Common crops affected
Why it matters
It spreads from dying or wounded tissue and releases huge spore loads, so one infected fruit can rot a whole batch; sanitation and early protection are key.
When to act
Protect from bunch closure to harvest, tightening cover in wet spells.
What to look for
- Brown, softening berries with gray sporulation
- Rot spreading through tight clusters
- Split berries as entry points
- Off-characters in must from infected fruit
How to manage it
- Remove dead and infected tissue; improve airflow and lower humidity.
- Handle fruit gently; cool quickly after harvest.
- Apply Spore Control (1:1,000) through cool, damp periods.
Recommended Vegalab program
Spore Control — adherent encapsulated cover that resists wash-off on clusters.
| Role | Product | Use |
|---|---|---|
| Primary control | Spore Control | Thymol; reduces inoculum on flowers & fruit |
| Firmness support | Rigid Boost | Firmer tissue resists invasion |
| Plant resilience | Armour Boost | Resilient tissue |
