Oxyfluorfen applied preemergence at 0.14, 0.28, and 0.56 kg ai/ha reduced stand of direct-seeded broccoli 40 to 99%, while BAS 514 applied at the same rates did not reduce stand. Broccoli plants that survived oxyfluorfen exhibited 32 to 97% injury 6 to 9 weeks after treatment. BAS 514 at 0.14, 0.28, and 0.56 kg ai/ha caused 6 to 35% crop injury. Oxyfluorfen at 0.28 and 0.56 kg/ha reduced yield compared to the cultivated check at all locations. At one location, all rates of BAS 514 reduced broccoli yield compared to the cultivated check. The two low rates of oxyfluorfen and the two high rates of BAS 514 delayed crop maturity approximately 1 week at one location.
