Importance
X. fragariae was first reported on strawberries in 1960 in Minnesota.[3] It is now found throughout many American states, Europe, South America, Africa, Australia, and New Zealand.[5] X. fragariae does not have a large host range, it infects different strawberry varieties, including Fragaria virginiana and F. vesca, along with Potentilla fruticosa, and P. glandulosa.[6] Even though X. fragariae has a small host range, it is capable of causing major damage. Angular Leaf Spot, caused by X. fragariae, can cause up to 75% yield reduction of strawberries.[2] Angular Leaf Spot is currently an issue in strawberry nursery production, leading to problems in transporting strawberry plants throughout the U.S and over to Europe.[5] Xanthomonas fragariae is not only an issue transporting young plants, but infected fruits can lead to a symptom known as “black cap” that can reduce the quality and marketability of the fruit.[5]
