Maize is the most important cereal food crop. It is subjected to
infection with many viruses. A survey on viruses affecting maize was
conducted in El-Monfia, Kafr-El-Sheikh, Al Ismailia, and El-Menia
Governorates in 2010 and 2011 seasons. In addetion, weeds existed in maize
field were also rested. Maize dwarf mosaic virus (MDMV) is the most
economically significant virus infecting maize crop in Egypt. The percentage
of infection differs from one location to another. MDMV was isolated from
naturally infected maize plants at El-Monfia. These samples were checked
for virus presence using Indirect ELISA. A number of cultural practices were
evaluated as control measures against MDMV to minimize the virus
infection in maize crop.
