phylgreen 200

Phylgreen 200 is a 100% active, cold processed extract of Ascophyllum nodosum seaweed kelp plant biostimulant.

Ascophyllum nodosum only grows in a few cold water locations in the North Atlantic Ocean. Tradecorp hand cut fresh Ascophyllum nodosum seaweed kelp from rocks at low tide and immediately extract Phylgreen at our shoreline factory using Tradecorp's unique gentle low temperature cold process. This ensures a high level of active components in Phylgreen 200 that are beneficial to crops.

Ascophyllum nodosum is internationally recognized and scientifically proven to be the richest source of plant stimulating components

  • Phylgreen 200 contains active components that are preserved by our gentle low temperature cold extraction process
  • These active components include Alginates, Mannitols, Polysaccharides and Polyphenols
  • Phylgreen 200 components influence germination and sprouting, flowering and fruit set, and reduce the impact of climate and salinity stress
  • Phylgreen 200 naturally contains hormone-like plant activators that actively promote vegetative and root growth
  • 100% water soluble so will not block sprayers or drippers
  • Australian Organic Registered Farm Input
  • Highly compatible with most commonly used agrochemicals and fertilizers, check label for details
  • Does not contain artificial hormones



Ascophyllum nodosum belongs to the family of brown seaweed the Phaeophyceae

    • Ascophyllum nodosum grows in the tidal zone where it is submerged or out of the water twice per day
    • Living in the tidal zone  Ascophyllum nodosum is adapted to withstand and thrive in an extremely stressed growth environment:

      — water stress from being submerged in seawater and then drying in the sun when the tide goes out

      — saline stress from dissolved salts naturally present in seawater

      — physical stress from the ebb and flow of tides compounded by the action of waves

      This is one of the most difficult growth environments in the world for plants

    • To protect itself from such extreme conditions Ascophyllum nodosum produces a broad range of active components including Alginates, Mannitol, Polysaccharides like Laminaran and Polyphenols
    • Ascophyllum nodosum contains a much higher content of active components compared to other seaweeds as a result of living in the tidal zone
    • Tradecorp’s unique gentle low temperature cold extraction process preserves these beneficial active components that are lost during harvest and extraction of other seaweed products

Ascophyllum nodosum only grows in the cold waters of the North Atlantic. The main growth areas are the sea shores of Ireland, Norway, Canada, Scotland and Maine.

Ireland has some of the best seaweed harvest and management regulations in the world. This ensures the sustainability and environmental health of the seaweed ecosystem, now and into the future. Tradecorp are licensed to harvest Ascophyllum nodosum by the Irish Government under a quota system that protects areas from over harvest and allows more than three years for the seaweed to regrow after harvest.

The north-west coast of Ireland has some of the purest growth conditions for Ascophyllum nodosum seaweed due to clean ocean currents sweeping in from the North Atlantic Ocean, low industrial activity on the western seaboard of Ireland and low oil tanker traffic. This ensures Phylgreen is free from contaminants.

Tradecorp’s aim is to maintain the natural composition of the Ascophyllum nodosum seaweed extract. This gives Phylgreen with the highest natural plant stimulating activity possible.

Tradecorp have developed a unique gentle extraction process that uses low temperatures and cell rupture (similar to how olive oil is produced) to extract the naturally occurring active components in Ascophyllum nodosum. This is in contrast to most other classical seaweed extraction processes which use heat and chemicals.

Phylgreen Gentle Extraction

Classical extraction uses high temperatures >120oC and aggressive alkaline extraction methods. The classical method denatures and destroys most active components. The principal effect on plants of seaweed products produced by classical extraction is through a fertilizer effect from the addition of extra N, P, K from the cooked seaweed extract. Phylgreen is different.

The gentle low temperature extraction process used to extract Phylgreen preserves the fragile active components. Phylgreen is rich in Alginates, Mannitols, Polysaccharides and Polyphenols that are destroyed by classical extraction. These active components interact with the plant on a cellular, molecular and hormonal-like level stimulating the plant to grow stronger, healthier and more vigorously, rather than simply fertilizing the plant. That’s the Phylgreen difference.
