Seeka notifies Australian kiwifruit orchard symptoms

Seeka [NZX:SEK] advises that, as a result of its on orchard monitoring system in Australia, it has
notified Agriculture Victoria of unusual bacterial related symptoms in the orchards under
development. The symptoms are consistent with the PSA disease (pseudomonas syringae pv
actinidiae) – although the presence of this disease is still to be positively confirmed. We have
advised Agriculture Victoria, who are now moving to take samples for analysis.
In total, Seeka has 154 hectares of kiwifruit in Australia of which 93 hectares are the Hayward variety
[green] and in production. The remaining 61 hectares are in development, with 47 hectares planted
in root stock and ungrafted, and 14 hectares grafted two years go. As part of our preventative
measures, Seeka has removed the grafted canopy from 4.5 hectares of the 2-year-old vines, with the
remainder under watch. The Hayward variety in production does not appear to be affected and our
experience in New Zealand is that Hayward can tolerate PSA.
The detection is in the non-producing part of the orchard, and normal hygiene and response
protocols have been put in place. Seeka is removing suspicious plant material, and is re-evaluating
the varietal mix to be grafted into the orchards under development and is likely to have a greater
focus on Hayward, which is less effected by PSA, if that is the disease. PSA is not expected to be a
significant problem in Australia given the hot summer climate, and is more likely to express
symptoms in the spring.
Seeka does not expect any material financial impact on the current year as a result of the detection
and the company’s guidance remains unchanged.
Seeka will update the market on any material change or confirmation.
