The climatic conditions of continuous rains and high temperatures prevailing during 2014/2015 rice crop season, due to the occurrence of the "Ni?o phenomenon", were very favorable for the development of fungal diseases in rice cultivation. Among pathogens that attack rice and produce foliar spots, Alternaria padwickii (Trichoconiella padwickii (Ganguly) Jain) is mentioned. This fungus also affects the grain of rice panicles, affecting the quality and seed germination. In the rice crop season 2014/2015, a high incidence of foliar spots was observed in the rice field. At this situation a phytopathological diagnosis was made in order to detect the occurrence of A. padwickii in the crop, to describe the morphological characterization of the fungus and its prevalence in the Departments of Itap?a, Misiones and Caazap
