You may notice weather station changes for some locations. This is to ensure that the weather data being used is the most accurate available for the area and uses open DPIRD and BOM weather stations whenever possible. In some locations, a suitable weather station may not be available and so we may use interpolated weather data, which uses data from surrounding stations to create reasonable values for missing weather data.
Sowing time can depend on a range of factors and it is recommended to consult an agronomist to determine the optimal sowing window for your situation.

Key to blackspot severity scores
The aim is to delay sowing of field pea crops, where agronomically possible, until the majority of blackspot spores (approximately 60%) have been released prior to the crop emergence. This strategy reduces yield losses from blackspot.
Blackspot risk | Spores released (%) | Yield loss for different levels of blackspot risk scenarios (%) |
Low | 60 - 100 | 2 - 15 |
Medium | 30 - 59 | 20 - 35 |
High | 0 - 29 | 25 - 50 |
