PSA found on third orchard in Waikato

2:01 pm on 11 October 2012

A further case of the kiwifruit vine killing disease PSA has been confirmed in the Waikato region, outside the existing control zone.

The disease was found in a single 16A gold variety vine on an organic orchard in the Lake Karapiro area.

Kiwifruit Vine Health Waikato co-ordinator Richard Glenn says the infected vine has been removed and the grower is continuing the spraying programme he had already started.

It's the third Waikato orchard where PSA has been found.

In August, the disease was discovered on two orchards in the Te Awamutu area. The gold vines have been removed from those and the growers are treating the green variety vines.

Mr Glenn says a new 10 kilometre radius control zone has been established in the Karapiro area, where a lot of gold kiwifruit is grown, with restrictions on the movement of plant material and strict orchard hygiene practices in force.

The new case has doubled the area under movement control in the region.

PSA has also spread to a new site near Clevedon in the Franklin district south of Auckland.
