Abstract/Contents:"Preemergence herbicides may negatively affect hybrid bermudagrass establishment. However, little is known about the effects upon root architecture and development. Research was conducted to evaluate the effects of atrazine (1.12 kg ha-1), atrazine (1.12 kg ha-1) + S-metolachlor (0.86 kg ha-1), dithiopyr (0.56 kg ha-1), flumioxazin (0.286 kg ha-1), indaziflam (0.033 kg ha-1), liquid and granular applied oxadiazon (2.24 kg ha-1), S-metolachlor (2.78 kg ha-1), pendimethalin (1.66 kg ha-1), prodiamine (0.594 kg ha-1), and simazine (2.24 kg ha-1) on Latitude 36 hybrid bermudagrass growth. Other than atrazine (31 to 40 d) and granular applied oxadiazon (23 to 29 d), treatments increased days required to reach 50% cover (24 to 33 d). All herbicide treatments reduced root mass when harvested 6 WAT relative to the nontreated. By 10 WAT, all treatments reduced root mass in run 1, but during run 2, only prodiamine (0.293 kg m-3), pendimethalin (0.334 kg m-3), simazine (0.405 kg m-3), atrazine + S-metolachlor (0.394 kg m-3), liquid applied oxadiazon (0.379 kg m-3), and indaziflam (0.154 kg m-3) reduced dry root mass compared to the nontreated (0.861 kg m-3). At 4 WAT, all treatments other than simazine (7.0 mm cm-3) and granular applied oxadiazon (11.1 mm cm-3) reduced root length when compared to the nontreated (10.4 mm cm-3). By 10 WAT, only dithiopyr (14.7 mm cm-3), S-metolachlor alone (14.9 mm cm-3), and indaziflam (9.9 mm cm-3) reduced root length when compared to the nontreated (22.1 mm cm-3). No differences were detected in the total amount of nonstructural carbohydrates within the roots in either run of the experiment. Results suggest that hybrid bermudagrass roots were able to grow out of the initial herbicidal injury for every treatment other than indaziflam by 10 WAT; however, future research should evaluate tensile strength of treated sod."
