NAME OF THE ORGANISM: Nepovirus rubi (raspberry ringspot virus) (RPRSV0)

Yes

In general very few reports on nepoviruses of berries can be found, most references dating before 1995.
Martin & Tzanetakis (2006) reported that raspberry ringspot virus on Fragaria vesca indicator clones initially show a yellow blotching, but the symptoms fade. In some strawberry cultivars, leaves develop yellow blotching, ring spots, crinkling, stunting, and eventually plants may die.
The incidence of virus-infected plants generally remains localised because of limited spread by the nematode vectors (EFSA PLH, 2013).

EFSA (2013) refers to Murant & Lister (1987) as part of a general statement on the impact of nepoviruses on Fragaria and Rubus. On checking, this article only relates specifically to RRV and TBRV alone or as a mixed infection on strawberry, and even then it states "with large outbreaks economic loss may...be considerable", and then proceeds to describe symptoms rather than economic impacts in sensu stricto.

Cultivation practices strongly limit this potential for impact. According to EFSA (2013), the most significant factor is certainly that efficient voluntary certification schemes for strawberry and raspberry are in place and ensure that healthy planting materials are used by growers. Additional factors contributing to a reduction of the impact are (1) the significantly shorter cycles of modern strawberry and raspberry cultivation practices (one to two seasons), which limit the potential for disease build-up, (2) the increasingly frequent use of soil-less cultivation practices, which limit the impact of nematode vectors and (3) the availability of resistant or tolerant cultivars of raspberry. As a consequence of the conjunction of these various factors, these nematode-transmitted viruses are found only occasionally in these crops and the diseases they cause are considered of minor significance by growers as illustrated during the hearing of industry experts. Current impact of these viruses (under existing regulatory framework) in Fragaria, Rubus and Ribes hosts was considered by EFSA (2013) to be minimal to minor, with low uncertainty.
The Fruit SEWG commented that voluntary certification schemes are not widely used in all EU countries. For instance, in Spain, between 60-70% of the material is certified in Fragaria, and practically nothing in Rubus and Ribes (certification started in 2024). Consequently, in absence of evidence for relevant symptoms and economic impact in the last decades, the Fruit SEWG concluded that economic impact should be considered as acceptable.
