As the leading manufacturer and exporter of seaweed extracts in China, Shandong Jiejing Group Corporation uses technology of cell wall cold breakage and countercurrent extraction to produce green seaweed extract liquid from fresh sargassum, it is called phlorotannins, which is a unique class of polyphenolic compounds contained in brown seaweed . The production line adopts the world’s advanced automated whole-line manufacturing equipment. As soon as the product is launched, it becomes popular product. It got highly appraised of contractors, fertilizer formulators and biostimulant company.
Phlorotannins is also called Brown algae polyphenols or seaweed polyphenols, which is natural phenolic compounds extracted from seaweeds and are derivatives of phloroglucinol. It contains trace elements and polysaccharides, salicylic acid, salicylic acid, sour, jasmonic acid, etc. It has functions such as anti-oxidation, anti-bacterial, and stress resistance. It can effectively open up the transportation channel of plant nutrients in the body, improve plant resistance such as cold resistance and waterlogging resistance of crops, and improve the overall nutrient transport capacity of plants. Brown algae polyphenols have obvious inhibitory effects on a variety of bacteria, fungi, yeasts, and have strong inhibitory effects on common pathogenic bacteria such as cholera, Staphylococcus aureus, Escherichia coli, etc., moreover it has no effect at the corresponding inhibitory concentration. The polyphenol compounds in seaweeds are the main means and material basis for the prevention of pathogen invasion in the initial stage of seaweed diseases.
What’s benefits of phlorotannins for plants?
- Natural active substances stimulants: it is rich in polyphenols and polysaccharides, trace elements such as iron, manganese, copper, molybdenum, boron, magnesium and natural substances such as salicylic acid and jasmonic acid are contained too, which can effectively stimulate the production of non-specific active factors in plants and regulate the balance of endogenous hormones
- Phlorotannins have obvious inhibitory effects on a variety of bacteria, fungus, yeasts, and on common pathogenic bacteria like cholera, Staphylococcus aureus, E. coli.
- Improve the activity of antioxidant enzymes in crops and reduce the damage of superoxide free radicals to crops under adversity. Increase the thickness of crop fence tissue and sponge tissue, improve crop resistance to cold, and reduce the photoinhibition damage to leaves caused by low temperature.
What’s application of phlorotannins？
We made many experiments of phlorotannins application on fruits and crops on our demonstration field, among of which is brown algae polyphenols in tea plant. The result shows its yield increased under the press of frost condition. The budding was increased by 26% compared with the control, and the budder density increased by 38% compared with the control.
And the results of a large number of compounding experiments of phlorotannins with other agrochemicals approves that phlorotannins can be compounded with specific amino acids, humic acid, macro, medium and trace elements and other agrochemicals to produce preparation products. And phlorotannins can be used to produce irrigation or foliar fertilizer with your own formulation.
