Importance and role

Importance of genus to ecosystem

Species of Neoascochyta are saprobic and are involved in nutrient recycling in the ecosystem. Some species are pathogenic and cause leaf scorch (Golzar et al. 2019).


Industrial relevance and applications

There are currently no industrial applications of Neoascochyta.


Quarantine significance

No biocontrol agent has been reported from Neoascochyta. Neoascochyta species cause leaf scorch on wheat in Australia (Golzar et al. 2019). They may have potential role in controlling some pathogens. Further studies are needed.


Biochemical importance of the genus, chemical diversity or applications

The chemical diversity of Neoascochyta has not been investigated.


Diversity of the genus

Neoascochyta comprises thirteen species known on two plant families namely Poaceae and Rosaceae. Neoascochyta has been reported from Buenos Aires, Free State, Germany, Great Britain, Guizhou, Italy, New Zealand, Norway, Romania, Thailand and United States. Many hosts and regions are still understudied for the genus. Many species of Neoascochyta can be discovered from future studies.
