KVH male monitoring reports

18 September 2014

Over the last two weeks KVH has monitored four orchards with Chieftan males as part of an ongoing monitoring programme that has been running for the past two years. Two of the orchards are located in high altitude Te Puke, and the other two in Waihi.

All four orchards showed more secondary Psa-V symptoms during this monitoring round than observed at the same time last year. This is consistent with reports received from growers and postharvest over the last two weeks.

Levels of symptoms were higher in Waihi than Te Puke. After reviewing weather data it appears temperatures went below 0°C during nine days in Waihi; and on one day in Te Puke. This occurred between 1 June and 31 August. Both regions had a heavy rainfall event on 19-20August (30mm in Waihi and 19mm Te Puke).
