Sovrin Flo® is a Morpholine Fungicide for the control of Downy Mildew on Grapes, Lettuce and Onions, and Early and Late Blight on Potatoes.
Active Ingredient:
Contains 500g/litre Dimethomorph in the form of a suspension concentrate.
What It Controls:
Sovrin Flo® is specifically designed for Oomycete (“Water Mould”) Diseases.
Downy Mildew:
– Grapes.
– Lettuce.
– Onions.
Late Blight:
– Potatoes.
Early Blight:
– Potatoes – Suppression.
– Very similar disease space to Ridomil®-type products, but with a different chemistry.
How It Works: (Key Strength).
– Locally systemic (moves within treated tissue).
– Strong anti-sporulant activity (stops disease spreading).
Provides Both:
– Preventative protection.
– Early curative action.
Key Point:
– Not just protective — it can stop early infections developing.
Where It’s Used:
– Grapes.
– Lettuce.
– Onions.
– Potatoes.
Especially Valuable In:
– Vegetable Systems.
– Viticulture (Downy Mildew).
Application Principles:
Apply:
– Preventatively or at first sign of disease.
Use:
– High water volumes for good coverage (≥200 L/ha typical).
Like Most Downy Mildew Products:
– Timing is critical → don’t wait until heavy infection.
Resistance Management:
– Dimethomorph® = single-site fungicide → resistance risk.
Label/Technical Guidance:
– Rotate with other Fungicide Groups.
– Use in programmes, not repeated solo applications.
Often Alternated With:
– Mancozeb® mixes.
– Copper®.
– Other Systemic Fungicides.
Safety & Environmental:
– May cause organ damage with long-term exposure.
– Toxic to aquatic life (long lasting).
Precautions:
– Avoid spray drift and runoff.
– Wear PPE.
– Do not contaminate waterways.
– Simple way to think about it Ridomil® = strong systemic + protectant mix.
– Sovrin Flo® = more targeted anti-sporulant + early curative.
Both Hit Similar Diseases, But:
– Sovrin Flo® is often used to tighten control and resistance rotation.
Bottom Line:
– Sovrin Flo® = Specialist Downy Mildew / Blight Fungicide.
Strengths:
– Anti-sporulant activity.
– Early curative effect.
– Good programme fit.
Limitations:
– Not for Botrytis or Powdery Mildew.
– Needs rotation to avoid resistance.
Caution:
Must be used strictly according to label directions.
Available in 5L.
