Abstract

Field studies were conducted in wild blueberry in 2007 and 2008 to evaluate the efficacy of hexazinone applied PRE and multiple application timings of POST mesotrione on goldenrods and the efficacy of burning, terbacil applied PRE, nicosulfuron/rimsulfuron applied POST, and multiple application timings of mesotrione applied POST on black bulrush. Mesotrione application timings were at 10 and 30 cm of height, floral bud initiation, and full flower. Hexazinone applied at 1.92 kg ha−1 in 200 L water ha−1 effectively suppressed goldenrods. At least 90% goldenrod damage was achieved with mesotrione POST applied at 101 g ha−1 in 300 L water ha−1 before full flower, following hexazinone PRE at two of three sites. Damage following mesotrione was more variable when hexazinone was not applied. Mesotrione efficacy was lower when applied in the crop year, but a crop-year registration may be warranted to improve harvest ease and increase berry quality. A single application of mesotrione at the label rate did not adequately control black bulrush. Ninety percent black bulrush control was achieved with rimsulfuron/nicosulfuron applied at a rate of 0.03 g L−1 of water with 0.2% v/v nonionic surfactant. Equivalent levels of control were achieved with sequential mesotrione applications at the label rate.

Estudios de campo se realizaron en cultivos de la mora azul silvestre en los años 2007 y 2008 para evaluar la eficacia de hexazinone PRE aplicado y de los tiempos de aplicación múltiple de mesotrione POST-aplicado en Solidago spp. También se estudiaron los impactos de la quema de terbacil PRE aplicado, de nicosulfuron/rimsulfuron POST aplicado y los tiempos de aplicación múltiple de mesotrione POST aplicado al Scirpus atrovirens Willd. Los tiempos de aplicación de mesotrione fueron a los 10 y 30 cm de altura, a la iniciación floral y a la floración plena. El hexazinone aplicado a 1.92 kg ha−1 en 200 Lts de agua suprimió efectivamente la Solidago spp. Al menos el 90% del daño a esta maleza fue atribuido al mesotrione POST aplicado a 101 g ha−1 en 300 Lts de agua antes de la floración plena, seguido del hexazinone aplicado en dos de los tres sitios. El daño causado por el mesotrione fue más variable cuando no se aplicó el hexazinone. El uso del mesotrione se justificó para facilitar la cosecha y mejorar la calidad del fruto. Una sola aplicación de mesotrione a la dosis indicada en la etiqueta no controló adecuadamente la Scirpus atrovirens Willd. El 90% del control de dicha maleza se logró con la aplicación de rimsulfuron/nicosulfuron aplicados a una dosis de 0.03 g Lt−1 de agua con 0.2% v/v de surfactante no iónico. Niveles equivalentes de control se alcanzaron con aplicaciones secuenciales de mesotrione a la dosis indicada en la etiqueta.
