Abstract

Methiozolin is a new herbicide from South Korea currently under development in the United States for PRE and POST annual bluegrass control in bentgrass and most other cool- and warm-season turfgrasses. Greenhouse studies were conducted in 2012 at the University of California, Riverside, CA, and Auburn University, Auburn, AL, to evaluate the relative tolerance of three bentgrass species comprised of nine creeping bentgrass (CRBG) cultivars, velvet bentgrass (VBG) and colonial bentgrass (COBG) to methiozolin at 0, 0.6, 1.1, 2.2, 4.5 and 9.0 kg ai ha−1. Methiozolin was applied 7 wk after seeding, followed by a second application 5 wk later. Methiozolin rates that produced 25% injury (TI25) and 50% clipping dry weight reduction (GR50) relative to a nontreated control for each species or cultivar were calculated using four-parameter logistic regression. Turf injury rates at 21 d after second treatment (DAT2) were the most consistent in describing relative tolerance among bentgrass species. Overall, CRBG was more tolerant to methiozolin than VBG or COBG. After two applications, methiozolin rates that caused TI25 were 1.1, 0.2, and 0.3 kg ha−1 for CRBG (across all cultivars), VBG, and COBG, respectively. VBG and COBG were not tolerant of sequential methiozolin applications at rates necessary to control annual bluegrass under field conditions. Herbicide rates that caused TI25 and GR50 decreased with the second application. ‘Penn A-4’ CRBG exhibited the highest TI25 28 d after initial treatment (DAIT) at University of California at Riverside (4.5 kg ha−1), but only 2.5 kg ha−1 with two applications by 21 DAT2. All CRBG cultivars tested tolerated methiozolin at 0.5 kg ha−1, the recommended sequential use rate for putting greens in Korea.

Methiozolin es un herbicida nuevo proveniente de Korea del Sur que está actualmente siendo desarrollado en los Estados Unidos para el control PRE y POST de Poa annua en Agrostis spp. (bentgrass) y la mayoría de otros céspedes de clima frío y cálido. Se realizaron estudios de invernadero en 2012 en la Universidad de California, Riverside, California y en la Universidad Auburn, Auburn, Alabama, para evaluar la tolerancia relativa de tres especies de Agrostis incluyendo nueve cultivares de Agrostis stolonifera (CRBG), Agrostis canina (VBG) y Agrostis capillaris (COBG) a methiozolin a 0, 0.6, 1.1, 2.2, 4.5, y 9.0 kg ai ha−1. Methiozolin fue aplicado 7 semanas después de la siembra, seguido por una segunda aplicación 5 semanas después. Las dosis de methiozolin que produjeron 25% de daño (TI25) y una reducción del 50% en el peso seco (GR50) de los residuos de poda (clippings) en relación al testigo no-tratado para cada especie o cultivar fueron calculados usando una regresión logística de cuatro parámetros. El daño en el césped según la dosis a 21 d después del segundo tratamiento (DAT2) fue el más consistente al describir la tolerancia relativa entre especies de Agrostis. En general, CRBG fue más tolerante a methiozolin que VBG o COBG. Después de dos aplicaciones, las dosis de methiozolin que causaron TI25 fueron 1.1, 0.2, y 0.3 kg ha−1 para CRBG (promediado para todos los cultivares), VBG, y COBG, respectivamente. VBG y COBG no fueron tolerantes a aplicaciones secuenciales de methiozolin a dosis que son necesarias para el control de Poa annua bajo condiciones de campo. Las dosis de herbicida que causaron TI25 y GR50 disminuyeron con la segunda aplicación. CRBG ‘Penn A-4’ mostró la mayor TI25 28 d después del tratamiento inicial (DAIT) en la Universidad de California en Riverside (4.5 kg ha−1), pero solamente 2.5 kg ha−1 con dos aplicaciones a 21 DAT2. Todos los cultivares de CRBG evaluados toleraron methiozolin a 0.5 kg ha−1, la cual es la dosis secuencial recomendada para el uso en putting greens en Korea.
