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 (%) | Range of yield loss for different levels of blackspot risk (%) |
|---|---|---|
| Low | 60 – 100 | 2 - 15 |
| Medium | 30 - 59 | 20 - 35 |
| High | 0 - 29 | 25 - 50 |
