Abstract/Contents:"Sethoxydim {2- [1- (ethoxyimino) butyl] -5- [2-(ethylthio) propyl] -3-hydroxy-2-cyclohexen-1-one} at 0.34 kg ai/ha, fluazifop {(+/-) -2-[4-[[5-(trifluoromethyl)-2-pyridinyl] oxy] phenoxy] propanoic acid} at 0.13 kg ai/ha, and SC-1084 {3-hydroxy-4- [4- [[5-trifluoromethyl) -2-pyridinyl] oxy] phenoxy] pentanoic acid} at 0.28 kg ai/ha controlled 'Tifway' bermudagrass [Cynodon transvaalensis Burtt-Davy #3 CYNTR] x [Cynodon dactylon (L.) Pers. # CYNDA] nearly 100% when applied for 2 consecutive years. Tall fescue (Festuca arundinacea Schreb. 'Ky 31' # FESAR) tolerated fluazifop at 0.13 kg/ha and SC-1084 at 0.07 to 0.28 kg/ha; however, centipedegrass [Eremochloa ophiuroides (Munro) Hack. 'common' # ERLOP] and zoysiagrass (Zoysia japonica Steud. #ZOYJA x Zoysia tenuifolia Willd. ex trin. 'Emerald' # ZOYTE) did not tolerate these treatments. Centipedegrass tolerated sethoxydim, zoysiagrass tolerance was intermediate, and tall fescue was injured severely. Sethoxydim at 0.22 kg/ha discolored leaves of zoysiagrass, but the turf recovered fully. Thus, bermudagrass, when mixed with either tall fescue, centipedegrass, or zoysiagrass, can be controlled selectively with herbicides applied postemergence."
