Eighteen bacterial strains were isolated from wilted anthurium plants collected in Holi and Puli areas of central Taiwan. Based on their morphology, physiological and biochemical properties and pathogenicity to anthurium, they were identified as Pseudomonas solanacearum E. F. Smith. All strains were race 1 and biovar 4. The symptoms were manifest first in the yellowing of portion of the outer leaf which gradually expanded to the entire area of the leaf, and then progressed to inner leaves. Finally systemic yellowing and wilting resulted in the plant death. Under warm and moist conditions, the bud and tissues adjcent to basal stem sometimes showed brown rot symptoms. Among eight cultivars of anthurium tested, Lydia-420 and TART No. 4 were moderately resistant, while others susceptible. Strains of P. solanacearum from anthurium were pathogenic to solanaceous hosts and peanut. Strains from bird-of-paradise and cat-tail willow were pathogenic to anthurium but strains from perilla, tomato and tobacco were not pathogenic to anthurium. The diseased anthurium field in Holi was very close to bird-of-paradise fields where wilting of the plants induced by P. solanacearum was observed. However, three strains of P. solanacearum from anthurium tested could not infect bird-of-paradise. Field observation revealed that bacteriol wilt of anthurium has limited occurrence and was restricted to the fields where unfermented barks had been used as the covering material for plant bed.
