Equation Pro Fungicide: The Ultimate Solution for Blight & Mildew
Get superior protection for your high-value crops with Corteva’s dual-action technology.
Equation Pro is a world-class fungicide designed to fight tough Oomycete diseases like Late Blight and Downy Mildew. It combines two powerful active ingredients to provide a "double shield" for your plants. It works by protecting the leaf surface and penetrating inside to kill hidden infections, making it the perfect choice for tomato, potato, and grape farmers.
Best For: Controlling Late Blight, Early Blight, and Downy Mildew in difficult weather conditions.
Why Choose Equation Pro? Key Benefits
- ⏱️Kick-Back Action: Stops disease even if applied 24-48 hours after infection starts (curative action).
- ?️Double Protection: Two active ingredients prevent the fungus from developing resistance.
- ⏳Rainfast in 2 Hours: Sticks to the leaf wax quickly, so it doesn't wash off during rain.
- ?️Weather Proof: Ideal for monsoon spraying when blight pressure is highest.
- ?Harvest Friendly: Short waiting period (PHI) of just 3 days for vegetables like tomatoes and cucumbers.

How It Works: Mode of Action
Equation Pro uses a "Dual-Front Attack" to stop fungus in two ways:
- Famoxadone (The Shield): This ingredient stays on the leaf surface and binds to the wax. It acts as an energy blocker, stopping the fungal spores from breathing and moving. It kills spores on contact before they can enter the plant.
- Cymoxanil (The Healer): This ingredient penetrates the leaf tissue (local systemic action). It finds fungus that has already entered the plant and destroys it by disrupting its metabolism. This provides the "kick-back" cure.
- Synergy: Together, they prevent the disease from spreading (Antisporulant) and protect new growth through translaminar movement.
Result: Complete protection from both the outside and the inside.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Tomato | Late Blight (Phytophthora) & Early Blight (Alternaria) |
| Potato | Late Blight (Protects leaves and tubers) |
| Grapes & Cucurbits | Downy Mildew |
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 (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Tomato / Gherkin | 200 ml | 200 L | 1 ml | 3 Days |
| Potato | 200 - 250 ml | 200 L | 1.25 ml | 14 Days |
| Grapes | 200 ml | Varies | 1 ml | 28 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Spray preventatively before disease appears, or immediately after rain. Repeat every 7-10 days if disease pressure is high.
- Mixing: Shake the bottle well. Mix the required amount in a small mug of water first to make a slurry, then add to the main tank. Keep the water agitated.
- Coverage: Use sufficient water. Ensure the undersides of leaves are covered, as this is where Downy Mildew hides.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not mix with alkaline products like Bordeaux mixture.
Frequently Asked Questions
1. Does Equation Pro work if it rains?
Yes. It becomes "rainfast" within 2 hours of spraying. Once dry, it sticks to the leaf wax and won't wash off easily.
2. Can it cure disease that is already visible?
Equation Pro has "kick-back" action. It can stop infections that occurred 24-48 hours ago, even if you can't see them yet. However, for visible severe damage, it acts as an anti-sporulant to stop spread.
3. Can I mix it with other products?
Do not mix with alkaline products (like Lime Sulfur or Bordeaux). Avoid mixing with Propiconazole (Tilt) during flowering to protect bees.
4. Is it safe for harvesting vegetables?
Yes, it has a short waiting period. For tomatoes and gherkins, you can harvest the crop just 3 days after spraying.
5. Does it control Early Blight too?
Yes, unlike many other Oomycete-specific fungicides, Equation Pro is also effective against Early Blight (Alternaria) in tomatoes.
