Leaf spot and blight of Dieffenbachia amoena caused by Pseudomonas marginalis pv. marginalis are described for the first time. Symptoms were noticed during winter on plants in the greenhouse, the first signs were small, elongated, light brown lesions on the surface of the leaves. As the infection spreads, leaves become completely brown and collapse. The identity of the causal agent was determined by biochemical, nutritional and pathogenecity tests as well as by comparison of whole‐cell protein profiles of the isolates under study with those of type strains.
