Corteva Miraculan PGR
Overview
-
It is a plant growth regulator (PGR) developed by Corteva Agriscience. Its active ingredient, triacontanol 0.05% EC, is a long-chain aliphatic alcohol that influences various physiological processes in plants. By enhancing photosynthesis, nutrient uptake, and enzyme activity, Miraculan stimulates robust plant growth, leading to increased yields and improved crop quality.
Key Benefits
- Enhanced Crop Yield: It has been shown to significantly increase the yields of various crops, including cotton, rice, tomato, potato, chilli, and groundnut. It promotes earlier and stronger tillering, better root development, and uniform maturity, all contributing to higher productivity.
- Improved Plant Vigor: By promoting cell division and elongation, Miraculan enhances overall plant vigor. Plants exhibit increased height, more robust stems, and healthier foliage, which are indicators of improved health and resilience.
- Increased Flowering and Fruit Set: Miraculan stimulates flowering and enhances fruit set, leading to a higher number of fruits per plant. This is particularly beneficial for fruit-bearing crops, where yield is directly related to the number of fruits produced.
- Stress Resistance: The application of Miraculan helps plants better withstand abiotic stresses such as drought, heat, and cold. It reduces the adverse effects of these stress conditions on plant growth, ensuring consistent development even under challenging environmental conditions.
- Improved Crop Quality: Miraculan enhances the quality of fruits and vegetables by improving attributes like size, weight, color, taste, and shape. This leads to produce that is more appealing to consumers and has better marketability.

Mode of Action
Triacontanol, the active component in Miraculan, influences several physiological processes in plants:
- Photosynthesis Enhancement: Increases chlorophyll content, leading to higher photosynthetic activity.
- Enzyme Activation: Enhances the activity of naturally occurring enzymes and plant hormones.
- Nutrient Uptake: Improves mineral absorption and water permeability, facilitating better nutrient transport within the plant.
- Protein Synthesis: Stimulates the synthesis of proteins, contributing to overall plant growth and development.

Application Guidelines
Dosage
- Foliar Spray: Dilute 2–5 ml of Miraculan® per liter of water.
- Soil Drench: Apply the diluted solution directly to the soil around the base of the plants.
- Seed Treatment: Soak seeds in the diluted solution for the recommended time before planting to promote early growth and vigor.
-
Timing : Apply at critical growth stages such as pre-flowering, flowering, and fruit set for optimal results. Repeat applications may be necessary, depending on crop requirements and growing conditions.
