Abstract

Field studies were conducted near Crowley, LA, in 2005 through 2007 to evaluate the effects of simulated herbicide drift on ‘Cocodrie’ rice. Each application was made with the spray volume varying proportionally to herbicide dosage based on a constant spray volume of 234 L ha−1 and an imazethapyr rate of 70 g ai ha−1. The 6.3%, 4.4 g ha−1, herbicide rate was applied at a spray volume of 15 L ha−1 and the 12.5%, 8.7 g ha−1, herbicide rate was applied at a spray volume of 29 L ha−1. An application of imazethapyr at one-tiller, panicle differentiation (PD), and boot resulted in increased crop injury compared with the nontreated rice. The most injury observed occurred on rice treated at the one-tiller timing. Imazethapyr at one-tiller, PD, and boot reduced plant height at harvest and primary and total (primary plus ratoon) crop yield, with the greatest reduction in primary crop yield resulting from imazethapyr applied at boot. Imazethapyr did not affect rice treated at primary crop maturity.

Estudios de campo se realizaron cerca de Crowley, Louisiana del 2005 al 2007 para evaluar los efectos de la deriva de herbicida simulada sobre arroz ‘Cocodrie’. Cada aplicación se hizo con un volumen que varió proporcionalmente a la dosis del herbicida con base en un volumen constante de 234 L ha-1 y una dosis de imazethapyr de 70 g ai ha-1. La dosis de herbicida de 6.3%, 4.4 g ha-1, fue aplicada a un volumen de 15 L ha-1, y la de 12.5%, 8.7 g ha-1, se aplicó con un volumen de 29 L ha-1. Una aplicación de imazethapyr a 1-retoño, diferenciación de la panícula (PD), y engrosamiento de la vaina, resultó en un aumento en el daño del cultivo en comparación con el plantas no tratadas. El mayor daño observado ocurrió en arroz tratado en la etapa de 1-retoño. Imazethapyr a 1-retoño, PD y engrosamiento de la vaina redujo la altura de la planta al momento de la cosecha y el rendimiento primario y total (primario más soca), con una reducción mayor en el rendimiento primario como resultado del imazethapyr aplicado durante el engrosamiento de la vaina. El imazethapyr no afectó el arroz tratado en la madurez del cultivo primario.
