Preemergence Weed Control in Row Middles of Polyethylene-Mulched Cauliflower (Brassica oleracea)

Four experiments were conducted in 1985 and 1986 at three locations to assess weed control efficacy and phytotoxicity of several preemergence herbicides applied between beds (row middles) of polyethylene-mulched cauliflower grown on raised beds. Efficacy of most herbicide treatments varied among the four experiments; however, 4.5 kg ai/ha diethatyl and tank mixes of oxyfluorfen with cinmethylin consistently controlled weeds best. Plant stand, yield, and cauliflower curd size were not affected by treatment for any of the varieties used at any of the locations.
