Features Crop Protection Inputs
Biofungicide approved for use on cannabis

June 12, 2019  By Greenhouse Canada

Biofungicide Regalia Maxx has received label approval from Canada’s Pest Management Regulatory Agency, for the suppression of powdery mildew and gray mold in indoor cannabis crops.

Developed by Marrone Bio Innovations Inc. (MBI), the biofungicide will be distributed by Plant Products in Eastern and Central Canada. A distributor will be appointed for Western Canada.

“Plant Products is excited to offer Regalia Maxx biofungicide, especially to our cannabis growers. The demand for safe and easy-to-use biologicals keeps increasing and we look forward to be[ing] the go-to source for Eastern Canada,” said Chris Stickles, president of Plant Products.


Based on an extract of giant knotweed (Reynoutria sachalinensis), MBI says Regalia Maxx works by triggering the crop’s natural defense mechanisms to produce disease-fighting biochemicals, while simultaneously enhancing plant health, crop yield and crop quality. Regalia Maxx is exempt from residue tolerances (MRLs = maximum residue levels).

Chemical pesticides dominate today’s $60 billion global pesticides market, but the fastest-growing category of crop inputs is biologicals, says BMI. These effective and environmentally friendly products are growing at 10 to 20 per cent per year, compared to just two to three per cent for chemicals. When integrated into crop production and pest management programs, biologicals — including, Regalia Maxx — can offer higher-quality crops and better yields than conventional programs, says MBI.

“We are incredibly excited to have gained approval for Regalia Maxx’s extended label, opening up the Canadian cannabis market to MBI,” said Pam Marrone, founder and CEO of Marrone Bio Innovations. “We believe our strategic partnerships with leading distributors in Canada will drive
our success in penetrating this nascent market. We look forward to further growing our presence in Canada through biologicals education and other localized efforts.”
