Pospiviroid positives detected by real time RT-PCR (TaqMan) are tested by RT-PCR and sequencing to try to identify and confirm the pospiviroid. Identification and confirmation is not always possible due to the low level of viroid detected in seeds and the fact that RT-PCR is less sensitive that real time RT-PCR.
Please also note that the same sample of seeds from the Pospiviroid seed testing package can be used, so no requirement for any further samples to be sent to us.
When sending plant pathogens and invertebrate samples from outside England and Wales for testing please email the Crop health team (firstname.lastname@example.org) who will issue you with the relevant Letter of Authority to ensure your samples are not delayed upon entry to the UK.
