Carrot (Daucus carota) and weed response to linuron and metribuzin applied at different crop stages Academic Article

abstract

• Redroot pigweed and common lambsquarters control was variable within and between seasons when postemergence linuron and metribuzin were applied one or two times at below-labeled rates to one-, three-, or five-leaf carrots. A single, low-rate application of either herbicide at the one- or three-leaf stage of carrots failed to provide adequate season-long broadleaf weed control. Two low-rate applications to either one- + three- or three- + five-leaf carrots significantly improved control. Linuron produced little or no injury to carrots regardless of application timing. Metribuzin induced injury was variable initially and decreased to 10% or less by 14 d after treatment. One application of either linuron or metribuzin resulted in reduced yields of carrots.
