Bokshan O. Interception and diagnostics of quarantine bacterioses: fire blight and potato brown rot

For the first time in Transcarpathian region (2003) is intercepted and diagnosed the causal agent of a fire blight - E.amylovora. It is established, that in conditions of Transcarpathian region development of disease differs from its classical description by absence of exudate and character of cankers on branches. The greatest risk of exhibiting of symptoms of fire blight in conditions of Ukraine gets to the season of intensive growth of trees. The various sensibilities of varieties to the causal agent of fire blight at a pear and an apple are established. For forecasting of fire blight appearance and development it is recom-mended to use Maryblyt model. The scheme of an immunization of rabbits for obtaining of highly specific serums, parameters of an erythrocital diagnosticum to E.amylovora operating time, schemes of accelerated diagnostics E.amylovora and R. solanacearum, preparation of paper indicatory disks for enzyme-indication of phyto-pathogenic bacteria is proposed.
