl.) and southern crabgrass (Digitaria ciliaris (Retz.) Koel.) in peanuts (Arachis hypogaea L.). Clethodim at 0.11 and 0.14 kg/ha, cycloxydim at 0.11 and 0.17, and fluazifop-P at 0.17 and 0.21 kg/ha provided excellent Texas panicum control. Fluazifop-P provided erratic southern crabgrass control, while clethodim, cycloxydim, haloxyfop, fenoxaprop at 0.22 kg/ha, and quizalofop at 0.14 kg/ha provided excellent southern crabgrass control. Yields of peanuts were usually higher following early postemergence application, thus indicating the timing of application is important in improving yields.
