Synopsis Rates of 2 lb./A. or more of 2‐chloro‐4‐ ethylamino‐6‐isopropylamino‐ s ‐triazine (Atrazine) or 2‐ methoxy‐4,6‐bis (isopropylamino) ‐s‐triazine (Prometone) were necessary to give satisfactory weed control during the fallow period in an alternate wheat fallow rotation. However, these rates frequently injured the following wheat crop. Climatic and edaphic factors affected phytotoxicity and soil persistence of the herbicides.
