Abstract/Contents:"Bispyribac-sodium (BS) selectively controls annual bluegrass in cool-season turf but efficacy may be influenced by management practices, such as plant growth regulator (PGR) use. Experiments were conducted in New Jersey to investigate efficacy and absorption of BS applied with a PGR, trinexapac-ethyl (TE), for annual bluegrass control and creeping bentgrass tolerance. In laboratory experiments with annual bluegrass, creeping bentgrass, and perennial ryegrass, tank mixing TE with 14C-BS increased foliar absorption 43% from non-TE treated while absorption quadratically increased with TE rate. Differences in 14C-BS were not detected among emulsifiable concentration (EC), microencapsulated concentration (MC), and wettable powder (WP) TE formulations. In field experiments, two BS applications at 111 g ai/ha reduced annual bluegrass cover 93% from non-BS treated. TE applied before plus tank-mixed with BS averaged 67% greater annual bluegrass control than non-TE treated and reduced creeping bentgrass chlorosis up to 15% from BS alone. Tank mixing EC, MC, or WP TE formulations with BS provided similar annual bluegrass control and creeping bentgrass quality. Applications of BS reduced dollar spot (DS) cover 63% from non-BS treated over both years while TE reduced DS cover 50% from non-TE treated in 2005. Overall, regular TE use appears to have beneficial effects with BS for mitigating creeping bentgrass chlorosis, DS control, and improving efficacy for annual bluegrass by increasing foliar absorption."
