Abstract

Trunk diseases cause slow decline and loss in productivity of grapevine. In surveys carried out from 2010 to 2012 in vineyards in Baja California (Mexico), fungal isolates were obtained from Cabernet Sauvignon grapevines with cankers. Morphological studies and phylogenetic analyses, using the internal transcribed spacer (ITS) region of the rDNA and a partial sequence of the β-tubulin gene, identified two isolates as Eutypella microtheca. Pathogenicity tests, using grapevine green tissue, fulfilled Koch´s postulates. To our knowledge, this is the first report of E. microtheca occurring on grapevine in Mexico and highlights the need of considering this fungus as another potential threat to vineyards in this region.
