| Abstract/Contents: | "Plant growth regulators (PGRs) are commonly applied for Poa annua suppression but various PGR regimens may be more applicable in creeping bentgrass management than exclusive applications. Two field experiments were conducted from 2001 to 2004 in Riverton, NJ to investigate various regimens of paclobutrazol (PB) and trinexapac-ethyl (TE) for Poa annua control in creeping bentgrass golf course fairways. Over the four years, Poa annua coverage was 36% greater in the spring compared to summer and fall. In the first experiment, Poa annua coverage was 25 to 39% less in bentgrass treated with PGR regimens than untreated turf. Turf treated with regimens including PB had 19% less Poa annua coverage than exclusive TE treatments. In the second experiment, Poa annua coverage was reduced 20 to 37% when PB was included in the PGR regimen and overall population reductions were 80 to 120% greater than untreated turf. Applying PB at 0.14 kg ai ha-1 3wk-1 from spring to fall suppressed Poa annua populations similarly to applications at higher rates applied only in the spring or fall. Exclusive TE applications had best turf quality results but inconsistent Poa annua control over the two experiments. However, routinely applying TE with periodic PB applications controlled Poa annua similarly to PB applied exclusively. Turf receiving PB with and without TE had similar or reduced turf quality than the untreated but quality was always acceptable. Regimens with both PGRs may be advantageous for Poa annua management and bentgrass growth suppression." |
