According to physiological, biochemical tests and multilocus phylogenetic analysis (gyrB, rpoD, and rpoB), 25 were characterized as P. mediterranea, five as P. viridiflava, three as P. corrugata, and one as P. marginalis. All of them produced necrotic lesions and pith hollowing in re-inoculated tomato plants. Some P. mediterranea isolates (UYT92018, UYT122018, UYT192018, UYT222018, and UYT372018 from season 2018) did not develop a hypersensitive response (HR) in tobacco like the other P. mediterranea, P. corrugata, P. viridiflava, and P. marginalis isolates. According to our knowledge, this is the first documented report of P. viridiflava and P. marginalis causing tomato pith necrosis in Uruguay. As well as the presence of several Pseudomonas spp. causing tomato pith necrosis in the Salto area P. mediterranea was confirmed to be the most prevalent. © 2023, Koninklijke Nederlandse Planteziektenkundige Vereniging.  aP. corrugata  aP. marginalis  aP. viridiflava  aPseudomonas mediterranea  aSolanum lycopersicum1 aMAESO, D.1 aCATARA, V.1 aRUBIO, L.1 aLEONI, C.1 aAMARAL, J.1 aESTELDA, C.1 aHERNÁNDEZ, M.1 aBÓFFANO, L.1 aGONZÁLEZ, P.  tEuropean Journal of Plant Pathology, 2023, volume 165, issue 4, pp.715-724. doi: https://doi.org/10.1007/s10658-023-02639-6
