“…SMYEV is reported from all five continents ( Figure 1). In the USA, SMYEV was detected in all production areas at rates varying between 4 and 68 % (11.5 % California, 53 % Pacific North-west, 4 % Midwest, 39 % South-east, 68 % Northeast) (Martin and Tzanetakis, 2013) In recent years, the virus has also been reported in Korea (Cho et al, 2011), Argentina (Conci et al, 2009) In total, 818 samples were analysed throughout Belgium. The pest was found on strawberry in the provinces of Antwerp (three locations, 2012), Limburg (two locations, 2012), East-Flanders (one location in 2011 and in 2012, also positive for SLRV in 2012) and West Flanders (two locations in 2011, both negative for SMYEV in 2012 but one positive for SLRV in 2012).…”

“…Despite SMYEV variability, efficient detection assays are available. SMYEV can be readily detected, using either enzyme-linked immunoassay (ELISA)-based serological methods (Conci et al, 2009;Jelkmann et al, 1990;Kaden-Kreuziger et al, 1995) or polymerase chain reaction (PCR)-based molecular detection assays (Thompson et al, 2003;Cai et al, 2009). SMYEV can also be detected by biological indexing in susceptible indicator plants (Harris and King, 1942;Frazier, 1975), a technique that was historically used to differentiate the SMYE disease from other diseases such as the pseudo mild yellow edge disease, which is now known to be associated with a Carlavirus (Yoshikawa and Inoyue, 1986).…”

Scientific Opinion on the risk to plant health posed by Strawberry mild yellow edge virus to the EU territory with the identification and evaluation of risk reduction options

The Panel on Plant Health assessed the risk to plant health of Strawberry mild yellow edge virus (SMYEV) for the European Union (EU) territory, and evaluated the current EU legislation and possible risk reduction options. This virus is widely distributed both within and outside Europe and the same applies to its main vector, the strawberry aphid, Chaetosiphon fragaefolii. At-risk hosts (Fragaria spp.) occur widely in Europe. Plants for planting were identified as the most significant entry pathway and the probability of entry is rated as unlikely to moderately likely with high uncertainty. The probability of establishment is rated very likely with low uncertainty. The probability of local spread by natural means is moderately likely to likely, with medium uncertainty, whereas that of human-assisted long-distance spread is unlikely, with medium uncertainty. The potential consequences are rated as minimal to minor with medium uncertainty. Prohibition and restricting import or intra-EU trade to certified materials or to materials originating from pest-free areas or pest-free places of production are the options with highest effectiveness against the risks of introduction or against the risks of further spread. Prohibition and certification are also among the options of high or very high feasibility. In addition, it should be noted that the combination of options (cultural practices, certification, exclusion conditions, tolerant varieties) has an overall high to very high level of effectiveness and feasibility. The current legislation has few weaknesses: the reliance on inefficient visual inspection as well as the exceptions or derogations offered to some countries in which SMYEV is present. If the current legislation were removed, no major consequences would be expected unless the industry simultaneously ceased its widely adopted certification activity, which seems unlikely given the potential consequences. 3 Acknowledgement: The Panel wishes to thank the members of the Working Group on strawberry viruses (SCV and SMYEV) pest risk assessment: Thierry Candresse and Stephan Winter for the preparatory work on this scientific opinion and the hearing expert: Wilhelm Jelkmann, and EFSA staff: Virág Kertész for the support provided to this scientific opinion. Pest risk assessment of Strawberry mild yellow edge virus EFSA Journal 2014;12(4):3629 2 SUMMARYFollowing a request from the European Commission (EC), the EFSA Panel on Plant Health (PLH) was asked to deliver a scientific opinion on the pest risk of Strawberry mild yellow edge virus (SMYEV) for the European Union (EU) territory and to identify risk reduction options and evaluate their effectiveness in reducing the risk to plant health posed by the organism. In particular, the Panel was asked to provide an opinion on the effectiveness of the current EU requirements against this organism, which are laid down in Council Directive 2000/29/EC, in reducing the risk of introduction of the pest into, and its spread within, the EU territory.The Panel conducted the pest risk as...

“…production, given the vegetative propagation of this specie (Martin & Tzanetakis, 2006;Bhagwat et al, 2016). Four aphid-transmitted viruses have been detected in strawberry crops in Argentina: Strawberry mild yellow edge virus (SMYEV), Strawberry mottle virus (SMoV), Strawberry crinkle virus (SCV), and Strawberry polerovirus 1 in simple and multiple infections (Nome & Yossen, 1980;Conci et al, 2009;Perotto et al, 2014;Luciani et al, 2016). The aphid-transmitted viruses are considered of utmost economic importance in almost all strawberry production areas around the world (Converse, 1987;Martin & Spiegel, 1998a).…”

The vegetative propagation of strawberries favors transmission of systemic pathogens, such as viruses, which are one of the main yield-limiting factors for this crop. More than 20 viruses have been described as infecting this species; one of the most frequent is the Strawberry mottle virus (SMoV), which is responsible for significant economic losses. SMoV is usually detected by reverse transcription polymerase chain reaction (RT-PCR), given that serum is not available for serological tests. In this study, a non-radioactive molecular probe was developed for SMoV detection. The cDNA was synthesized by RT-PCR using specific primers designed from the 3'UTR region of the viral genome. The cloned cDNA segment was labeled and used as a probe. Six RNA extraction protocols were evaluated, and the modified cetyltrimethylammonium bromide (CTAB) method showed the highest sensitivity level. Leaves at different phenological stages and petioles were evaluated; the highest reaction was observed in old leaves and in petioles.
