General information


Natural product derived from chitin, is organic, bio-degradable, non-toxic, and non-polluting, this product finds its use in agriculture as a bio-stimulated crop protector.  


Its active ingredient, N-acetyl-glucosamine, (chitosan) is a polymer derived from chitin, the raw material for the production of Biorend®.  

Chitin, is the second most abundant polymer in nature, and is found in the cell walls of some pathogenic fungi, exoskeleton of insects, and bovine cartilage. Our chitosan is extracted from the shells of marine crustaceans, such as spider crab and king crab, both abundant in Chile’s Magallanes Antartica Region.


 Biorend® is being absorbed systematically by the plant either through seeds or roots. This leads to a stronger growth in the crop.


 Dueto the chitosan composition (a chitin derivative), the crop being treated thinks that it is being attacked by a pathogen and a response to this attack is induced in the plant.


 Biorend®  acts as a plant immunostimulant through the latest generation mechanism known as SAR (SYSTEMIC ACQUIRED RESISTANCE). This response manifests itself in a number of biochemical, cytogenetic, and structural changes which are being translated into a significant rise in yields and biomass. This means an effective safeguard for sowing and planting processes.  





 Some of the importan effects are:


  •    It increase harvest and yield (Fernández Rodríguez E.J. et al 2002).


  •    It enhances root and aerial system development(Ait Barka E. et al, 2003) allowing the plant to reach a greater soil volume and to absorb more water and nutrients.


  •    It significantly strengthens the resistance and degree of lignification of the plants (Walker-Simmons,M 1984) making them less susceptible to drought or cold damage, attacks by insects or fungi, especially in those cases where the root systems are affected.


  •   Stimulation of the biochemical compounds synthesis as answer in the defense mechanism of the plant against attacks of pathogens (Hadwinger et al, 1981, 1984; Hirano, S. and Nagao, N. 1989).


  •   Activation of resisintance genes and synthesis of protein inhibitors (Walkers-Simons et al, 1983).


  •   It reduces post-transplantation dehydration species for seedbed transplants, significantly improving their development and raising yields. (Bitelli, M et al. 2001).


  •    Reduce the transpiration of plants and increases the physiological efficiency in the use of water. (Lee, Y, 1999), (Bitelli, M et al, 2001)


  •    It has a fungi-static effect (Allan, C.R. and Hadwiger, L.A. 1979) on some pathogenic fungi that cause diseases of significant economic impact and which are hard to control chemically, such as Fusarium spp, Phytophthora spp, Botrytis spp, and others.


  •    It has some positive advantages for long-term storage of foods coating fruit and vegetables. (Galed, G et al. 2004).


  •    It stimulate microflora antagonist to phitopathogenic nematodes (Kloeper, J.W et al.) an it has a certain nematode-static effect for better water absorption through generating an increased number of roots and rootlets. (Magunacelaya, J.C. M. Peña. A 2005)
