Common crops affected
Why it matters
It moves fast during warm wet bloom and overwinters in cankers. It is bacterial and cannot be cured once tissue is infected — management is prevention and pruning, with protective inputs in a supporting role.
When it appears
Warm, wet weather during bloom.
How to identify it
- Blackened, scorched-looking shoots and blossoms that stay attached
- Shoot tips bent into a shepherd's crook
- Bacterial ooze in humid weather; dark cankers
How to manage it
- Prune out infected wood well below symptoms; disinfect tools.
- Remove overwintering cankers; avoid excess nitrogen.
- Use Spore Control as a protective, supporting input during the bloom window — not a cure.

Integrated management. This is a bacterial / no-cure or indirect problem — Vegalab products play a supporting role in an integrated program (plant health, prevention, protection) and are not a cure. Combine with sanitation, clean material, rotation and cultural controls.
