Abstract

Field experiments were conducted in Auburn, AL in 2008 and 2009 to assess new aryloxyphenoxypropionate (AOPP) herbicides applied alone and tank-mixed with triclopyr for Tifway bermudagrass control in Zorro zoysiagrass. Treatments included three sequential applications of clodinafop (0.07 kg ai ha−1); triclopyr (1.12 kg ae ha−1); clodinafop + triclopyr (0.07 + 1.12 kg ha−1); fenoxaprop (0.10 kg ai ha−1); fenoxaprop + triclopyr (0.10 + 1.12 kg ha−1); metamifop (0.40 kg ai ha−1); and metamifop + triclopyr (0.40 + 1.12 kg ha−1). Clodinafop, fenoxaprop, and metamifop applied alone controlled Tifway bermudagrass 32 to 65% when rated 3 wk after the final application; however, the addition of triclopyr to these AOPP herbicides increased bermudagrass control to ≥ 89%. All AOPP herbicides applied alone caused unacceptable injury to Zorro zoysiagrass (20 to 42%) 3 wk after the final application. Clodinafop resulted in the greatest zoysiagrass injury (42%), whereas metamifop caused moderate injury (20%). Zorro zoysiagrass exhibited less injury (< 3%) and greater turf coverage (≥ 95%) when AOPP herbicides were tank-mixed with triclopyr. Of the three AOPP herbicides evaluated in this study, only fenoxaprop is currently labeled for use on turfgrass. However, the nonlabeled herbicides (clodinafop and metamifop) provided bermudagrass control and zoysiagrass safety equal to the commercial standard (fenoxaprop) 3 wk after the final application when tank-mixed with triclopyr. Where zoysiagrass is contaminated with bermudagrass, turf managers will likely have to make applications of AOPP herbicides tank-mixed with triclopyr over multiple years to control bermudagrass as it will continue to regrow from deep rhizomes.

Se llevaron al cabo experimentos de campo en Auburn, AL en 2008 y 2009 para evaluar nuevos herbicidas ariloxifenoxi-propionato (AOPP) aplicados por sí solos o mezclados con triclopyr para el control del zacate bermuda var. “Tifway” en el cultivo de zacate zoysia var. “Zorro”. Los tratamientos incluyeron tres aplicaciones secuenciales de clodinafop (0.07 kg ia ha−1); triclopyr (1.12 kg ea ha−1); clodinafop + triclopyr (0.07 + 1.12 kg ha−1); fenoxaprop (0.10 kg ia ha−1); fenoxaprop + triclopyr (0.10 + 1.12 kg ha−1); metamifop (0.40 kg ia ha−1); y metamifop + triclopyr (0.40 + 1.12 kg ha−1). El clodinafop, fenoxaprop, y metamifop aplicados por sí solos controlaron el bermuda “Tifway” de 32 a 65% cuando se evaluó 3 semanas después de la última aplicación; sin embargo, la adición de triclopyr a estos herbicidas AOPP incrementaron el control de bermuda “Tifway” ≥89%. Todos los herbicidas AOPP aplicados individualmente causaron daño inaceptable al zacate zoysia var. “Zorro” (20 a 42%), 3 semanas después de la última aplicación. El clodinafop causó el mayor daño al zacate zoysia (42%), mientras que el metamifop causó daño moderado (20%). El zacate zoysia var. “Zorro” exhibió menos daño (<3%) y una mejor cobertura de césped (≥95%), cuando los herbicidas AOPP se mezclaron en tanque con triclopyr. De los tres herbicidas AOPP evaluados en este estudio, solamente fenoxaprop está actualmente etiquetado para su uso en césped. Sin embargo, los herbicidas no etiquetados (clodinafop and metamifop), proporcionaron control en bermuda y seguridad en el zacate zoysia igual al estándar comercial (fenoxaprop), tres semanas después de la última aplicación, cuando se mezcló en tanque con triclopyr. En situaciones en que el zacate zoysia está contaminado con zacate bermuda, los responsables del cuidado del césped probablemente tendrán que aplicar herbicidas AOPP mezclados en tanque con triclopyr por varios años, para controlar el zacate bermuda conforme rebrote de sus rizomas profundos.
