Pseudomonas syringae pv. syringae isolated from lilac was inoculated to 133 species of economic woody plants and the symptoms of each plant were surveyed. Severe necrotic symptoms were formed on twigs or leaves of 36 species. The symptoms with extended necrosis were observed on 38 species and stationary necrotic spots on 57 species. No symptom occurred on 2 species. The early defoliation occurred on 26 species. From these results, the parasitism of the present bacterium was recognized on 74 species.
