Xanthomonas fragaria is an exotic bacterial pathogen of strawberry. The pest poses a significant production threat to the strawberry market. Angular leaf spot (ALS) disease primarily destroys the leaves of strawberry plants and on occasions, also affects the plant's flowers. It does not affect the fruit grown on infected plants, but has the potential to significantly reduce the performance and yield capacity of an infected strawberry crop. The bacterium does not affect human health.
