The author summarizes the data of literature and own investigations about an involving, geographic spreading and injurious action of viruses of vegetables crops on the Southern region of Russian Far East. The taxonomy, symptomology, modes of infection by different viruses and protective measures were described. The biological and physicochemical properties viral isolates obtained from plants with different lesion symptoms were determined. The author attends the use high sensitive methods for identification injurious viruses (biological tests, electron microscopy, immunodiag-nostic) and the creation of diagnostic species- and strain specific serums.
