The Natural Elicitor


What is It?

  • CFIA-registered supplement: Reg. # 2017113A, Fertilizers Act.
  • Chitosan is a compound naturally found in crustacean shells and fungal cell walls, and can be very beneficial to plant production and growth.
  • Chitosan enhances plant survival and yield in times of heat or cold stress and drought.
  • When foliar-applied to crops it allows the plants to grow with less water.
  • Exogenous application of Chitosan has also been shown to accelerate growth and germination as well as improve the quality of flowers and fruit.
  • Applied to produce, Chitosan helps prolong their shelf life and prevents early decays.
  • Application of Chitosan can trigger plant defense responses and lead to a significant reduction in disease pressure.
  • Timing of application is also crucial for insuring a beneficial effect.

When & Why Use It?

  • The product is recommended on all crops including field, horticultural and vegetable crops as well as fruit trees, turf and ornamentals.
  • Chitosan improves seed germination and seedling establishment.
  • Apply Chitosan to improve the overall health and resilience of the crop to stressful conditions (cold, heat, drought, …).
  • Chitosan helps plants manage water use efficiency.
  • As a biostimulant, Chitosan triggers plant’s natural immunity against pathogens and can be used to complement fungicides effect.
  • Applied post-harvest, Chitosan can prolong produce shelf life.

What to Expect?

  • An improved growth and development especially under cold, hot & drought stress conditions.
  • Healthier crops often yield higher.
  • Better seed and fruit quality.

Application Guidelines

  • Follow the recommended rates and timin listed on the label for each crop and do not exceed the recommendation.
  • To prepare solution, add one half the total amount of water, add recommended volume of Chitosan and continue adding water until desired application volume is reached.
  • For foliar applications, apply with minimum volume of 10 US gal/ac.
