Make the most of the Psa Risk Model
13 December 2018

A reminder to keep watching the Psa Risk Model as pockets of moderate and high-risk weather continue for many regions. Once day/night temperatures average 20 oC or higher, for periods of a week or more, Psa infection risk falls away but, in the meantime, growers should use the model to assist with planning spray and orchard activities.

Additional features have recently been added to the model display to help interpretation, including a Graphs Guide (in the list to the right of the options box) that covers the basics of graph features and plots to assist users. A Wet Hours column has also been added to the data table to help provide some insight into the possible reason for days with low-risk (R index).

Please note that we have been advised access to the Waihi weather station has been temporarily disabled while data access issues are improved. We apologise for this inconvenience which we hope will be resolved in the New Year.
