This study was conducted to evaluate leaching of herbicides flumioxazin and metribuzin under greenhouse conditions, in a Utisol and a Oxisol (collected in two differents agricultural regions in the state of Minas Gerais) soils in two moisture conditions (wet and dry soil). Simulation of rainfall ( 45 mm and 90 mm) was done after application of flumioxazin (60 g/ha) and metribuzin (384 g/ha) in columns containing two soils under wet and dry conditions. Flumioxazin did not leach beyond 5 cm from the surface when applied in the sandy-loam soil. In the sandy soil, this herbicide reached a depth of 10 cm from the surface in the column. Metribuzin presented great mobility in both soils and moisture conditions, reaching depth of 20 cm in wet sandy-loam soil and 45 cm in dry sandy soil.
