【 摘 要 】

Little information is available on the behavior of thiamethoxam in soils, whereas many studies show the effect of phosphate and vinasse in soils in Brazil. This study evaluated the sorption, desorption and retention of thiamethoxam in vinasse- and phosphate-amended samples of a dystrophic Red-Yellow Latosol (LVAd) and a distroferric Red Latosol (LVdf). The LVAd presented higher sorption of thiamethoxam. Phosphate did not affect the sorption or retention and vinasse increased the interaction of the compound with the soil particles, reducing desorption to the soil solution.
