Abstract : Symptoms of mango malformation disease (MMD) were observed for the first time in April 2006 in three mango orchards in the Axarquia Region in southern Spain. Symptoms included an abnormal development of vegetative shoots with shorted internodes and dwarfe3d leaves and hypertrophied short and thickened panicles. In 2006, 2009 and 2010, isolates of Fusarium were obtained from vegetative shoots and floral tissue of symptomatic mango trees from 21 different orchards of cultivars Keitt, Kent, Osteen, Tommy atkins and a variety of minor commercial cultivars, all showing typical symptoms of MMD. Different Fusarium-like strains were isolated from infected tissues. Morphological, molecular genetic and pathogenicity tests identified the causal agent of MMD as Fusarium mangiferae. This is thought to be the first report of MMD caused by F. mangiferae in Spain and Europe.
