A population of sweet corn (Zea mays) grown during the 19791980 rainy seasons in Brasília was heavily attacked by a bacterium causing top and stalk rot. About 37% of the plants showed symptoms, and 24% died within 45 days of planting. The bacterium was identified as Erwinia chrysanthemi pv. zeae. This is believed to be the first report of this pathogen on corn in Brazil.
