Abstract

Amicarbazone has potential for selective annual bluegrass control in cool-season turfgrasses, but seasonal application timings may influence efficacy. To test this hypothesis, field experiments in New Jersey and Indiana investigated amicarbazone efficacy from fall or spring applications and growth chamber experiments investigated the influence of temperature on efficacy. Fall treatments were more injurious to creeping bentgrass and Kentucky bluegrass than spring applications, but fall applications were also more efficacious for annual bluegrass control. In growth chamber experiments, injury and clipping weight reductions were exacerbated by increased temperatures from 10 to 30 C on annual bluegrass, creeping bentgrass, Kentucky bluegrass, and perennial ryegrass. Results suggest that amicarbazone use for annual bluegrass control in cool-season turf may be limited to spring applications, but increased temperature enhances activity on all grasses.

El Amicarbazone tiene potencial para el control selectivo de la Poa annua L. en céspedes establecidos en la estación templada, pero los tiempos de aplicación estacional podrían influenciar su eficacia. Para probar esta hipótesis, se realizaron experimentos de campo en New Jersey e Indiana en los cuales se investigó la eficacia del amicarbazone en aplicaciones de otoño o primavera y se realizaron experimentos en cámaras de crecimiento controlado en que se midió la influencia de la temperatura sobre la eficacia. Los tratamientos en el otoño fueron más dañinos para la Agrostis stolonifera L., y la Poa pratensis L., comparados con las aplicaciones de primavera, pero las aplicaciones de otoño fueron también más eficaces para el control de la Poa pratensis L. En los experimentos en cámara de crecimiento controlado, el daño y la reducción en el peso del material cortado se intensificaron en respuesta al incremento en la temperatura de 10 a 30 C en la Poa annua L, la Agrostis stolonifera L, la Poa pratensis L y la Lolium perenne L. Los resultados sugieren que el uso de amicarbazone para el control de la Poa annua L en céspedes establecidos en la temporada templada, podría limitarse a aplicaciones de primavera, pero el incremento en la temperatura resulta en una mayor actividad en todos los pastos.
