Citric Acid based Fungicides

Citric Acid & Oxidizer Based Fungicides

Citric acid and oxidizer-based fungicides offer a low-residue, fast-acting solution for controlling powdery mildew, botrytis, pythium, and other fungal and bacterial pathogens in commercial greenhouse operations, controlled environment agriculture (CEA), and certified organic farms.

These formulations — including hydrogen peroxide, peroxyacetic acid, and citric acid chemistries — are FIFRA 25(b) exempt or EPA registered with short re-entry intervals (REI). They are well-suited for use in IPM rotation programs where low residue, rapid pathogen knockdown, and worker safety are priorities. Many are also effective as equipment and surface sanitizers.
