Product details
Cosuit Fungicide | Copper Hydroxide 61.41% WG
Cosuit is a copper hydroxide 61.41% WG contact fungicide with multi-site activity. It protects treated plant surfaces against specified diseases and depends on thorough, even coverage rather than systemic movement.
What it controls: Specified fungal diseases on treated plant surfaces.
When to use it: Within the labelled preventive disease programme.
What to include: Even surface coverage and a properly dispersed WG suspension.
Why Choose This Product? Key Benefits
- 🌿Multi-site copper activity: Copper acts at several fungal sites, distinguishing it from a single-site fungicide.
- 🎯Protective surface coverage: The contact treatment protects the plant surfaces reached by the spray.
- 🌱Disease-specific crop choices: The named uses include downy mildew, late blight, anthracnose, smut and blister blight, each paired with its own crop.
- 🔬Water-dispersible granules: The WG formulation is dispersed in water for spraying and measured by weight rather than as a liquid concentrate.
- 🛡️Different stewardship role: FRAC Group M01 offers a different mode-of-action category from systemic single-site fungicides, without implying that any tank mixture is approved.

How It Works: Mode of Action
Cosuit belongs to the multi-site copper group M01. Because it acts by contact, disease-management timing and surface coverage are especially important.
- Deposit on the crop: Disperse the granules according to the leaflet and cover the target plant surfaces evenly.
- Release active copper: Copper at the treated surface interacts with susceptible pathogens that encounter the deposit.
- Disrupt several fungal processes: Multi-site activity interferes with multiple cellular functions, rather than a single biochemical target.
Multi-site activity does not remove the need for the crop-specific label programme. Do not infer tank-mix approval from the mode-of-action classification.

Dosage & Application Guide
These foliar programmes use different product amounts, water volumes and harvest intervals. Paddy false smut has a longer waiting period than the other listed uses.

Approximate acre equivalents retain the original hectare figures below them. Match each product amount with its stated water volume and harvest interval.
No per-litre rate is derived. Keep the crop-specific product amount matched to its prescribed water volume, including the water range where shown.
How to Apply: Best Practices
- Timing: Use preventively when the first disease symptoms are observed or weather favours disease development, as directed by the leaflet.
- Repeat applications: Where needed, the leaflet permits a 7–10-day interval according to disease severity, with no more than 4 applications in a crop cycle. Always preserve the crop-specific harvest interval.
- Equipment and coverage: Use high-volume spraying equipment such as a knapsack sprayer with a flood-jet nozzle. Ensure thorough, uniform coverage; Cosuit is a contact treatment.
- Mixing: Mix the measured product with a small amount of water, then add the remaining specified volume with thorough agitation. Do not infer approval for additional tank-mix partners.
- Spray-water restriction: The leaflet warns that phytotoxicity may occur if the spray solution pH is below 6.5. Do not treat acidic mixtures as automatically suitable.
- Re-entry: Do not enter treated areas for 48 hours and until the spray has dried. Keep unprotected people and animals away during treatment.
Frequently Asked Questions
What does the formulation code mean?WG means water-dispersible granules. The copper hydroxide content is 61.41%; measure the formulation by weight and disperse it according to the leaflet.
Why is coverage particularly important with Cosuit?The product acts where the spray is deposited. It does not move systemically to compensate for untreated surfaces, so even distribution is central to its use.
Is Cosuit systemic or residue-free?Cosuit is a contact copper fungicide, not a systemic treatment. No residue-free claim is made here; observe the crop-specific waiting period and all label restrictions.
Does spray-water pH matter?Yes. The leaflet warns of phytotoxicity when the spray solution pH is below 6.5. This is also a reason not to assume compatibility with acidic tank-mix products.
What should be checked before application?Check the supplied label for product amount, water, timing, harvest and re-entry restrictions, protective equipment and any crop-specific precautions.
Safety & Disclaimer
Read and follow the supplied product label and accompanying leaflet. Use only for the stated crop, target and application conditions, and observe the applicable dose, waiting periods and precautions.
Avoid inhalation and contact with eyes and skin. Do not eat, drink or smoke during mixing or application. Store closed in its original container away from food, feed, heat and children.
Do not reuse empty pesticide containers. Follow label disposal instructions and keep product and washings out of ponds, streams and drains.
Wear long sleeves, long trousers, chemical-resistant gloves and covered shoes. Use the label-required mask and goggles during mixing and loading. Never blow a blocked nozzle clear with the mouth.
