Challenging spring conditions
3 October 2019

The hail event in the Hawkes Bay this week is a reminder of the fickleness of spring weather, with extreme events like this increasing Psa risk through the creation of wounds via leaf shatter.

Affected growers should apply a Psa protectant as soon possible, and on sites where Psa risk is higher bactericides should be considered. If growers are planning to use bio stimulants to help recover vines a reminder to ensure a 7-day window is maintained between these and copper. Actigard may also be applied once vines start to recover.

Looking ahead to next week, the Psa Risk Model again predicts moderate to high-risk weather in many areas particularly in the Waikato and Bay of Plenty.
