Grostimula™EW is a unique biological plant growth promoter that widens and lengthens the opening of stomata, thereby enabling better intake of carbon dioxide, better photosynthesis and respiration, and increased yield of crops. Grostimula™EW is used as an effective foliar spray. It is formulated as an Emulsion in water.


  • Aids in stomatal opening, thereby increasing the rate of photosynthesis.
  • Promotes the natural enzymatic and hormonal plant activities as it contains natural stimulants.
  • Reduced leaf drop, flower drop and fruit drop.
  • Aids in mineral uptake from soil.
  • Increases grain / fruit yields because of enhanced photosynthetic duration.
  • A plant growth promoter that helps in increasing yield of crops.

How does it work

Grostimula™EW prolongs stomatal opening and thereby increases respiration and photosynthesis. This increased photosynthesis leads to faster cell division, which produces greater root and shoot mass. Grostimula™EW, when sprayed during growth phases of plants, activates the secondary messengers in the plant cells, which aids in enhanced enzymatic activities in plants, thus promoting higher yield.

Active Ingredients

The major active ingredient of Grostimula™EW is Triacontanol EW 0.1 % formulated as an Emulsion in Water (EW).
Grostimula™EW is based on water as a carrier, thus no fossil fuel-based carrier solvent is used in its formulation. Therefore, not only is the active biological and non-toxic, the carrier in the formulation is also non- toxic and ecological.
