Psa symptoms on Arguta
20 October 2016
KVH has received reports of Psa symptoms from three Arguta orchards this week.
Leaf spot, blackened leaves and shoot collapse has been observed on two varieties and test results from Hills confirmed samples as Psa positive.
Arguta growers are recommended to monitor their blocks and contact KVH if Psa-like symptoms are seen, particularly on Psa-V undetected sites. This level of symptom expression is higher than seen in previous seasons.
