Zlatna žutica vinove loze u Hrvatskoj

Neki mikrobni biljni patogeni i njihovi kukci-vektori nalaze se na listama invazivnih vrsta, a ulaskom u nove ekosisteme uspostavljaju u njima i vrlo štetne patosisteme. Takav je slučaj s nekultivabilnom bakterijom roda 'Candidatus Phytoplasma', uzročnikom bolesti vinove loze Flavescence dorée (FD, zlatna žutica) i njenim vektorom Scaphoideus titanus Ball. Prisutnost fitoplazme Flavescence dorée (FD) prvi je put utvrđena u pavitini (Clematis vitalba L.) 2007. u Istri. Već 2008. zabilježena je i u Međimurskoj županiji. Na vinovoj lozi je utvrđena 2009. u Vivodini. Fitoplazma FD je do sada potvrđena u vinovoj lozi iz 5 županija kontinentalne Hrvatske. Osim nalaza u biljkama-domaćinima, potvrđena je i zaraženost američkog cvrčka S. titanus u vinogradima zaraženima ovom fitoplazmom. S. titanus je prvi puta nađen u Europi 1958. godine, a kao FD-vektor potvrđen je u Francuskoj 1963. Invazivna je vrsta, no nažalost već i udomaćena u većini zemalja našeg okruženja. Paralelno, unatoč poduzetim fitosanitarnim mjerama, i broj pozitivnih nalaza fitoplazme FD se iz godine u godinu povećava. Uzevši u obzir nalaze u zemljama regije (Srbija, Slovenija), te veliku populaciju američkog cvrčka u svim vinorodnim područjima Hrvatske, postoji opasnost da se širenje zlatne žutice ubrza. Trenutno je na snazi „Naredba o poduzimanju mjera za sprječavanje širenja i suzbijanje zlatne žutice vinove loze koju prouzrokuje štetni organizam Grapevine flavescence dorée“ (NN 07/13). Some microbial plant pathogens and their insect vectors are listed as invasive species. Upon introduction to new ecosystems, harmful pathosystems are also established. This was the case with the grapevine Flavescence Dorée agent, an uncultivable bacterium of the ‘Candidatus Phytoplasma’ taxon, and its insect vector Scaphoideus titanus Ball. Flavescence dorée phytoplasma (FD) was for the first time detected in an Istrian Clematis vitalba L. in 2007 and further recorded in Međimurje one year later. In 2009, it was identified for the first time in its main host, the grapevine, in Vivodina. To date, FD phytoplasma occurrence has been confirmed in 5 counties of continental Croatia. Insect vectoring the disease, S. titanus, was recorded in Europe in 1958 and identified as the only FD vector in France in 1963. It is invasive insect now established in all Croatian grapevine growing regions and it was found infected by FD phytoplasma in infected vineyards. Despite all undertaken phytosanitary measures, the number of FD findings, both in grapevine and in insects, is growing yearly. Frequent FD outbreaks in neighbouring countries (Slovenia, Serbia) and large S. titanus populations present in Croatia suggest a high risk for further disease spread in the country. The “Ordinance on protective and control measures to prevent the spread of the Grapevine flavescence dorée” is currently in force (National Gazette 07/13).
