During the spring of 2006, we observed a decay of calla plants grown in plastic houses in two locations in Serbia. A soft rot type of symptoms indicated possible bacterial etiology of the disease. After microscopic examination of the diseased tissue we carried out a procedure for isolation of phytopathogenic bacteria from above and underground plant parts. The symptoms of natural infection were reproduced by testing the ground plant parts. The symptoms of natural infection were reproduced by testing the pathogenicity of the bacterial strains associated with the diseased calla plants. Based on results of bacterial tests Pectobacterium carotovorum subsp. carotovorum was identified as a causal agent of calla tuber and stem base in Serbia.
