“Effects of selected herbicides on sod tensile strength and rooting of mature and immature turf of common centipedegrass [Eremochloa ophiuroides (Munro.) Hack] were studied in field experiments. Herbicides evaluated were atrazine, atrazine + tridiphane, bensulide, DCPA, DPX-6316, imazapyr, imazaquin, napropamide, oxadiazon, pendimethalin, sethoxydim, simazine, and sulfometuron. At 2, 4, and 8 weeks after treatment (WAT), sod tensile strength was determined, and root length and number were measured 7 to 10 days later. In 1986 sod tensile strength was not affected, but in 1987 the tensile strength of the immature turf was reduced at 8 WAT by bensulide and imazapyr. Rooting was suppressed most by benstdide, imazapyr, napropamide, and sulfometuron at most rates and dates tested. By 8 WAT, root length, root number, and tensile strength of herbicide-treated centipedegrass sod did not differ from that of the untreated sod except for those plots treated with bensulide or imazapyr.
