The most common bacterial diseases on potatoes are caused by pectolytic Erwinias namely, Erwinia carotovora subsp.atroseptica (Eca), E.carotovora subsp. Carotovora (Ecc) and Erwinia (Ech). chrysanthemi (Ech). Direct and indirect crop losses due to these pathogens are considerable, especially in certain production areas.
