Using Bacillus amyloliquefaciens (strain FZB24) against fungal diseases

To combat downy mildew, powdery mildew and gray mold, farmers can use a product based on Bacillus amyloliquefaciens (strain FZB24). Environmentally friendly (no impact on beneficial organisms and pollinators), this biocontrol product based on a bacterium naturally present in the soil helps partially control fungal diseases.

How does it work?

Products based on Bacillus amyloliquefaciens (strain FZB24) use 3 complementary modes of action to manage diseases caused by fungi, in preventive action^[1]:

Synthesis of biocidal substances, from the pre-activation of the product and within hours after application.
Competition on the surface of plant organs physically preventing the establishment of diseases.
Induction of the plant's natural defenses following detection of Bacillus by the vine.

To use this type of product, it is recommended to^[1]:

Pre-activate for 15 to 20 minutes in water at room temperature to reactivate the bacterium.
Use the product at temperatures above 15°C (to optimize rapid multiplication of bacteria).
Apply the product outside periods of strong light.
Repeat application in case of rainfall exceeding 20 mm.
