Abstract

Research was conducted in 2003 and 2004 to evaluate diflufenzopyr tank mixes for western ragweed control and injury to ‘Tifton 85′ bermudagrass. In 2003 at 94 DAT, picloram at 0.28 and 0.56 kg ae ha−1 with or without diflufenzopyr provided greater than 95% control of western ragweed, whereas triclopyr + dilfufenzopyr, dicamba + diflufenzopyr, triclopyr alone, and diflufenzopyr alone provided < 77% control. In 2004 at 95 DAT, only the highest rate of picloram alone provided 96% control, and the two highest rates of picloram + diflufenzopyr provided at least 95% control. Tifton 85 bermudagrass growth reduction increased with the addition of diflufenzopyr to picloram in 2003, but not in 2004. However, forage dry-matter yield was not reduced by any herbicide treatment compared to the nontreated control. Results of these studies indicate that picloram alone and picloram + diflufenzopyr provide excellent control of western ragweed. The tank mixture of picloram + diflufenzopyr can improve control over picloram alone. However, dicamba + diflufenzopyr, triclopyr + diflufenzopyr, triclopyr alone, and diflufenzopyr alone did not provide adequate control.

En 2003 y 2004 se realizó una investigación para evaluar mezclas en tanque con diflufenzopyr para el control de Ambrosia psilostachya y el daño en Cynodon dactylon ‘Tifton 85′. En 2003 a 94 DAT, picloram a 0.28 y 0.56 kg ae ha−1 con o sin diflufenzopyr brindó un control superior a 95% de A. psilostachya, mientras que triclopyr + diflufenzopyr, dicamba + diflufenzopyr, triclopyr solo, y diflufenzopyr solo, brindaron control <77%. En 2004 a 95 DAT, solamente la dosis más alta de diflufenzopyr solo brindó 96% de control, y las dos dosis más altas de picloram + diflufenzopyr brindaron al menos 95% de control. La reducción en el crecimiento de C. dactylon ‘Tifton 85′ aumentó con la adición de diflufenzopyr a picloram en 2003, pero no en 2004. Sin embargo, el rendimiento en materia seca del forraje no se redujo con ninguno de los tratamientos de herbicidas al compararse estos con el testigo no-tratado. Los resultados de estos estudios indican que picloram solo y picloram + diflufenzopyr brindan un control excelente de A. psilostachya. La mezcla en tanque de picloram + diflufenzopyr puede mejorar el control en comparación con picloram solo. Sin embargo, dicamba + diflufenzopyr, triclopyr + diflufenzopyr, triclopyr solo, y diflufenzopyr solo no brindaron un control adecuado.
