Abstrakt		The results of the previous research of the phytoplasma diseases indicate that their phytopatological and economic impact in Slovenia is increasing. The presence of the following phytoplasma diseases on woody plants have been confirmed in Slovenia: grapevine yellows, European stone fruit disease, pear decline, and apple proliferation disease. Grapevine yellows are present mainly in the grapevine growing areas of west and south west of Slovenia. However, the grapevine yellows have been reported to be present also in some parts of east and south of Slovenia. In all these regions, only the presence of the Stolbur type of grapevine yellows phytoplasma was confirmed by laboratory testing, indicating the presence of the Bois noir type of phytoplasma (BN). Interestingly, the occurrence of the Flavescence doree (FD) type of grapevine yellows phytoplasma was not established in Slovenia, although it's vector (Scaphotdeus titanus Ball) is commonly present in the vineyards of the west and south west of Slovenia. On the other hand, the vector of the BN type of grapevine yellows phytoplasma (Hyalesthes obsoletus) was recorded only on plants outside the vineyard and so far not inside the vineyards in west Slovenia. European stone fruit yellows is a new disease in Slovenia, which was first recorded in the year 1989 in the western and south-western parts of Slovenia on peaches, apricots and plums of a Chinese Japanese origin. However, the European stone fruit disease was observed to be constantly progressing. Although the apple proliferation disease is common in Slovenia, its presence is estimated to remain as low as about 3% of the trees. Very little is known of the presence of pear decline disease in Slovenia. Although the occurrence of the possible vectors of the pear decline disease in Slovenia is established, very little is known of the extent of their actual presence.
