Bacterial spot and rot of cauliflower and lettuce heads become more and more a frequent and economically important phenomenon in Yugoslavia. Its increased spreading affects remarkably the duration, freshness and general outlook of the diseased cauliflower and lettuce heads. On the basis of this results obtained, it can be seen that the following pathogens exist on cauliflower heads: Pseudomonas cichorii (Swingle) Stapp, P. marginalis pv. marginalis (Brown) Stevens and P. viridiflava (Brukholder) Dowson. The same bacteria (P. cicchorii, P. m. pv. marginalis and P. viridiflava) were isolated from the diseased lettuce, as well as Erwinia carotovora subsp. carotovora (Jones) Bergey et al., which during the present work, has not been identified among isolates originating from cauliflower heads. Except of E. c. ssp. carotovora and P. viridiflava, other two identified (P. cichorii and P. m. pv. marginalis) represent the first records of pathogens in Yugoslavia.
