Abstract

After 10 months, diphenamid residues were found throughout the 0–9 inch soil depth. In silt loam soils under climatic conditions prevailing in and around the bluegrass region of Kentucky, diphenamid residues in soils may be present at phytotoxic levels in the plow layer 10–11 months after application at rates required for weed control in tobacco.
