Abstract: Oxyfluorfen exhibited intraspecific selectivity among cabbage ( Brassica oleracea L. var capitata) cultivars. The wettable powder (WP) and granular (G) formulations were less toxic to cabbage plants than the emulsifiable concentrate (EC) formulation when applied at 0.56 kg ai/ha. Susceptibility to oxyfluorfen injury decreased with plant age. Plants treated with 0.56 kg ai/ha of the WP formulation at the 2-leaf growth stage showed greater injury than plants treated at the 6–8 leaf stage. Oxyfluorfen injury symptoms from an application of 0.28 kg ai/ha EC formulation were increased when plants were treated previously with 1.12 kg ai/ha EPTC. Selectivity may be provided by cuticular wax on the cabbage leaves which prevents spray retention and penetration. Cultivars with increased cuticular wax showed reduced injury from oxyfluorfen application.
