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 in Riverton, NJ investigated various regiments 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 greater in the spring compared to summer and fall. In the first experiment, Poa annua reductions were 22 and 30% in untreated turf and turf treated only with TE, respectively. Reductions in Poa annua were ≅55% for turf receiving PB with and without TE applications in the second experiment, PB reduced Poa annua populations to approximately half of the untreated plots but combinations with TE did not enhance turf quality of Poa annua suppression. Routinely applying PB at 0.14 kg ha-1 3 wk-1 provided similar Poa annua control to single applications of 0.56 kg ha-1 while both regimens gave better control than 0.28 kg ha-1 of PB applied in the spring and fall. Overall, PB wil be an effective tool for suppressing Poa annua in creeping bentgrass fairways for northeastern golf courses; however, tank mixing TE with PB will likely not enhance these effects."
