Abstract
Summary
The presented study was created on the basis of the assignment of the Scientific Committee of Phytosanitary and Environment for the purpose of analysing information on the risk of spreading the spectrum of new bacterial pathogens of crops from available sources (EPPO database, information from the monitoring and survey of the spectrum of the specialized workplace Phytobacteriology of the Crop Research Institute in Prague). The study includes a total of 26 selected entities of bacterial plant pathogens with an increased risk of their introduction into the Czech Republic due to non‐compliance with phytosanitary measures and the possibility of rapid adaptation to domestic climatic conditions due to increasing temperature parameters. The selected spectrum of entities also includes bacterial pathogens regulated in the Czech Republic with the potential for rapid spread and the emergence of a disease epidemic with a serious impact on agricultural production. The prepared list includes entities classified according to the current system to the following classes and families: (i) Betaproteobacteria (2) ‐ Burkholderiaceae (1), Ralstoniaceae (1); (ii) Gammaproteobacteria (20) ‐ Xanthomonadaceae (15), Pseudomonadaceae (2), Enterobacteriaceae (3); (iii) Actinobacteria (4) ‐ Microbacteriaceae (4).
