Twelve brassica seed lots, naturally infected with Xanthomonas campestris pv.camprestris (Xee), were immersed in a 0.52% NaClO (1:10 clorox) aqueous solution of 5 ml/g seed at 50 53°C for up to 15 min. In eight lots, with pathogen counts of ≤5.3 x 106 CFU/10,000 seeds. Xee was not detected in liquid assay or direct plating of seeds following a 5 min soak treatment. In three more highly infected seed lots (9.0 x 106 2.1 x 108 CFU/10,000 seeds) a soak time of 15 min was necessary to control Xee. As a follow up, in one additional heavily infected seed lot(3.4% seed infection) the 15 min. treatment reduced infection considerably but did not eliminate Xee. The 5 min treatment did not significantly reduce in three lots after 10 min., and in four lots after 15 min. treatment. Average seed germination following all of the NaClO treatments was significantly higher than seed germination after hot water treatment at 50°C for 20 min.
