Abstract:Sulfentrazone is a mobile herbicide in the soil that can reach groundwater. The objective of this study was to verify the leaching of sulfentrazone in samples from three Brazilian "Cerrado" soils, and compare the biological with the chromatographic method to determine the leaching. The soils were PVC columns (10 cm in diameter x 50 cm in length), 1.5 kg ha -1 of sulfentrazone was applied to the top of the columns. Twelve hours after the application of the herbicide, they were submitted to simulated rainfall (6… Show more
