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 through veg and early flower; scout dense zones and act on first spotting.
What to look for
- White powdery spots on fan leaves, spreading to bud sites
- Musty growth in dense canopy zones
- Downgraded, unsaleable flower
- Fast room-wide spread under high humidity
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.
