Bacterial blight of peas was found in New York State in 1979 after not being observed there for more than 25 years. The disease was not observed in 1980. The pathogen was identified as Pseudomonas syringae pv. pisi rather than P. syringae pv. syringae; both induce the same symptoms in the field. The disease was associated only with plants grown from one seed lot. The pathogen was not recovered from seeds assayed in the laboratory.
