Abstract
Potato production provides one of the main sources for food production, processed either at home or by the industry. Plant diseases are often limiting factor in cultivation of this crop, leading to reduction of yield and tuber quality. Zebra chip disease, caused by a floem-limited bacterium, belonging to the genus Candidatus Liberibacter, is a new, economically important disease of potato and other solanaceous plants. It is widespread in commercial potato fields in USA, Mexico, Central America, New Zealand, and was recently reported in Europe. The disease reduces yield, but most significant damage occurs due to the symptom development on tubers and loss of their marketability. Given the importance of potato production in our country, the goal of this paper is to raise the awareness about the disease occurrence and distribution, discuss the main characteristics of this relatively unknown pathogen, detection and identification methods necessary for the successful and timely diagnosis, ep...idemiology, symptomatology and disease management.

Krompir je biljna vrsta čija proizvodnja ima veoma značajnu ulogu u obezbeđivanju hrane, a takođe i sirovine za industrijsku preradu. Pojava štetnih organizama neretko predstavlja ograničavajući faktor gajenja ove biljke, jer dovodi do smanjenja prinosa i pogoršanja kvaliteta krtola. Oboljenje nazvano zebrasti čips, koje prouzrokuje fastidiozna bakterija iz roda Candidatus Liberibacter, je novo, ekonomski značajno oboljenje biljaka iz familije Solanaceae, čiji je glavni domaćin krompir. Patogen, takođe, zaražava i srodne vrste kao što su paradajz i paprika. Ovo destruktivno oboljenje rasprostranjeno je u proizvodnim područjima Amerike, Novog Zelanda, a nedavno je otkriveno i na evropskom kontinentu. Kao posledica infekcije, dolazi do smanjenja prinosa zaraženih biljaka, dok najznačajnije štete nastaju usled pojave simptoma na krtolama i gubitka njihove tržišne vrednosti. S obzirom na značaj proizvodnje krompira, paradajza i paprike u našoj zemlji, cilj ovog rada je da se ukaže na pojav...u i rasprostranjenost oboljenja, glavne karakteristike ovog malo poznatog patogena, metode detekcije i identifikacije neophodne za pouzdanu i pravovremenu dijagnozu oboljenja, epidemiologiju, simptomatologiju i mere zaštite.
