Waikato regional report
Many Waikato growers reported high levels of Psa-V symptoms in spring 2015 and in some blocks, cutting out due to infection continues. Sites that experienced multiple frosts below -2 degrees through winter and/or autumn were hit particularly hard. Due to the harsh winter, Psa-V symptoms were more severe and widespread than in 2014.
KVH visited Hayward and Gold3 Waikato orchards a number of times through 2014-15 to work with growers and observe Psa-V progression and management practices.
