Movement of plant material, including budwood, poses one of the greatest risks of spreading Psa-V within and between orchards and regions.
Individuals and organisations supplying budwood are required to register with KVH here or ph 0800 665 825. All budwood suppliers must follow the Budwood Movement Protocols below. This includes having a Psa-V Budwood Risk Management Plan in place.
Ensure strict hygiene protocols are followed when grafting. Ideally, all grafting tools must be cleaned and disinfected between every vine to avoid the risk of contamination and/or disease transfer between scions and stumps.
Good hygiene practice may limit or prevent the spread of Psa-V from vine to vine, and between orchards. Refer to KVH’s one-page summaries on grafting yygiene for best-practice guidelines. www.kvh.org.nz/seasonal_advice.
