Orchard sites that experienced colder autumn and winter periods are reporting a higher incidence of Psa-V symptoms this spring.

Wanganui, Waikato, and Waihi sites, which experienced frosts shortly after harvest and also had a number of frost events with temperatures below zero for extended periods, are reporting increased levels of symptoms in Hayward males including Chieftan.

Late growth which was not fully mature, or growth that was damaged through autumn storms, is showing higher incidence of secondary symptoms.

Growers are recommended to particularly focus on colder areas of their orchard when monitoring to determine individual orchard impacts.
