FMC Cosuit® Fungicide (Copper Hydroxide 61.41% WG)
The Ultimate Dual-Action Shield Against Fungal and Bacterial Diseases
FMC Cosuit® is a premium, broad-spectrum contact fungicide and bactericide designed for modern agriculture. Unlike older copper formulations, Cosuit® utilizes advanced Wettable Granule (WG) technology to deliver higher bio-available copper with a smaller particle size. This ensures superior leaf coverage, excellent rainfastness, and powerful protection against tough diseases like Downy Mildew and Bacterial Blights.
Best For: Farmers seeking a high-quality solution for Grapes, Paddy, Chillies, and Vegetables to manage complex disease outbreaks during high-humidity seasons.
Why Choose This Product? Key Benefits
- ⏱️Rapid Contact Action: Releases copper ions immediately upon contact with moisture, killing fungal spores and bacteria before they can penetrate the leaf.
- ?️Dual Protection (Fungicide + Bactericide): A unique "One-Shot" solution that controls both fungal infections (like Mildews) and bacterial attacks (like Xanthomonas) simultaneously.
- ⏳Superior Resistance Management: Acts on multiple sites within the pathogen cell (Multi-Site Action), making it nearly impossible for pests to develop resistance.
- ?️Excellent Rainfastness: The advanced WG formulation sticks better to the leaf surface, resisting wash-off during monsoons better than generic powders.
- ?Crop Safety & Dust-Free: Designed to dissolve fully without clogging nozzles. The dust-free granules are safer for the operator to handle than loose powders.

How It Works: Mode of Action
FMC Cosuit® operates as a powerful Multi-Site Inhibitor. Upon application, the granules release active Copper ions (Cu2+) in the presence of moisture.
- Cell Wall Destruction: The copper ions attack the pathogen's cell wall lipids, causing the cell contents to leak out.
- Protein Denaturation: It disrupts the enzymes and proteins essential for the fungus or bacteria to survive.
- Energy Blockade: It interferes with the respiration process, effectively starving the pathogen of energy.
Because it attacks multiple parts of the cell at once, pathogens cannot easily develop resistance to Cosuit®.
Target Crops & Pests

|---|---|
| Grapes | Downy Mildew |
| Paddy (Rice) | Bacterial Leaf Blight (BLB) |
| Tomato & Chilli | Early Blight, Bacterial Spot |
| Tea | Blister Blight |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Grapes | 200 - 250 g | 200 L | 1.25 g/L | As per Label |
| Paddy / Rice | 200 - 250 g | 150 - 200 L | 1.5 g/L | As per Label |
| Chilli / Tomato | 200 - 250 g | 150 - 200 L | 1.5 g/L | As per Label |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Refer to the product booklet for specific PHI by crop.
How to Apply: Best Practices
- Timing: Apply prophylactically (preventively) before disease appearance or at the very first sign of disease.
- Mixing: Fill the spray tank halfway with water, add the required quantity of Cosuit granules, and stir well. The advanced formulation disperses rapidly.
- Coverage: Ensure thorough coverage of both the upper and lower surfaces of the leaves, as this is a contact fungicide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying near water bodies (ponds, rivers).
Frequently Asked Questions
1. Is FMC Cosuit a fungicide or a bactericide?
It is both! Cosuit is a dual-action product that effectively controls both fungal diseases (like Downy Mildew) and bacterial diseases (like Bacterial Leaf Blight).
2. How is Cosuit better than Copper Oxychloride (COC)?
Cosuit uses Copper Hydroxide in a WG formulation. This provides higher "bio-availability" of copper ions, meaning you need a lower dose (grams per acre) to achieve better results compared to bulkier COC powders.
3. Can I mix Cosuit with other products?
Yes, Cosuit is generally compatible with most insecticides and fungicides. However, do not mix it with highly acidic or highly alkaline products (like Lime Sulphur). Always perform a jar test first.
4. Does it leave residue on crops?
Cosuit is designed to be effective at lower doses, which helps in managing residues better than older copper formulations, making it suitable for export-oriented crops like Grapes and Tea when used according to label PHI.
5. Is it safe for the sprayer?
The WG (Wettable Granule) formulation is virtually dust-free, which significantly reduces the risk of inhalation during mixing compared to dusty powders.
