This study determined the presence of Lasiodiplodia theobromae in citrus trees with deterioration and descending death in the central area of Tamaulipas, Mexico in 2017 and 2018. In the study area, plant samples were collected in the trees of valencia orange, grapefruit, mandarin and Italian lemon. In the laboratory, the samples were processed and the fungi were isolated and identified with taxonomic keys and by genetic analysis of the transcribed internal spacer and elongation factor 1 alpha TEF1. 33 strains of fungi were isolated in the 19 commercial citrus orchards, 26 belonged to the genus Lasiodiplodia sp., 3 of Botryosphaeria sp., 1 of Colletotrichum sp., 1 of Cyphellophora sp., 1 of Fusarium sp., and 1 of Nigrospora sp.
