AB  - In Europe, the cultivation of sugar beet faces significant challenges due to the emergence of basses richesses syndrome (SBR) and rubbery taproot disease (RTD) which are associated with fastidious bacteria Candidatus Arsenophonus phytopathogenicus and Candidatus Phytoplasma solani, respectively. A comprehensive study conducted from 2018 to 2022 aimed to elucidate the prevalence and distribution of these pathogens in sugar beet in central Europe, focusing on the Pannonian Plain (particularly Serbia and Slovakia where RTD has been present in epidemic scales) and Germany.

AB  - Reptalus quinquecostatus (Dufour, 1833) is one of several species from the planthopper family Cixiidae that are known as vectors of plant pathogenic bacteria that can cause severe agroeconomic losses. Records of this species in Serbia by Horváth, Tanasijević and Janković refer to Oliarus quinquecostatus Dufour, 1883 [sic]. The species was described as inhabiting meadows and grasslands and reported as caught on Salix sp., Ulmus sp., Quercus sp., and Malva sylvestris. Modern-day molecular identification of species, i.e. sequencing of cytochrome oxidase subunit 1 (COI) gene, revealed the presence of R. quinquecostatus nymphs in the rhizosphere of Koeleria macrantha (Poaceae family) in eastern Serbia. This cixiid has been found in Serbia on various crops affected by ‘Candidatus Phytoplasma solani’: corn, grapevine, potato, and most recently, sugar beet. The occurrence on sugar beet was first reported in 2020 in northern Serbia when its population was aggregated on a boundary strip with several weeds: Convolvulus arvensis, Chenopodium album, Amaranthus retroflexus, Ambrosia artemisiifolia etc. During the 2021–2022 survey, the presence of R. quinquecostatus on sugar beet was confirmed on other localities in Serbia. Moreover, its populations were recorded on parsnip, tobacco and corn. Prunus spinosa and Crataegus sp. in microhabitats permeating arable land were also found preferable for R. quinquecostatus adults. Its several populations on different hosts were repeatedly sampled in June–July 2022. Populations on P. spinosa and Crataegus sp. were highly abundant and infected with ‘Ca. P. solani’, whereas in the agroecosystems, R. quinquecostatus is present in mixed population with R. panzeri, displaying minor precedence in the emergence of adults. Data on R. quinquecostatus plant preferences in Serbia support the polyphagy that has been previously reported throughout Europe. Since the genus Reptalus Emeljanov, 1971 has recently undergone nomenclatural and taxonomic revision, the use of the valid species name and proper morphological species identification, which in some cases should be supplemented with molecular tools, are crucial in biodiversity and insect pest research.

AB  - Rubbery taproot disease (RTD) appearance and symptoms have been described in Bulgaria, Romania and Serbia more than 60 years ago. At that time disease symptoms were associated with abiotic factors (drought). Latest researches about RTD reveal that Candidatus Phytoplasma solani is the causing agent of the disease and the presence of the disease also in Croatia, Hungary and Slovakia. After declining of the plants, roots are prone to rotting due to the activity of saprobes. Symptoms and the progress of the disease differ depending on climatic conditions. The first symptoms usually start appearing by the end of July and beginning of August. In wet years yellowing of the oldest leaves and relatively slow progress of the beet deterioration can be observed on the edges of sugar beet fields. In dry years, because of the drought, oldest leaves are being discarded very fast and the first visible symptom of the disease is a loss of turgor in young leaves during the hottest part of the day. If dry conditions continue, all leaves become necrotic, which leads to the complete decline of the plant. Taproots of diseased plants wilt, become rubbery, and stay without any rot symptoms until complete plant decline. A yield loss in the same beet field varies spatially and is usually aggregated toward the edges. Epidemiological studies of the disease are in progress.

AB  - Pojava bolesti gumoze šećerne repe je primećena u Srbiji prvi put u Banatu i Bačkoj šezdesetih godina prošlog veka. Koren obolelih biljaka ispoljava različit stepen gumoze uz uvenuće listova. Iako je koren zaraženih repa inicijalno bez truleži, nakon uvenuća ili vađenja biljke, podložan je napadu saprofita. Simptomi gumoze repe su zabeleženi takođe u Bugarskoj i Rumuniji i primarno su dovođeni u vezu sa sušom. Narušene fizičke karakteristike korena obolele šećerne repe mogu dovesti do odbacivanja kompletnog prinosa od strane šećerana. Nakon perioda epidemijske pojave, bolest je bila sporadično prisutna. U periodu 2018-2020 godine gumoza je zabeležena u svim područjima gajenja šećerne repe u Srbiji, u epidemijskoj ili neepidemijskoj razmeri, ukazujući na periodičnu pojavu oboljenja što je karakteristično za bolesti izazvane stolbur fitoplazmom (‘Candidatus Phytoplasma solani’). Epidemijska pojava gumoze repe je u ovom periodu zabeležena i u Slovačkoj, a sporadična u Mađarskoj i Hrvatskoj. Šećerne repe sa simptomima gumoze sakupljene u navedenim zemljama su testirane na prisustvo stolbur fitoplazme primenom molekularnih metoda. Svi detektovani izolati fitoplazme su dalje genotipizirani na tri epidemiološki informativna gena tuf, stamp i vmp1. Prisustvo fitopatogene bakterije ‘Ca. Arsenophonus phytopathogenicus’, uzrokovača bolesti repe “basses richesses” (SBR) u Francuskoj, Nemačkoj i Švajcarskoj, takođe je testirano i nije utvrđeno u analiziranim uzorcima. Etiologija gumoze šećerne repe je rasvetljena u Novom Sadu (Rimskim Šančevima) gde je utvrđena asocijacija stolbur fitoplazme i tipičnih simptoma ove biljne bolesti.
