Chestnut Tannin in powder with repellent action for Biological Agriculture on all crops. Check price, doses, label and safety data sheet.


Tannisol is entirely made of Chestnut Tannin, a natural substance able to stimulate and activate plant defense mechanisms.

Chestnut Tannin is a polyphenolic molecule with complexing properties that stimulates the growth and the development of the root system of plants and also beneficial soil microflora, limiting the proliferation of phytopathogenic agents. Thanks to its acid pH, it creates an inhospitable environment to Nematodes.

Tannisol is also an effective repellent against predators and parasites, because it decreases the digestibility of food or make it repellent, acting on the flavor (astringency) and on the hardness of the tissues.

Finally, it is a powerful antibiotic, capable to defend plants from several fungal pathogens, inhibiting the hydrolytic enzymes (cellulases, pectinases, xylanases) necessary to penetrate plant tissues.

Main Funtions:

  • It has an acidifying action on soil pH;
  • It increases fruit production and quality;
  • It improves radical development and the assimilation of trace elements;
  • It reduces the damage due to parasites of the root system.
