New Whangarei Psa-positive orchard

08 August 2019

A further Psa result has been confirmed on a Whangarei orchard this week bringing the total positives in this region to six.

Red exudate was observed on one G3 trunk girdle on an orchard which is in close proximity to other positive orchards in the region.

Growers in this and other regions with Not Detected orchards should be monitoring regularly to identify any symptoms. Look for cane dieback and check carefully around any wounds (i.e. grafts, girdles). Young plants are generally more at risk, as are stressed vines or those in cold, damp areas.

There have been a number of high-risk weather events recently and we are coming up to the spring infection period, so it is important to maintain a good protectant spray programme and good hygiene practices.
