Abstract

In the southeastern United States, Florida betony continues to be a problem weed in both turfgrass and ornamentals. Several herbicides including atrazine, dichlobenil, and glyphosate can provide good control (greater than 70%) of Florida betony, but their uses are limited. Over the past several years, many additional herbicides have been added to the turf market. New herbicides evaluated in this study included the sulfonylurea herbicides foramsulfuron, metsulfuron, and trifloxysulfuron; the picolinic acids clopyralid and fluroxypyr; and the aryl triazinone herbicide carfentrazone in combination with 2,4-D, dicamba, and mecoprop. In both the 2004 and 2005 trials, all sulfonylurea herbicides provided greater than 83% control of Florida betony at 10 wk after treatment. Other herbicides that provided less than 80% control of Florida betony in 2004 and 2005 included clopyralid, fluroxypyr, and the carfentrazone combination treatment. Selective control of Florida betony in ornamentals, however, still remains a challenge, as none of these herbicides are labeled for ornamentals.

En el sureste de los Estados Unidos, Stachys floridana (Florida betony) continúa siendo una maleza problemática tanto en las gramíneas como en las plantas ornamentales. Varios herbicidas, incluyendo atrazina, dichlobenil y el glifosato pueden proporcionar un buen control (mayor del 70%) al Stachys floridana, pero sus usos son limitados. En los últimos años, muchos herbicidas han sido introducidos al mercado. Algunos nuevos herbicidas fueron evaluados en este estudio incluyendo los herbicidas a base de sulfas: foramsulfuron, metsulfuron y trifloxysulfuron; los ácidos picolínicos: clopyralid y fluoroxipir y el herbicida aryl triazinone, en combinación con 2,4-D, dicamba y mecocrop. Tanto en los estudios realizados en 2004 como en 2005, todos los herbicidas lograron más del 83% de control de Stachys floridana, a las 10 semanas de su aplicación. Otros herbicidas que proporcionaron menos del 80% de control sobre Stachys floridana en 2004 y 2005 incluyeron una combinación de clopyralid, fluoroxipir y carfentrazone. Sin embargo, sigue siendo un reto lograr el control selectivo de Stachys floridana en las plantas ornamentales, ya que ninguno de estos herbicidas esta etiquetado para ese tipo de plantas.
