The colours on the risk image have been scaled to show how the severity of Septoria in 2016 is expected to deviate from the observed 10 year average (2006 - 2015) severity on leaf 2. Zones with a green to blue colour are predicted to have a lower severity than the 10 year average, those with a yellow through to red colour are predicted to be above the 10 year average.
By rolling over a particular region you can see the historic observed average severity, the forecast deviation for 2016 and how many weather stations have been used to generate the prediction.
- After the relatively quiet year seen in 2015, the disease risk is forecast to be moderately more severe across most areas in 2016.
- The extended winter conditions experienced so far in 2016 will have delayed the development of Septoria inoculum present in crops.
- The rainfall during mid-April to June will have substantial effect on Septoria development as the season progresses. CropMonitor will issue an update to the forecast, if required, in mid May.
