| Abstract/Contents: | "Field research was conducted from 2017 to 2019 in North Brunswick, NJ to evaluate the efficacy of Speedzone (2,4-D + mecoprop-p + dicamba + carfentrazone-ethyl at 860 + 270 + 80 + 28 g ha-1 , respectively) alone and tank-mixed with topramezone for post-emergence goosegrass (Eleusine indica) control. In 2017, treatments were initiated on 20 June to evaluate single and sequential Speedzone applications on a three or four wk interval. Fenoxaprop (140 g ha-1 ) and topramezone (25 g ha-1 ) applied twice four weeks apart were included as standards. In 2018, treatments were initiated on 11 July and consisted of single applications of Speedzone and Speedzone + topramezone (6 and 12 g ha-1 ), compared to two sequential applications of Speedzone on a 30-d interval. In 2019, treatments were initiated on 24 July and consisted of single applications of Speedzone EW (2,4-D + mecoprop-p + dicamba + carfentrazone-ethyl at 860 + 270 + 80 + 28 g ha-1 , respectively), topramezone at 12 g ha-1 , Speedzone EW + topramezone (12 g ha-1 ), and triclopyr (35 g ha-1 ) + topramezone (12 g ha-1 ). The site in 2017 was a fallow research field with a history of goosegrass. The site in 2018 and 2019 was a simulated golf course fairway consisting of perennial ryegrass (Lolium perenne) with a history of goosegrass. Goosegrass plants were at 3- to 5-tiller stage and cover was > 30% and when the experiments were initiated. Treatments were applied using a CO2-powered single nozzle boom with a 410 L ha-1 water carrier through an AI9504EVS nozzle. Topramezone was applied with MSO at 0.5% v/v, except when tank mixed with Speedzone. Goosegrass control was evaluated visually on a 0 (no control) to 100 (complete control) percent scale relative to a non-treated control. In 2019, goosegrass bleaching was evaluated visually on a 0 (no bleaching) to 100 (complete bleaching) percent scale relative to a non-treated control. In 2017, sequential applications of Speedzone provided >80% goosegrass control, while single applications provided <20% control at 9 WAIT. Sequential applications of fenoxaprop and topramezone provided >99% control. In 2018, tank mixtures of Speedzone + topramezone provided greater control (>85%) than Speedzone alone (45 to 55%) at 4 WAIT. Sequential applications of Speedzone provided more control than single applications of Speedzone from 5 to 12 WAIT. In 2019, tank mixtures of topramezone + Speedzone EW and topramezone + triclopyr displayed less bleaching than topramezone alone; Speedzone EW + topramezone displayed no bleaching while topramezone + triclopyr caused minor bleaching. Goosegrass control was generally similar among all treatments for the duration of the 2019 experiment. These data indicate sequential applications of Speedzone and Speedzone EW can control tiller-stage 107 goosegrass but single applications provide poor control. Tank mixing Speedzone with topramezone provided better goosegrass control than Speedzone alone and eliminated undesired bleaching caused by topramezone. Future research should investigate the efficacy of low Speedzone rates tank-mixed with topramezone for use in turfgrass species that are less tolerant of 2,4-D-based herbicide mixtures." |
