Xanthomonas campestris pv. vesicatoria in Ohio

In 1993, 70 samples from pepper (Capsicum annum) have been collected on plants showing symptoms of bacterial spot from commercial fields and private gardens in Ohio (US). Xanthomonas campestris pv. vesicatoria (EPPO A2 quarantine pest) has been isolated and races were identified by using a set of differential lines of pepper (derived from and including 'Early Calwonder'). The majority of the strains (55 %) were identified as race 3, 15 % were race 1, 16 % were race 2; the remaining 14 % could not be identified with the differential lines used. The disease is widespread in USA (Arizona, California, Florida, Georgia, Hawaii, Iowa, Michigan, North Carolina, Oklahoma), but the EPPO Secretariat, had previously no data on X. campestris pv. vesicatoria in Ohio.
