Growers who find Psa for the first time on their property are required to advise KVH within 48 hours of identification. KVH will pay for lab testing in Exclusion regions and 'Not Detected' orchards in Containment regions only. Growers organising their own testing are reminded Hill Laboratories run testing for Psa once a week – every Wednesday. However, for urgent sampling, they can turn around a rapid test within 48 hours if need be. There is an additional cost to do this. Click here for KVH's sampling and testing page.
