Origin: Asia.
Habitat: May sometimes escape from cultivation in NYC.
Notes: Mimosa wilt is the most destructive disease affecting A. julibrissin. It is caused by Fusarium oxysporum f. sp. pernicosum (Deuteromycotina, Hyphomycetes). The first external symptom is yellowing, drooping leaves, but brown streaks in the sapwood appear before leaves wilt. This disease can kill a tree within weeks or months. The pathogen is present in the soil as spores, which germinate in contact with small roots. Mimosa is also attacked by Ganoderma lucidum, another root fungus (see Sassafras). Wounded trees may be infected by Oxyporus latimarginatus (see Hackberry) and Nectria cinnabarina, Coral spot canker (Sinclair et al. 1987). Leaves eaten by twobanded Japanese weevil, Callirhopalus bifasciatus (Johnson and Lyon 1991).
