Summary: 
Identification of the maize mosaic agent is performed 
studying its host plants, ways of transmission properties in 
Sap and morphology. 
Comparison of these properties with those described 
in literature resulted in establishing the fact that the 
virus isolated in the Ukraine is identical to that described 
in Europe (the maize mosaic virus) and the USA (the maize 
dwarf mosaic virus) as well as to the maize mosaic virus 
which is distributed in the Krasnodar territory.

Viral diseases of the maize are very common in different 
countries all over the world where this crop is being cultiva- 
ted, and cause huge economic losses. 
In the works by foreign researchers special attention 
is paid to the investigation to viral diseases of the maize 
(1-3). In the Soviet Union, maize viruses have not been fully 
studied. For the first time in 1964, T.S. Dubonosov and 
I. V. Panarin observed mosaic virus on maize crops in the 
Krasnodar region (4, 5). I.I. Mitrofanov has found the mosaic 
virus widespread in this region and described some of its 
properties (6, 7). 
Apart from the fact that significant areas in Ukraine 
are sown with maize there is now word in literature on viral 
infections occurring in maizee The aim of our work was to
