Abstract

Movement of 2-methoxy-3,6-dichlorobenzoic acid (dicamba) and N,N-dimethyl-2,2-diphenylacetamide (diphenamid) in Hagerstown silty clay was greater with either 5 or 10 surface inches of water when the water was applied in 0.25-inch increments rather than 1-inch. Upward movement of these herbicides occurred under sub-irrigation and when surface-applied water was allowed to evaporate freely from the soil surface. Dicamba always moved more readily than diphenamid. The results indicate that weather patterns may be important in addition to total rainfall in determining the movement of herbicides in soil.
