Active Ingredient and Aliphatic Alcohol Chemistry
Miraculan contains Triacontanol 0.05% formulated as an Emulsifiable Concentrate (EC). Triacontanol (1-triacontanol) is a long-chain saturated primary aliphatic alcohol (C30H61OH) naturally present in plant epicuticular waxes.
Unlike synthetic growth retardants, Triacontanol acts as a natural bio-stimulant at parts-per-million (ppm) levels, triggering rapid internal enzyme cascades, accelerating adenosine triphosphate (ATP) generation, and boosting carbon dioxide assimilation.
- Active ingredient: Triacontanol 0.05 percent w/w EC
- Chemical classification: Long-chain aliphatic fatty alcohol plant growth regulator
- Biological origin: Synthesized and extracted from natural plant epicuticular waxes
- Regulatory standard: Registered under the Central Insecticides Board (CIBRC) and FCO bio-stimulant schedules
Physiological Modes of Action in Crops
When absorbed by plant stomata, Triacontanol stimulates the activity of ribulose-1,5-bisphosphate carboxylase-oxygenase (RuBisCO), the primary enzyme responsible for photosynthetic carbon fixation.
It accelerates cell division and elongation, promotes lateral root proliferation, enhances chlorophyll index, and stimulates endogenous hormonal synthesis, leading to reduced flower and fruit drop.
- Photosynthetic rate: Increases RuBisCO activity and net CO2 fixation, boosting photosynthetic efficiency
- Tillering & branching: Stimulates productive tillering in cereals and lateral branching in vegetables
- Floral retention: Reduces flower shedding and improves pollen tube elongation and fruit set percentage
- Stress mitigation: Strengthens plant cell membranes against heat waves and moisture stress
CIBRC Approved Target Crops and Spray Scheduling
The Central Insecticides Board registers Triacontanol 0.05% EC across agronomic field crops, commercial cash crops, and high-value vegetables.
Applications are scheduled across critical physiological transition stages: active vegetative growth, flower bud initiation, and early fruit enlargement.
- Paddy & Wheat: Apply at maximum tillering and panicle initiation to boost effective panicle count
- Cotton & Chilli: Spray at active square initiation and early flowering to reduce bud drop
- Vegetables (Tomato, Brinjal, Potato): Apply at pre-flowering and early tuber/fruit sizing stages
- Application timing: Spray during early morning or late evening hours for optimal stomatal absorption

Common questions
What is the active ingredient in Miraculan?
Miraculan contains Triacontanol 0.05% EC, a naturally derived plant growth regulator and metabolic stimulant.
How does Triacontanol increase crop yields?
It stimulates RuBisCO enzyme activity, accelerating photosynthesis, increasing cell division, promoting root growth, and reducing premature flower drop.
Can Miraculan be mixed with chemical fertilizers and pesticides?
Yes, Miraculan is generally compatible with most standard neutral insecticides, fungicides, and foliar fertilizers; perform a small jar compatibility test prior to bulk mixing.
