Abstract		The research on phytoplasma in Slovenia is indicating their increased phytopathological and economical impact. In Slovenia the presence of the following phytoplasma diseases of woody plants have been established: Grapevine yellows, European stone fruit yellows, Apple proliferation, and Pear decline. Grapevine yellows are present primarily in Primorska wine growing region, and were found to be in an escalated progression in Posavje and Podravje regions. Laboratory analyses confirmed the presence of Aster yellows and Stolbur phytoplasma. The occurrence of Flavescence doree has not been yet fully confirmed in Slovenia. Vector of FD, Scaphoideus titanus is widely spread only in vineyards of Primorska region. The presence of Hyalestes obsoletus, the vector of BN has been established in Primorska region, but not in the vineyards. Aprcot chlorotic leafroll (ESFY) is a new disease in Slovenia, which was noticed from 1989 in West and South West parts on peaches, apricots and plums of a Chinese-Japanese origin. The disease is observed to be in a gradual progression. Apple proliferation is present in Slovenia, and it is becoming an economically important disease. Pear decline has not been extensively investigated in Slovenia, but there are some clear indications for its presence. Although the presence of potential vectors of all above mentioned phytoplasma was established in Slovenia, their spread and specially their vectoring potential remain to be investigated.
Summary		Dosedanje raziskave fitoplazmatskih bolezni v Sloveniji kažejo, da se njihov fitopatološki in gospodarski pomen povečuje. Na ozemlju Slovenije so doslej ugotovljene naslednje fitoplazmatske bolezni lesnatih rastlin: trsne rumenice /Grapevine yellows/, leptonekroza koščičarjev (European srone fruit yellows phytoplasmal, metličavost jablan /Apple proliferation) in umiranje hrušk /Pear decline). Trsne rumenice so razširjene predvsem v primorski vinorodni deželi, širijo pa se tudi v posavski in podravski vinorodni deželi. Laboratorijsko sta potrjeni prisotnosti trsnih rumenic vrste Aster yellows in Srolbur (Bois noir/. Pojavljanje zlate trsne rumenice (Flavescence doree) doslej v Sloveniji ni bilo nesporno ugorovljeno. Vektor FD Scaphoideus iironus je splošno razširjen le v primorskih vinogradih. Prisotnost vrste Hyalesies obsoletus, kot prenašalke BN v vinogradih doslej ni bila ugotovljena, pač pa le zunaj njih. Leptonekroza koščičarjev /ESFY/ je za Slovenijo nova bolezen in se pojavlja od leta 1989 v njenem zahodnem in jugozahodnem delu na breskvah, marelicah in slivah kitajsko-japonskega porekla. Bolezen je v postopni progresiji. Metličavost jablan je v Sloveniji splošno razširjena in ima že gospodarsko škodljive razsežnosti. Umiranje hrušk /PDJ je na ozemlju Slovenije še slabo raziskano, laboratorijske analize v letu 2000 potrjujejo njeno navzočnost v zahodni Sloveniji. Vsi najpomembnejši potencialni vektorji omenjenih fitoplazem so na ozemlju Slovenije prisotni, njihov vektorski potencial pa je še zelo slabo raziskan.
