Revitalize Bio Fungicide Concentrate

Bonide Revitalize Bio Fungicide Concentrate is a biological fungicide from Bonide containing Bacillus amyloliquefaciens QST 713 — the same or related beneficial bacterial strain used in professional fungicide products (Serenade). This OMRI-listed organic fungicide controls powdery mildew, Botrytis (grey mold), and other fungal diseases on cannabis through competitive colonization and antifungal compound production.

Bacillus amyloliquefaciens QST 713 colonizes the plant's surfaces and produces iturin and surfactin compounds that destroy fungal cell membranes. The biological mode of action means no risk of resistance development compared to synthetic fungicides.

Apply as a preventive spray throughout the grow cycle, particularly during humid conditions. Stop 7–14 days before harvest. OMRI listed. Made by Bonide, US.
