Stewart's disease of corn (Zea mays), caused by the bacterium Pantoea stewartii, is economically important in both sweet corn and seed corn. EPPO considers P. stewartii as an A-2 quarantine pest and it is also of quarantine significance for APPPC and IAPSC. The corn flea beetle, Chaetocnema pulicaria Melsh, is an important component in this pathosystem, as it is the overwintering habitat for P. stewartii, and as a vector, it provides the primary mode of transmitting the bacterium in seed corn fields, zero-tolerance phytosanitary regulations limit the export of seed corn from the United States to other countries if Stewarti's disease is found in seed corn fields EPPO recommends (OEPP/EPPO, 1990) growing season inspection of seed crops as a specific quarantine requiremrnt, but is currently evaluating seed test methods.
