Technology

  • Leek by-products (mostly green parts of the plant) to propose new biocontrol solution relying on an under-valued resource (20% of the leak is thrown away).
    • Leek by-products (dried or extract) display a wide antifungal activity spectrum against phytopathogens such as A. alternata, P. digitatum, P. expansum, Botrytis cinerea, Fusarium oxysporum, C. cladosporoides, Rhizopus stolonifer.
    • The mode of action involves direct contact with spores, cell wall destabilization and oxidative stress. Leek by-products embed bioactive potential to prevent seed damplingoff and fruit spoilage.
    • Synergies with antifungal agents (for instance ones used in organic farming), it could be used to reduce their concentration and enhance their efficacy.
    • Easy to produce, stable in time, and resistant to temperature.

Market

  • Global market for fungicides : 17 Mds $ (CGAR +4% to 2029).
