What is RaiSan?
RaiSan is a natural biostimulant formulated with chitosan, a polymer extracted from shells of crustacean. It activates the plant’s natural Systemic Acquired Resistance (SAR) — the built-in immune response that strengthens growth and resilience.
By triggering the plant’s own defense mechanisms, RaiSan helps prevent common diseases before they start, supporting healthier, stronger crops naturally. ally.
How RaiSan can help strengthen plant defenses
Plants’ natural defenses can be activated by applying external elicitors on the leaf surface or in the soil. These botanical extracts are made up of carbohydrates, proteins, and small molecules. They act as defense inducers. External elicitors can also trigger the production, increase and storage of antibodies with antimicrobial activity. This prepares the plant to fight off pathogenic fungi and bacteria prior to the attack.
These external elicitors act naturally and do not drain energy from the plant. They have no toxicity toward humans or animals, and are not harmful to the environment.
