Among pests, corn borers, swedish flies, aphids and cutworms cause great harm to corn. They cause significant damage to crops, the total yield can be reduced by 30-35%. About 3000 phytoviruses are known in the world. By the beginning of the 21st century, 1000 viruses have been described , of which more than 200 species of viruses that infect cereals have been identified, which are assigned to the families Bromoviridae, Potyviridae, Rhabdoviridae, Luteviridae [1]. Of these viruses, the most common is the dwarf mosaic virus. Maize dwarf mosaic potyvirus ( MDMV ) causes a characteristic mosaic lesion of leaf blades.
