PAES, José M. V. et al. Dimethenamid movement in different soils. Planta daninha [online]. 1999, vol.17, n.1, pp.31-39. ISSN 0100-8358.

The mobility of herbicide dimethenamid in sand and soils from Monte Santo (sandy clay loam), Sete Lagoas (clay) and Três Marias (loamy sand) - MG was evaluated in greenhouse conditions using bioassay methodology. The herbicide was applied to the soil at a dose of 1.125 kg i.a. ha-1. After product application, a rainfall (45 and 90 mm) was simulated on top of column containing the samples. The experimental layout was randomized block design with 4 replications in a factorial scheme. The dimethenamid was strongly leached in sand substract. In the Três Marias soil dimethenamid achieved 10 to 15 cm depth with 45 mm rainfall simulation and 20 to 30 cm when 90 mm rainfall was used. Monte Santo and Sete Lagoas soils had a similar leaching behavior remaining in the first 5 cm of column.
