KaitoSol® is a foliar biostimulant which is 100 % natural. It is based on ActiveChitosan, a molecule made from plant and shrimp extracts. It is soluble in water and it is applied at the beginning or through out the life cycle of the crop (depends on crop) by manual or mechanical spraying. It is manufactured by a fermentation process. It does not contain any harmful chemicals or genetically modified compounds.
ActiveChitosan is the main active ingredient in KaitoSol®. It is made from plant and shrimp extracts and  it has a highly optimised structure when compared to regular chitosan*. The optimised size and uniformity of the molecule creates a highly active compound. The molecule was developed at The University of Cambridge.


*Chitosan is a modified carbohydrate polymer derived from the chitin component of the shells of crustacean, such as crab, shrimp, and cuttlefish.


ActiveChitosan vs. Standard Chitosan


How KaitoSol® works


KaitoSol® is applied to the leaves and trunk of the plants via spray. In some cases, the product is applied to the soil either via drip or via spray.



  • It has high adherence properties, creating a nurturing layer,
  • and it acts as a natural barrier against external agents



Since the molecule remains attached to the plant for an extended period, there is good absorption and small loss of active material. ActiveChitosan, as it is absorbed, enhances the strength of the plant and provides to the plant nutrients.



What happens:

  • Increases yield
  • Reduction in growth time
  • Aids on preventing disease
  • Enhances the strength of the plant
  • Induces chitin & phytoalexin enzymes
(It is important to mention that KaitoSol® is not a replacement of standard fertilizers and should be used as an addition to standard practices. However, it has been noticed that the use of KaitoSol® might reduce usage of pesticides and fertilizers).

Always read the Technical Data Sheet (available for download from the website) and the Material Safety Data Sheet (available for download from the website) before use.


General Guidelines

Trees or similar Fruit trees, palm oil. 300 mL per 100 liters of water Monthly
Greenhouse vegetables Lettuce, tomatoes, cucumbers 400 mL to 800 mL per 100 liters of water 5 to 15 days interval depending on the crop’s life cycle
Medium cycle crops Rice, corn, wheat, etc. 0.5 – 2 L/Ha Apply 3 to 4 times in the first 2 to 3 months of the crop.

(The dosage is an indicative figure only. It depends on the crop type, stage of its life cycle and weather conditions, amongst others. For further details on application procedures, refer to the brochure or contact your distributor)
