For all cultivars, paraquat at 0.25 kg/ha was applied when at least 70% of the seed pods had reached a mature brown color and when seed moisure was 25% or less. Cultivars were harvested within 3 to 5 d when seed moisture was approximately 12%. No yield obtained with Santa Rosa. Abbreviations: C, conventional cultivars; RR, Roundup Ready cultivars.
