The Effect of Three Postemergence Grass Herbicides on Quackgrass (Agropyron Repens (L.) Beauv.) and Selected Ornamental Shrubs, Ground Covers, and Bedding Plants (fluazifop-P-Butyl, Sethoxydim, Quizalofop-Ethyl, Dpx-Y6202)

Applications of 0.28 kg ai/ha fluazifop-p-butyl + Surfactant WK 0.25% (by. vol), 0.56 kg ai/ha sethoxydim + crop oil concentrate 1%, and 0.56 kg ai/ha DPX-Y6202 + Surfactant WK 0.25% to Agropyron repens shoots interfered with cyto- and karyokinesis of the rapidly expanding leaves within two days after treatment (DAT). A. repens plants treated with these herbicides also developed visual injury symptoms within three days after treatment and, compared to the check, had a significant reduction in dry weight within 12 DAT.
