Diruon [3-(3,4-dichlorophenyl)-1,1-dimethylurea], linuron [3-(3,4-dichlorophenyl)-1-methoxy-1-methylurea], fenac [(2,3,6-trichlorophenyl)acetic acid], and trifluralin (α,α,α-trifluoro-2,6-dinitro- N,N-dipropyl-p-toluidine) were applied to plots designed for sampling surface runoff. Over a 3-year period, highest concentrations in runoff were usually associated with rainstorms that occurred soon after application. Maximum seasonal losses were < 0.12, 0.30, 2.90, and 0.05% of the applied diuron, linuron, fenac, and trifluralin, respectively. The data suggest that with proper use on agricultural land in the lower Mississippi River Valley these herbicides pose little threat to adjacent aquatic areas.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
