Chitosan chlorhydrate controls grey mold in berries in Spain
  • (Straw)berries (Fragaria spp.)/ ESP / Chitosan chlorhydrate / Botrytis cinerea
  • Growing customer concern regarding human and environmental health problems related to chemical residues in conventional strawberry moved growers towards sustainable disease control
  • Chitosan (polysaccharide extracted from crustaceans and molluscs) directly inhibits sprouting of the germ tube and mycelial growth of several fungal plant pathogens




  • Technical result: significant reduction of disease incidence and improved quality and shelf life of pre-harvest treated strawberry
  • Economic result: residue free (straw)berries enter market at higher price
  • Sustainability (ecological, social and economical) Gains:


    • Reduction in reliance on chemical pesticides
    • Conserves biodiversity enabling resilient vine cropping systems
    • Enables regenerative land use practices


    • Promotes quality nutritious strawberry production
    • Enables worker and consumer health and wellbeing
    • Demonstrates good governance (preventative approach)


    • Circular approach reduces loss and waste
    • Supports farmers’ livelihood and value distribution
    • Improvement of financial viability
