In 2020, leaf spots were observed on Datura innoxia plants in Curitiba, Brazil. Alternaria alternata was identified after isolation from symptomatic leaves through morphological characterization, along with sequencing of the partial tef, gapdh, and rpb2 genes and phylogenetic analysis. Pathogenicity was proven using Koch's Postulates. This is the first report of this species causing disease in Datura spp. worldwide.
