Incorporate Ridomil Gold® SL Fungicide into your Pink Rot management strategy or apply in-furrow or consider tank-mixing with Bravo® ZN, Apply two foliar applications at flowering for increased activity on Late Blight, and protection against Early Blight and Botrytis Vine Rot. Growers should follow through with a post-harvest application of a registered product targeted at Pink Rot and Tuber Blight going into storage. also useful for the control or suppression of certain diseases caused by the Oomycete class of fungi in Apples (non-bearing), Field and Greenhouse Cucumbers, Ginseng, Hops, Raspberries, Blueberries, Snap Beans, Strawberries, Tobacco, Spinach, Radish and Potatoes.
Active Ingredient:
480 g/L Metalaxyl-m in the form of a Soluble Liquid.
How It Works: (Key Strength).
Ridomil Gold® is a dual-action Fungicide:
Systemic (Metalaxyl-M):
- Moves inside plant.
- Protects new growth.
- Stops Fungal development internally.
- Contact partner (e.g. Mancozeb/Chlorothalonil/Copper).
- Protects leaf surface.
- Stops spores germinating.
Result:
- Inside + outside protection.
What It Controls:
Targets oomycete diseases (VERY important distinction):
- Downy Mildew (Grapes, Onions, Vegetables).
- Late Blight (Potatoes, Tomatoes).
- Phytophthora (Root Rots, Crown Rots, Cankers).
- Pythium (Damping-off).
This is not a general Fungicide — it’s highly specialised.

- Vegetables (Potatoes, Tomatoes, Cucurbits).
- Grapes (Downy Mildew).
- Tree Crops (Phytophthora).
- Nurseries / Seedlings (Soil Diseases).
Application Principles:
- Apply preventatively or very early infection Repeat every 10–14 days if pressure remains, Limit to ~2–4 applications per season.
Critical Point:
- Works best before disease gets established.
Resistance Management: (VERY important).
- Group 4 = high resistance risk.
Rules:
- Avoid repeated solo use.
- Always mix/rotate with contact Fungicides (Mancozeb, Copper, etc).
- Limit number of sprays per season.
- Overuse = rapid resistance loss (common globally).
Strengths vs Weaknesses:
Strengths:
- Excellent on Phytophthora / Downy Mildew.
- Systemic movement (protects new growth).
