Miraculan (Triacontanol 0.05% EC) by Corteva Agriscience
Unlock the full genetic potential of your crops with the original metabolic booster.
Miraculan is a premium Plant Growth Regulator (PGR) trusted by Indian farmers for decades. Unlike standard tonics, it works at the cellular level using Triacontanol 0.05% EC, a powerful photosynthesis enhancer. Originally developed by Dow AgroSciences (now Corteva), Miraculan bridges the gap between your crop's potential and its actual yield.
Best For: Boosting yield in Cotton, Paddy (Rice), Chilli, Tomato, Potato, and Fruits by improving metabolic activity and stress resistance.
Why Choose This Product? Key Benefits
-
⏱️
Rapid Absorption Technology: The unique solvent-based EC formulation penetrates the leaf's waxy layer instantly, delivering results faster than water-based alternatives.
-
🛡️
Stress & Drought Resistance: It regulates "Aquaporins" (water channels) in plant cells, helping crops survive low moisture conditions and recover from heat stress.
-
⏳
Prevents Flower & Fruit Drop: Strengthens the connection (pedicel) between the plant and the fruit, significantly reducing shedding in Cotton and Chillies.
-
🌧️
Boosts Nutrient Uptake: Acts as a "metabolic pump," increasing the activity of enzymes that help the plant absorb fertilizers (Nitrogen) more efficiently.
-
🌿
Greener, Healthier Crops: Increases chlorophyll density and RuBisCO activity, keeping plants greener for longer ("Stay Green" effect) for maximum grain filling.

How It Works: Mode of Action
Miraculan is not a hormone; it is a metabolic elicitor. Upon application, it triggers a rapid reaction known as the "TRIM" (Triacontanol Rapid Elicitor Message) signal.
- Activation: The solvent helps the active ingredient penetrate the leaf cuticle instantly. This triggers the production of secondary messengers (adenosine) that travel from leaves to roots.
- Photosynthesis Boost: It upregulates the genes responsible for RuBisCO (the enzyme that fixes CO2), allowing the plant to create more food (sugar/starch) from sunlight.
- Nutrient Pumping: It alters cell membrane permeability, allowing the roots to absorb water and minerals (Nitrogen, Potassium) more freely from the soil.
This results in a plant that is physiologically optimized to convert sunlight and fertilizer into harvestable yield (cotton bolls, grains, or fruits).
Target Crops & Benefits
| Crop | Key Benefits & Target Issues |
|---|---|
| Cotton | Reduces square (bud) dropping, increases boll size, and improves fiber quality. |
| Paddy (Rice) | Increases productive tillers, reduces chaffy grains, and helps withstand cold stress in Rabi. |
| Chilli & Tomato | Prevents flower drop, ensures uniform fruit size, and enhances color (lycopene) development. |
Dosage & Application Guide
The Golden Rule: The optimal dose is 0.5 ml to 1.0 ml per Litre. Do not overdose, as this product is highly concentrated.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | Timing |
|---|---|---|---|---|
| Cotton | 250 - 300 ml | 200 L | 1.25 - 1.5 ml | 1st: 40-45 Days 2nd: 60-70 Days 3rd: 90 Days |
| Rice | 250 ml | 150 - 200 L | 1.25 ml | 1st: Active Tillering 2nd: Panicle Initiation |
| Vegetables | 200 - 250 ml | 150 - 200 L | 1.0 - 1.25 ml | Pre-flowering & Fruit development |
*For best results in high-volume sprayers, a standard dose of 1.0 ml per Litre is recommended.
How to Apply: Best Practices
- Timing: Apply during cooler hours (early morning or late evening). Avoid spraying when temperatures exceed 35°C to prevent leaf burn from the solvent.
- Mixing: Compatible with soluble NPK fertilizers (like 19:19:19). Add Miraculan to the water last. Avoid mixing with highly alkaline products like Bordeaux mixture.
- Coverage: Ensure full foliar coverage. The "EC" formulation helps it stick, but uniform spraying ensures the "TRIM" signal reaches the whole plant.
- Safety: Always wear PPE (gloves, mask, goggles). This product contains solvents that are flammable—keep away from open flames.
Frequently Asked Questions
1. How is Miraculan different from Vipul or other boosters?
Miraculan uses a specialized petroleum-based solvent (EC formulation) that penetrates the waxy leaf surface better than water-based (EW) generics, ensuring faster results even at lower doses.
2. Can I use Miraculan on a crop stressed by drought?
Yes, absolutely. It helps open "water channels" (aquaporins) in the cells, allowing the plant to utilize limited soil moisture more effectively.
3. Will overdosing give better yield?
No. Triacontanol works on a "Goldilocks" principle. Too much (over 3ml/L) can cause leaves to curl. Stick to the recommended 0.5 - 1.0 ml/L range.
4. Is it effective for Leaf Curl Virus in Chilli?
Miraculan cannot cure the virus, but it helps the plant recover biomass and produce new leaves/flowers rapidly after the pest vector has been controlled.
5. Can I mix it with fungicides?
Yes, it is compatible with most insecticides and fungicides. Always perform a small "jar test" before mixing in the main tank.
