Symptoms not always what they seem

Three recent reports of symptoms appearing to be Psa-V (red exudate) have received ‘Not Detected’ results following testing.

The samples from three different varieties in three different regions have been sent to MPI for further analysis. Testing is in progress. While no other strains of Psa have been identified so far, a fungi commonly associated with wounding has been identified on one sample.

We know wounds are a pathway for Psa-V to enter, and this could also be the case for other diseases. Therefore growers are advised to remain vigilant with monitoring and applying protectant sprays and to continue to protect vines by sealing any wounds.


KVH investigates reports of unusual symptoms to identify and manage any biosecurity risks.
