Maize dwarf mosaic virus caused epidemy on corn in Yugoslavia in 1989. Maize dwarf mosaic virus caused decrease of yield of field corn and severe losses of seed corn crops in 1989 in Yugoslavia. The yield of field corn crops was decreased for about 20%, but in some cases over 50% comparing to the average yield from previous years. At about 2/3 of the area with seed corn crops the yield was decreased about 70% but at some fields it was decreased over 90% comparing to the yield obtained in previous years. Because of maize dwarf mosaic severity many crops of seed corn were destroyed and plots plowed out. Because of the possibility of epidemics like in 1989, maize dwarf mosaic, which is present in Yugoslavia as well as in other countries, is a great danger to corn production. Therefore it is necessary to study continuously this disease from different points, especially the possibility of breeding corn for resistance.
