In Cuba, the emergence in recent years of dry rot in corms and cormels of taro constitute a negative factor for the traditional and safety way to store these rhizomes. In Central America, the Caribbean and Venezuela, the disease is considered a complex phenomenon in yield reduction. An important aspect of plant health surveillance is to update knowledge about the presence of harmful organisms in crops. Few researches have been developed in the search of resistant genotypes to this disease and the existence of mechanisms that govern this character is unknown. In order to know the organisms linked to such symptoms, samples of corms and comerls from different commercial growing areas in state and private enterprises in the country were collected. Samples were processed at the Laboratory of Plant Pathology. The two largest genera of highest incidence were Fusarium and Sclerotium, followed by Rhizoctonia. The presence of Penicillium, Trichoderma and Aspergillus is stood out, among others, as fungi associated to lesions.
