Abstract

Synthetic auxin herbicides are widely used because of their effective control of broadleaf weeds and safety in many turfgrass species. However, two synthetic auxin herbicides, triclopyr and aminocyclopyrachlor (AMCP; DPX-KJM44), are known to injure warm-season turfgrasses. Our objective was to quantify this injury through evaluations of turfgrass quality and turfgrass green cover in response to herbicide treatment. The results of this study indicate that relative to the labeled use rates of triclopyr (0.56 to 1.12 kg ae ha−1) and AMCP (0.053 kg ai ha−1), zoysiagrass is the only turfgrass tested with sufficient tolerance to the respective compounds for their use as weed-control agents. Bermudagrass and centipedegrass may be injured by triclopyr and AMCP at labeled rates, characterized by a reduction in turfgrass quality and green cover. St. Augustinegrass is not tolerant of either triclopyr or AMCP at labeled rates.

Las auxinas sintéticas son herbicidas ampliamente usados debido a su control efectivo en malezas de hoja ancha y por ser seguros para muchas especies de césped. Sin embargo, dos de ellos, triclopyr y aminocyclopyrachlor (AMCP, DPX-KJM44), son conocidos por dañar céspedes de clima cálido. Nuestro objetivo fue cuantificar este daño a través de evaluaciones de la calidad y cobertura verde de los céspedes en respuesta al tratamiento del herbicida. Los resultados de este estudio indican que, relativamente a las dosis recomendada de triclopyr (0.56 a 1.12 kg ea ha−1) y AMCP (0.053 kg ia ha−1), Zoysia japonica fue el único césped estudiado con suficiente tolerancia a los herbicidas usados para el control de maleza. Cynodon dactilon y Eremochloa ophiuroides podrían ser dañados por triclopyr y AMCP a las dosis recomendadas, caracterizados por una reducción en la calidad y cobertura verde el césped. Stenotaphrum secundatum no es tolerante a triclopyr ni a AMCP a las dosis recomendadas.
