Radisei™ an agricultural biostimulant with the power of bacillus subtilis

Radisei™ is an agricultural biostimulant designed to achieve maximum power, based on our own SEIBS23 Bacillus subtilis strain. Radisei™ activates different soil biological processes, it unlocks essential micro and macronutrients and produces enhanced development of the root system, encouraging a robust start for crops that ensures a high-quality final production.

Thanks to power provided by our own, exclusive Bacillus subtilis strain, Radisei™ acts both on plant root systems and on soil biological processes. It reduces the impact of stress caused by situations of adverse temperature, salinity and water stress and, as an agricultural biostimulant, it exercises an effect that improves the root system architecture and stimulates root growth.

Key points of Radisei

  • As Radisei™ incorporates a plant growth promoting bacteria (PGPR), it improves the root system architecture and stimulates growth of secondary roots and absorbent hairs.
  • It provides bioactive compounds with an optimal C/N ratio, together with organic acids, amino acids and vitamins. 
  • It encourages the unlocking of soil micro and macronutrients that are essential for optimal plant development, and also increases the plant's capacity to assimilate them.
  • Stress modulation by plants in situations of extreme temperatures, salinity and water shortage.
  • The biofilm generated on the whole of the root establishes a powerful biological and physical barrier and creates a symbiotic relationship that is unique to this Bacillus subtilis strain.
