Biochemical identity and physiological action
- Chemical nature: A saturated primary alcohol containing 30 carbon atoms (1-triacontanol), formulated in micro-emulsions (0.05% EC or 0.1% EW).
- Stimulates adenosine triphosphate (ATP) production and increases chlorophyll density within plant chloroplasts.
- Upregulates key photosynthetic enzymes (such as RuBisCO), accelerating carbon assimilation and vegetative dry matter accumulation.
- Promotes lateral root branching, enhances nutrient absorption, and reduces premature flower and fruit drop.
Crop applications and beneficial stages
- Horticultural vegetables (tomato, chilli, brinjal, cucurbits): Enhances branch development, flower retention, and uniform fruit set.
- Field crops (cotton, pulses, soybean): Reduces floral shedding, promotes pod filling, and boosts overall harvest yield.
- Fruit orchards (mango, grapes, citrus): Enhances berry and fruit sizing, skin finish, and post-harvest keeping quality.
- Tea and plantation crops: Accelerates new flush emergence and tender shoot growth between harvest rounds.
Application methods and dilution guidelines
- Apply as a fine foliar spray during early vegetative, pre-flowering, and early fruit formation windows.
- Spray during early morning or late afternoon hours when stomata are open and heat stress is minimal.
- Follow CIBRC approved label dosages, using recommended personal protective equipment and clean mixing water.

Common questions
What is Triacontanol in agriculture?
It is a natural plant growth regulator that boosts photosynthesis, vegetative growth, flowering, and crop yields.
How does Triacontanol improve crop performance?
It increases chlorophyll content, accelerates RuBisCO enzyme activity, and enhances nutrient and water uptake.
Which crops benefit from Triacontanol applications?
Vegetables, fruits, cotton, pulses, tea, and cereals all benefit when treated at key vegetative and flowering stages.
Can Triacontanol be mixed with foliar fertilizers?
Yes, it is commonly tank-mixed with water-soluble fertilizers and micronutrients, subject to product compatibility.
