Abstract: Field plots were established to evaluate the efficacy of late-season applications of ManKocide for the suppression of Xanthomonas hortorum pv. carotae (Xhc) on harvested carrot seed. Two ManKocide applications were made in mid to late August 2014 in each of two fields, and harvested seed from the plots was assayed by plating dilutions of seed washes onto a semi-selective agar medium. Late season applications of ManKocide did not significantly reduce Xhc populations on harvested seed in this study.
