Importance and distribution

Neoascochyta comprises thirteen species known on Poaceae and Rosaceae. Some species are pathogenic and cause leaf scorch (Golzar et al. 2019). Neoascochyta has been reported from Asia (China (Guizhou), Thailand), Europe (Germany, Italy, Norway, Romania), New Zealand, South America (Argentina) and The United States.
