Abstract

Fenoxaprop effectively controls crabgrass in tall fescue turf, but antagonism with growth-regulating herbicides reduces potential to apply fenoxaprop in combination with many herbicides registered for broadleaf weed control. Aminocyclopyrachlor is a new broadleaf weed control herbicide that has not been evaluated in combination with fenoxaprop. Field experiments were conducted in Georgia, New Jersey, and Tennessee to investigate tank mixtures of fenoxaprop with aminocyclopyrachlor for smooth crabgrass and white clover control. Fenoxaprop alone exhibited substantial activity on smooth crabgrass but control was greater with fenoxaprop + aminocyclopyrachlor treatments. By 4 and 6 wk after treatment (WAT), approximately 22 and 44% less fenoxaprop was required to achieve 80% smooth crabgrass control when the herbicide was tank-mixed with aminocyclopyrachlor at 52.5 and 79 g ai ha−1, respectively. Fenoxaprop did not reduce white clover control with aminocyclopyrachlor because 97% control was achieved by 4 WAT for all aminocyclopyrachlor + fenoxaprop treatments. Tall fescue was not injured by any treatment. Results suggest aminocyclopyrachlor enhances fenoxaprop efficacy for smooth crabgrass control in tall fescue.

El fenoxaprop controla efectivamente Digitaria spp. en Festuca arundinacea pero su antagonismo con herbicidas reguladores de crecimiento reduce el potencial para aplicar fenoxaprop en combinación con muchos de los herbicidas registrados para el control de malezas de hoja ancha. Aminocyclopyrachlor es un nuevo herbicida controlador de malezas de hoja ancha que aún no ha sido evaluado en combinación con fenoxaprop. Se realizaron experimentos de campo en Georgia, New Jersey y Tennessee para evaluar la mezcla en tanque de fenoxaprop con aminocyclopyrachlor para el control de D. ischaemum y Trifolium repens. El fenoxaprop aplicado solo mostró actividad sustancial en D. ischaemum, pero el control fue mayor con los tratamientos de fenoxaprop + aminocyclopyrachlor. Para las semanas 4 y 6 después del tratamiento (WAT), aproximadamente se requirió 22 y 44% menos fenoxaprop para obtener un control del 80% de D. ischaemum cuando el herbicida se mezcló en tanque con aminocyclopyrachlor a 52.5 y 79 g ia ha−1, respectivamente. El fenoxaprop no redujo el control de T.repens causado por el aminocyclopyrachlor, pues el 97% de control se logró a las 4 WAT con todos los tratamientos de aminocyclopyrachlor + fenoxaprop. F. arundinacea no sufrió daños con ninguno de los tratamientos. Los resultados sugieren que aminocyclopyrachlor aumenta la eficacia de fenoxaprop para el control de D.ischaemum en el cultivo de F. arundinacea.
