Serifel’s active ingredient is Bacillus amyloliquefaciens strain MBI600. It is a beneficial spore-forming, rod-shaped bacterium, that colonizes the developing leaf surface of plants.
Serifel
works best as a preventative treatment before disease pathogens have
established on the plant. Application before the major disease pressure
gives Serifel time to germinate, colonize the plant surface and produce
its disease fighting metabolites.
Serifel forms a “shield of protection” against a broad spectrum of plant pathogens thanks to three modes of action.
Production
of anti-fungal metabolites: Serifel produces specific metabolites that
prevent different species of pathogens from germinating. The metabolites
cause the pathogen spores and growing hyphae to collapse, by disrupting
their cell membrane.
Competition for space: Moreover, by being
the first to occupy the limited space on the plant, Serifel physically
excludes plant pathogens from colonizing on the plant foliage.
Competition
for resources: Serifel also depletes the supply of nutrients on the
plant surface so that pathogen spores are starved to death.
Serifel Fungicide: Managing plant diseases with biological fungicides
Serifel fungicide is an innovative fungicide with three modes of action
that forms a shield of protection on plants' surfaces to protect against
disease.
