Managing male vines well is a key part of safeguarding orchards against Psa infection and future-proofing pollen supply for the orchard. Where needed, more tolerant male varieties should be grafted in and male pruning should be well supervised.

• Remove obviously Psa infected canes and wood
• Make the structural cuts to help promote spur growth and provide a flat, open canopy
• Seal any large wounds with suitable sealant.
• Maintain a gap between male and female vines
• Carry out pruning in dry weather
• Always maintain good tool hygiene to avoid infection transfer
• Follow pruning rounds with a Psa-V protectant spray
