The results of the study have been published in Pest Management Science and underscore the need to stop this vicious circle by developing alternative disease control methods and new banana varieties. Black leaf streak disease is the most important banana disease worldwide. Cavendish bananas represent more than 50% of the global production - and dominate the export (95%) – but are very susceptible to this disease.
