Abstract

Tolerance of sprigged ‘Tifsport’ and ‘Tifdwarf’ bermudagrass, ‘Meyer’ zoysiagrass, and ‘Salam’ seashore paspalum to oxadiazon (2,240 g/ha) or quinclorac (840 g/ha) applied 1 wk before sprigging (WBS), at sprigging (AS), 2 wk after sprigging (WAS), and 4 WAS was investigated in the field. Weed control was also evaluated. For both herbicides only the AS application timing injured the turfgrass greater than 22%, and injury for the other application timings ranged from 9 to 19% 5 WAS. When evaluated 8 WAS turfgrass injury following the AS application timing remained at 19%, and injury for all other timings was 8% or less. Eight WAS the 1 WBS, AS, 2 WAS, and 4 WAS application timings achieved 89, 79, 94, and 99% plot coverage, respectively, when averaged over all turfgrass species/cultivars and herbicides. By 13 WAS, all species/cultivars achieved at least 90% plot coverage. Presprigging applications of oxadiazon provided 98 to 100% goosegrass and old world diamond-flower control. Quinclorac applied AS provided greater than 70% control of these weeds. Results indicate that oxadiazon and quinclorac applied AS will cause unacceptable turfgrass injury. If goosegrass and/or old world diamond-flower are problematic, oxadiazon is a feasible choice for control of these weeds, but quinclorac is not.

Tolerancia de los zacates bermuda ‘Tifsport’ y de ‘Tifdwarf,’ ‘Meyer’ zoysiagrass y ‘Salam’ seashore paspalum a los herbicidas oxadiazon (2240 g/ha) o quinclorac (840 hg/ha) aplicados 1 semana antes del espigamiento (WBS), en el espigamiento(AS), 2 semanas después del espigamiento (WAS) y 4 WAS fueron investigados en el campo. El control de maleza fue también evaluado. Para ambos herbicidas solamente el tiempo de aplicación AS dañó el zacate en más del 22%, mientras que el daño para otros períodos de aplicación fue de un 9 a un 19% 5 semanas después de la siembra. Cuando se evaluó el daño en el zacate 8semanas después de la siembra siguiendo el tiempo de aplicación de AS éste permaneció en un 19% mientras que el daño pare cualquier otro tiempo de aplicación fue del 8% o menos. Los períodos de aplicación: 8WAS y 1WBS, AS, 2WAS y 4 WAS alcanzaron 89, 79, 94 y 99% de cobertura, respectivamente, cuando se promedian con todas las otras especies de zacate, cultivares y herbicidas. Para las 13 WAS, todas las especies cultivares alcanzaron al menos 90% de cobertura de la parcela. Las aplicaciones anteriores al espigamiento de oxadiazan proporcionaron de un 98 a un 100% en el control del zacate goose y del old world diamond flower. La aplicación de quinclorac al momento de la siembra proporcionó más del 70% de control de estas malezas. Los resultados indican que oxadiazon y quinclorac aplicados al momento de la siembra causarían daños inaceptables en el zacate. Si el zacate goose y el old world diamond flower son problemáticos, el oxadiazon es una opción factible para el control de estas malezas pero no así el quinclorac.
