Detailed records of virus diseases of small fruits
In the ISHS Newsletter on virus disease of small fruit crops, the following detailed occurrences (no new geographical record) were reported.
Arabis mosaic nepovirus (EU Annex II/A2) was found causing a severe disease in black currant crops in southern Ireland.
Tomato black ring nepovirus (EU Annex II/A2) was detected for the first time in red currant in England (GB).
In Czech Republic, the occurrence of arabis mosaic nepovirus (EU Annex II/A2), raspberry ringspot nepovirus, tomato black ring nepovirus (EU Annex II/A2) and strawberry latent ringspot nepovirus (EU Annex II/A2) was studied on raspberry and blackberry. 56 samples of cultivated and 85 samples of wild raspberries, as well as 10 samples of wild blackberries were tested by DAS-ELISA. Out of the 158 tested samples, 28 (18.7 %) were found infected with at least one nepovirus. It is noted that the results obtained gave the first evidence of the occurrence of arabis mosaic, raspberry ringspot, tomato black ring and strawberry latent ringspot nepoviruses in cultivated raspberries, and the first evidence of raspberry ringspot nepovirus on raspberries and blackberries in Czech Republic.
