Tobacco ringspot virus is eradicated from the Netherlands

This update pest report concerns an update of the pest status in the Netherlands following multi-annual surveys. The latest finding of TRSV was reported in September 2019 in plants for planting of Ajuga reptans as part of a specific survey whereby asymptomatic plants of 30 locations have been sampled and tested. This survey specifically targeted Ajuga, following two positive testing records (non-official) of two lots during 2018, of which one originated in a third country and the other in the Netherlands.

For TRSV this concerned the first official finding in Ajuga reptans. Since 2000, other findings of TRSV were recorded in plants for planting of Bacopa (2000, 2006), Celosia (2008), Portulaca (2000, 2006, 2007), Hemerocallis (2006, 2018), Iris ensata (2006), Iris
siberica (2006), Iris germanica (pest report September 2017 and September 2019) and Phlox subulata (2010, and pest report March 2018). At the beginning of 2020 TRSV was also reported by an operator in Rosmarinus plants originating in a third country. These
plants were destroyed.

On the basis of the multitude of findings in the Netherlands and elsewhere in the EU, it is presumed the virus is wider spread in the EU than currently known, both in terms of geographic distribution as well as in terms of host plants. In case of future findings, measures will be taken for infected lots (destruction) to prevent the spread of the virus. Following a finding, the Netherlands will no longer test all other
(potential) hostplants at a company. Specific TRSV surveys will only be carried out in case of new findings.
