Australia: Seeka warns of possible Psa detection in Victoria kiwifruit orchard

October 02 , 2018

New Zealand-based kiwifruit grower Seeka has warned that it may have found the vine disease in an orchard it is developing in the Australian territory of Victoria.

The company has notified Agriculture Victoria of unusual bacterial symptoms and is removing suspicious plant material pending further test results.

While the presence of the disease has not been confirmed, Seeka says the symptoms are consistent with Psa, which devastated the New Zealand kiwifruit industry after it entered the country nearly a decade ago.

The affected plants are in a non-producing part of the orchard at Shepparton.

“As part of our preventative measures, Seeka has removed the grafted canopy from 4.5 hectares of the two-year-old vines, with the remainder under watch,” it says.

“The Hayward variety in production does not appear to be affected and our experience in New Zealand is that Hayward can tolerate PSA.”

Psa, found in New Zealand in 2010, is estimated to have infected 80 percent of the country’s kiwifruit orchards nationwide and cost the industry up to NZ$1 billion in lost exports.

Seeka shares fell 10 cents to NZ$6. They are down about 8% this year.

Australia, where Seeka also grows nashi and pears, contributed about 9% of the firm’s NZ$29.4 million of operating earnings in the six months ended June 30. The company is planning significant expansion there from 2021.

The Te Puke-based company said it doesn’t expect any material financial impact on the current year’s business and left guidance unchanged. It previously forecast full-year net profit of NZ$6.5 million to NZ$7.2 million, an increase of at least 12%.

Seeka has about 250 hectares of orchards in Australia. About 154 hectares of that is in kiwifruit, of which 93 hectares are the green Hayward variety 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 ago.
