Importance and distribution

Septocyta comprises five species known on Bedfordia sp. (Asteraceae), Corchorus capsularis (Malvaceae), Rosa indica (Rosaceae), causing leaf spots and purple blotch on Rubus sp. (Rosaceae), Senecio bedfordii (Asteraceae) and Viscum album (Santalaceae). Septocyta is reported from several countries such as Asia (India), Australia (Tasmania), Europe (Bulgaria, Germany, Poland, the United Kingdom), Union of Soviet Socialist Republics (USSR) amongst others

 

Quarantine significance

Septocyta is of quarantine significance as it causes destructive necrosis of floricanes in blackberry (Rubus fruticosus) in Europe (Adair et al. 2012). Septocyta is also in the controlled pest list of Japan (EPPO 2022).
