Xanthomonas cucurbitae is a species of Gram-negative bacteria that is a plant pathogen. It is the causal agent of bacterial spot disease of cucurbits, infecting plants like pumpkins, squash, and cucumbers.[1][2]

The disease can cause significant yield losses in commercial crops—up to 100% in some fields—particularly in pumpkin production in the Midwestern United States.[1][3][4] The bacterium was first identified on 'Hubbard squash' in New York in 1926.[1] It has since been found worldwide, with the first confirmed report in Europe occurring in Reggio Emilia, Italy, in 2018.[4]
