We conducted a sequential tracer leaching study on a field plot to investigate the temporal behavior of preferential flow to a field tile during an irrigation and subsequent rainfall events over a 14-d period. Two herbicides, along with the conservative tracer Br, were applied to a strip adjacent to a tile drain immediately before a 4.2-mm hr
