| Abstract/Contents: | "St. Augustinegrass [Stenotaphrum secundatum (Walt.) Kuntze] sod production involves stolon regeneration from strips left from the previous harvest. Field studies were conducted to evaluate stolon regrowth and rooting following preemergence application of herbicides. Herbicides evaluated were atrazine [6-chloro-N-ethyl-N'-(1-methylethyl)-1,3, 5 triazine-2,4-diamine], dithiopyr [S, S-dimethyl 2- (difluoromethyl) -4-(2-methylpropyl) -6- (trifluormethyl) -3,5-pyridinecarbothioate], isoxaben [N-[3- (1-ethyl-1-methylpropyl) -5-isoxazolyl] -2,6-dimethoxy benzamide], metolachlor [2-chloro-N- (2-ethyl-6-methylphenyl) -N- (2-methoxy-1-methylethyl) acetamide], oxadiazon [3-[2,4-dichloro-5- (1-methylethoxy) phenyl]-5- (1, 1-dimethylethyl) -1,3,4-oxadiazol-2-(3H)-one], pendimethalin [N-(1-ethylpropyl) -3,4-dimethyl-2,6-dinitrobenzenamine] and the combination of metolachlor plus atrazine. Acceptable 'Floratam' St. Augustingegrass color was noted following all treatments. Twelve to 24% of the stolons were unrooted 4 to 8 mo after application following treatment with 0.8 kg a.i. ha-1 dithiopyr. Five to 22% of the stolons were unrooted 8 mo after treatment with isoxaben at 1.1 kg ha-1 and pendimethalin at 2.2 kg ha-1. Data collected after 8 mo showed stolon rooting to be similar to the untreated for all treatments. Turfgrass density was unaffected or slightly improved (approximately 25%) by herbicide treatment and was highest with oxadiazon, metolachlor, and letolachlor plus atrazine treatments. Neither turfgrass tensile strength nor root dry weight was reduced 14 mo after treatment with any of the herbicides evaluated. Although short-term (2 to 4 mo) negative effects followed dithiopyr, isoxaben, and pendimethalin treatments, long-term (>=8 mo) effects were transient." |
