The microscopic fungus Cephalosporium maydis Samra, Sabet and Hingorani which causes late wilt disease in maize, has been isolated for the first time in Hungary. According to the literature the pathogen is only known at present to cause economic damage in Egypt and India. The fungus is seedborne, so it can be assumed that it reached Hungary through the import of infected propagation stock. It causes a disease of the vascular bundles, the first symptoms of which can be observed in maize at tasseling. Diseased plants have retarded development, then wilt and finally dry up. The vascular bundles become discoloured and cavities are formed in the pith. It is highly probable that global warning and the dry weather experienced in early summer over the last decade or so have played a decisive role in the appearance and activity of the pathogen in Hungary. If the climate continues to warm up, the significance of this disease could increase under Hungarian conditions, so it is important to carry out further studies both on the pathogen itself and on the resistance of cultivated hybrids and lines, and to elaborate effective methods of chemical control
