Regalia® Maxx

Regalia® Maxx is sold as a higher concentrate outside the US and used to control powdery mildew, blight, Anthracnose and other bacterial diseases.

Regalia Maxx works from the inside out, by triggering treated plants’ natural defense mechanisms to produce disease-fighting biochemicals, while simultaneously enhancing plant health, crop yield and crop quality. Regalia Maxx is an organic fungicide that is exempt from residue tolerances (MRLs = maximum residue levels). It is approved for suppression of Powdery mildew and Gray mold (Botrytis) for indoor commercial medicinal plant growers in Canada.
