Plant growth regulator




Triacontanol/ 1-triacontanol is a linear saturated fatty alcohol as plant growth stimulator found in the plant cuticle waxes, which is healthy and safe for human and animal use. Its efficiency is proved for high yield in the case of number of field crops like rice, wheat, tomatoes, maize, lettuce, cucumber, potatoes, cauliflower, etc. The best results have been extremely impressive and have given over 100% increases in yields. The latest researches suggest that triacontanol directly activates the genes that control photosynthesis. These genes in turn activate the enzymes controlling the chemistry of photosynthesis.

Triacontanol (TRIA) is a natural plant growth regulator found in epicuticular waxes. It is used to enhance the crop production in millions of hectares, particularly in Asia. Quite a number of researchers have reported the TRIA-mediated improvement in growth, yield, photosynthesis, protein synthesis, uptake of water and nutrients, nitrogen-fixation, enzymes activities and contents of free amino acids, reducing sugars, soluble protein, and active constituents of essential oil in various crops. Expectedly, TRIA enhances the physiological efficiency of the cells and, thus, exploits the genetic potential of plant to a large extent. In fact, TRIA increased free amino acids, reducing sugars, and soluble protein of rice (Oryza sativa L.) and maize (Zea mays L.) within 5 min.

Seed soaking: use 0.05-1mg/L soaking seeds of wheat,sorghum,rice etc 12-24h, can promote crop germination rate.
Foliage spray: Foliage spray with dosage 0.1-1mg/L of Triacontanol solution, can improve photosynthesis and resistance, increase yield.
Water flush: use 200-300g/ha Triacontanol with fertilizer, can improve fertilizer effect, improve fruit bearing and quality.



To promote seed germination, increase the germination rate and germination potential .

To promote plant cell division and elongation .

To promote the growth of roots, stems, leaves .

To promote germination differentiation , the increase in flower number .

Seed setting rate and grain weight .

Promote crop precocity , to improve the quality .

The promotion of plant tissue water absorption .

To promote the absorption of mineral elements .

Increase the chlorophyll content, increased photosynthesis intensity .

To increase energy storage, dry matter accumulation .

Improve the activity of some enzymes , to enhance the respiratory intensity .

To improve the cell permeability, and improve the resistance of crops.

On application, the active ingredients are quickly absorbed by the plants resulting in improved photosynthesis, increased production of plant hormones and enzymes resulting in improved dry weight accumulation, nutrient content & also retains original taste, aroma and flavour of the agro produce resulting in higher & better quality yields with cost / benefit ratios varying between 1:5 to 1:10.
  • More branching, tillering.
  • Enhances more bud density of Tea.
  • Increases new sprouts to grow.
  • Enlarge leaf area.
  • Breaks bud dormancy.
  • Increases bud vigor- No residual effect.
When to use
Tea: First spray at bud bursting stage subsequent sprays after every 21 days during the low cropping season & after every 10 to 15 days during high cropping months
Coffee: 15 days after blossom & subsequent 2 sprays at 3 weeks interval.
Cardamom: First spray at the time of blossom & second spray after two weeks of first spray.
Vegetables: First spray 3 weeks after transplant & subsequent 2 sprays at 2 weeks interval.
Fruits: First spray just before flowering & 2 sprays at 2-3 weeks interval.
For Tea & Coffee& Cardamom: Mix 1 ml. 0.1% in 2 lit of water stirr well and apply foliar spray to the point of runoff on leaves.
For Other Crops: Mix 1 ml. In 1 lit. of water stirr well and apply foliar spray to the point of runoff on leaves flowers, fruits.
