2. Key Active Components

  • Polysaccharides (alginates, laminarin, fucoidan)
  • Natural plant growth hormones (auxins, cytokinins, gibberellins)
  • Amino acids and short peptides (≥ 4% w/w)
  • Osmoprotectants (mannitol, betaines)
  • Vitamins (B-group, C, E) and phenolic compounds
  • Natural marine minerals and chelating agents

3. Benefits & Mode of Action

This balanced 12% seaweed extract offers cost-effective and reliable biostimulant performance suitable for broad-acre and horticultural use:

  • Promotes healthy root development and increases nutrient and water absorption capacity of the root zone.
  • Enhances chlorophyll formation and photosynthetic efficiency, supporting steady vegetative growth and improved plant stamina.
  • Strengthens natural plant defenses, providing moderate to good tolerance against drought, salinity, heat, and cold stress.
  • Encourages uniform flowering and fruit set, reduces flower and young fruit drop, and contributes to higher marketable yield and better crop quality.
  • Stimulates soil microbial activity and improves soil structure and cation exchange capacity over repeated applications.
  • Serves as a natural chelator, improving availability and uptake of macro- and micronutrients from soil and applied fertilizers.

4. Compatibility

Fully compatible with most soluble fertilizers, fungicides, herbicides, and insecticides. Avoid tank-mixing with products of pH > 11 or high free calcium content without prior jar testing.

5. Storage & Shelf Life

  • Store in a cool, shaded area (5–30 °C)
  • Protect from freezing and prolonged exposure to direct sunlight
  • Shelf life: 36 months from date of manufacture when stored correctly
  • Keep container tightly closed when not in use

6. Packaging

  • 500 ml, 1 L, 5 L, 20 L HDPE bottles/drums
