Abstract

Understanding the persistence of PRE-applied pendimethalin is important in determining timing of subsequent weed management programs in sugarcane on organic soils in the Everglades Agricultural Area (EAA). Dissipation of oil- and water-based pendimethalin formulations applied PRE at 2, 4, and 8 kg ai ha−1 were compared in 2011 and 2012 on organic soils in the EAA. The rate of dissipation of both formulations was very similar. Both formulations had an initial rapid rate of dissipation followed by a slower rate of dissipation. However, the initial amount of pendimethalin in the soil was higher with the water-based compared to the oil-based formulation, most likely because of the lower volatility of the water-based formulation. The half-lives (DT50s) of the oil-based formulation were 32, 18, and 10 d and 8, 8, and 12 d at 2, 4, and 8 kg ha−1, respectively, in 2011 and 2012, respectively. The DT50s of the water-based formulation were 20, 13, and 10 d and 12, 12, and 14 d at 2, 4, and 8 kg ha−1, respectively in 2011 and 2012, respectively. These DT50 values were attributed to low soil water content as well as the absence of incorporation following application. Our results suggest that dissipation of pendimethalin is rapid on organic soils irrespective of the formulation when applied under dry soil conditions with no incorporation into the soil.

Entender la persistencia de aplicaciones PRE de pendimethalin es importante para determinar el momento de implementación de programas de manejo de malezas subsiguientes en caña de azúcar en suelos orgánicos en el Área Agrícola de los Everglades (EAA). En 2011 y 2012, se comparó la disipación de formulaciones de pendimethalin a base de aceite y de agua aplicadas PRE a 2, 4, y 8 kg ai ha−1 en suelos orgánicos en el EAA. La tasa de disipación de ambas formulaciones fue muy similar. Ambas formulaciones tuvieron una tasa inicial de disipación rápida seguida de una tasa de disipación más lenta. Sin embargo, la cantidad inicial de pendimethalin en el suelo fue mayor con la formulación a base de agua en comparación con la formulación a base de aceite. Esto es probable que se debiera a la baja volatilidad de la formulación a base de agua. Las vidas medias (DT50s) de la formulación a base de aceite fueron 32, 18, y 10 d y 8, 8, y 12 d a 2, 4, y 8 kg ha−1, en 2011 y 2012, respectivamente. Las DT50s de la formulación a base de agua fueron 20, 13, y 10 d y 12, 12, y 14 d a 2, 4, y 8 kg ha−1, en 2011 y 2012, respectivamente. Estos valores de DT50s fueron atribuidos al bajo nivel de humedad de suelo y a la ausencia de incorporación después de la aplicación. Nuestros resultados sugieren que la disipación de pendimethalin es rápida en suelos orgánicos independientemente de la formulación cuando se aplica sin incorporación a suelos en condiciones secas.
