Common crops affected
Why it matters
It spreads fast in crowded canopies, cuts photosynthesis and yield, and downgrades fruit; in high-value crops it can be economically serious. Early and preventative action wins.
When to act
Protect from early shoot growth through bunch closure; the critical window is pre-bloom to berry set.
What to look for
- Dusty white colonies on leaves, shoots and clusters
- Puckered, distorted young leaves
- Dull, webbed patches on berries; skin cracking as they expand
- Off-flavours and rot entry where berries split
How to manage it
- Open the canopy for airflow; avoid excess nitrogen.
- Remove affected leaves.
- Apply Mildew Control (1:2,000) at first sign and preventatively on susceptible crops.
