Movement restrictions placed on kiwifruit nursery stock

Friday 3 June 2011

The Ministry of Agriculture and Forestry (MAF) has placed restrictions around the movement of kiwifruit nursery stock (including living kiwifruit plants, rootstock and budwood), as part of the ongoing programme to contain the spread of the kiwifruit vine bacterial disease Pseudomonas syringae pv actinidiae (Psa).

The controls prohibit the movement of any kiwifruit nursery stock out of a designated zone known as a controlled area. This controlled area surrounds the Te Puke township and includes the areas where properties infected with the more virulent type of Psa (Psa-V) are located, as well as a surrounding buffer zone.

MAF Response Manager David Yard says the controlled area notice has been issued to help prevent spread of this virulent type of Psa to growing areas that are so far free from infection.

“We have established that plant material and rootstock may be able to carry Psa and relocate it to uninfected orchards. For this reason, we need to ensure that plant material from the area known as the priority zone, or from the buffer area around it, is not moved to Psa-free areas,” Mr Yard says.

This controlled area notice does not restrict the movement of either fruit itself or kiwifruit pollen.

Nurseries within the controlled area will still be able to sell their product.

Mr Yard says Kiwifruit Vine Health (KVH) the industry organisation leading the kiwifruit industry response to Psa, will purchase and destroy any stock from within the priority zone where Psa has been detected. Any remaining stock from nurseries in the controlled area will be purchased by KVH at the end of the season.

The controlled area takes in the district surrounding Te Puke township in the Bay of Plenty bordered in the North by the sea, in the West by Domain Road and the Papamoa Hills, in the South by the highest points on Number 3, Number 2, Te Matai, Maungarangi, Ridge, Maniatutu, Pongakawa Bush Roads, and the highest point on State Highway 33 and the Pongakawa Valley and the Rotoehu Forest and in the East by Pikowai Road.

As part of a community education campaign to reduce the risk of the kiwifruit vine killing disease Psa spreading to other regions, KVH is placing road signs carrying the message: “Prevent Psa Disease on Kiwifruit Orchards: Control Plant Movement”, on key roads leading into the wider Te Puke region. They will be a visible reminder to the kiwifruit industry and the wider surrounding community, of the need to control the movement of kiwifruit plant material out of the region.

A map of the Controlled Area is available from the MAF website.

About Psa

  • Psa is a bacterial vine disease that carries no risks associated with human or animal health, and does not affect plants other than kiwifruit vines.
  • As of 1 June 2011, a total of 239 orchards have been confirmed with Psa in various regions throughout New Zealand.
  • The majority of orchards identified with Psa are in the greater Te Puke region (199 or 83%).
  • 122 orchards have been confirmed with Psa-V, the majority of which are in the greater Te Puke region, with two preliminary results outside the Te Puke region, which are yet to be confirmed.
  • Psa affected orchards have also been identified in Franklin, Hawke’s Bay, Katikati, Poverty Bay, Tauranga, Whakatane/Edgecumbe, Waikato, Golden Bay, Horowhenua and Motueka.
  • The majority of Psa symptoms identified are considered primary symptoms – leaf spotting. A Psa Priority Zone has been established near Te Puke, surrounding an area of more severe infection.
  • As of 1 June 2011, 747 hectares have been affected by Psa.
  • All growers, across all regions, are strongly encouraged to adhere to orchard hygiene and monitoring protocols.
