Conteúdo: | More 4-amino-3,5,6-trichloropicolinic acid (picloram) was detected in soil samples by soy- bean (Glycine max (L.) Merr., var. Ford) bioassay when the herbicide was applied in the fall than when it was applied in the spring to several pasture types. Downward movement was greater in sandy loam than in silty clay loam, Dissipation of picloram was greatest in the upper 12 inches regardless of soil types. More picloram was detected in the 24 to 36- inch depth from plots treated 1, 2, or 3 years before sampling than in plots sampled the year of treatment. This indicated downwards movement into the subsoil.
