A further observation report on infected male vines shows how the effects of a colder site, Psa-V infection history, lower input Psa-V strategies (cultural management and protective spray programmes) and less-tolerant varieties can result in very compromised pollination potential.

Ongoing Psa-V management is necessary on all orchards and more challenging spring conditions clearly illustrate the re-emergence of Psa-V on vulnerable sites.

Monitoring and removal of infected material through spring remains a primary tool in reducing risk of Psa-V inoculum building and compromising orchard productivity.
