Abstrakt		More than 1100 samples of ornamentals, mostly chrysanthemum and pelargonium plants, and vegetables, among them mostly pepper and tomato but also cucurbits and Allium species, were tested for the presence of more than 23 different viruses in years 2000, 2001 and 2002 in Slovenia. In the frame of official plant protection services, phytosanitary inspectors collected most of the samples. Symptoms were compared with ELISA results. In the case of unclear results or unknown cause of disease, the samples were additionally tested with electron microscopy and test plants. In chrysanthemum plants, tospoviruses TSWV (Tomato spotted wilt virus, SLO ILA.II list), INSV (Impatiens necrotic spot virus, SLO ILA.II list) and CSNV (Chrysanthemum stem necrosis virus, EPPO alert list) were frequently found. Frequently found virus on chrysanthemum is also CVB (Chrysanthemum virus `, which is usually symptomless. Pelargonium plants are frequently infected with PFBV (Pelargonium flower break virus), sometimes also with TSWV, INSV, CMV (Cucumber mosaic virus) and PLPV (Pelargonium line pattern virus). Viruses that were found on red pepper (Capsicum annuum) and tomato (Lycopersicon esculentum) are CMV and PVY (Potato virus >7. Besides those, AMV (Alfalfa mosaic virus), TSWV and INSV were found in pepper and TMV (Tobacco mosaic virus) on tomato only. PVY was found also on Petunia. CMV infected lettuce, cucurbits and ornamental plants such as Ajuga and Aster. Besides CMV, ZYMV (Zucchini yellow mosaic vinrs) and WMV (Watermelon mosaic virus) were frequently found on cucurbits. We found tospovirus IYSV (Iris yellow spot virus, EPPO alert list) on leek and onion, which is along with the findings of CSNV a rare finding in Europe. Tospoviruses were present also on other ornamental plants such as CSNV on Gerbera, INSV on Cyclamen, etc.
Izvleček		V letih 2000, 2001 in 2002 smo testirali več kot 1100 vzorcev okrasnih rastlin, med njimi največ krizantem in pelargonij ter vrtnin, predvsem paradižnik in papriko, predstavnike bučnic in čebulnic, na več kot 23 različnih ekonomsko pomembnih virusov. Večino vzorcev so nabrali fitosanitarni inšpektorji v okviru posebnega nadzora, ki ga vr{i uradna služba za varstvo rastlin. Bolezenska znamenja na vzorcih smo primerjali z dobljenimi rezultati serološkega testa ELISA. V primeru nejasnih rezultatov, oziroma neznanega povzročitelja, smo vzorce testirali še z elektronsko mikroskopijo in testnimi rastlinami. Na rastlinah krizantem smo najpogosteje našli tospoviruse TSWV - virus pegavosti in uvelosti paradižnika (SLO ILA.II lista), INSV - virus nekrotične pegavosti vodenke (SLO ILA.II lista) in CSNV - virus stebelne nekroze krizantem (EPPO čakalna lista). Pogosto smo na krizantemah našli tudi CVB (krizantemin virus B), ki pa običajno ne povzroča bolezenskih znamenj. Pelargonije so pogosto okužene s PFBV - virus razbarvanja cvetov pelargonij, redkeje pa tudi s TSWV, INSV, CMV - virus mozaika kumar in PLPV - virus črtavosti pelargonij. Rastline paprike in paradižnika so mnogokrat okužene s CMV in PVY krompirjev virus Y. Poleg CMV in PVY pa smo na rastlinah paprike in paradižnika našli tudi AMV virus mozaika lucerne, TSWV, INSV (le na papriki) in TMV - virus mozaika tobaka (le na paradižniku). PVY smo našli tudi na surfinijah, CMV pa smo določili, poleg omenjenega, tudi na solati in bučnicah ter na okrasnih rastlinah ajuge in astre. Poleg CMV bučnice pogosto okužuje tudi ZYMV - virus rumenega mozaika bučk ter WMV - virus mozaika lubenic, o katerem smo že predhodno poročali. Na poru in čebuli smo našli tospovirus IYSV - virus rumene pegavosti irisa (EPPO čakalna lista), ki se v Evropi in v svetu izredno redko pojavlja, podobno kot CSNV. Poleg zgoraj omenjenih rastlin, smo tospoviruse našli tudi na drugih okrasnih rastlinah, npr. CSNV na gerberi, INSV na ciklami, itd.
