Among the bacterial strains isolated from diseased sunflower leaves, eight were studied in some detail. A fluorescent pseudomonad isolated from necrotic tissues and its reisolates belong to group Ia of phytopathogenic pseudomonads which includes Pseudomonas syringae bacterium. A study of host range indicated that the pathogen infects only sunflower but not the other plant species. Based on the pathogenicity study and biochemical and physiological tests, it was concluded that the pathogen belongs to the bacterium Pseudomonas syringae pv. helianthi .
