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.
