Plant Extract-Based Fungicide Brings Canadian Growers Expanded Solution for Protecting Against Disease, Resulting in Higher Quality Crops and Enhanced Yields

DAVIS, Calif., Jan. 22, 2015 — Marrone Bio Innovations, Inc. (MBI), (Nasdaq:MBII), a leading provider of bio-based pest management and plant health products for the agriculture, turf and ornamental and water treatment markets, today announced that its REGALIA® MAXX biofungicide has received approval for new uses in Canada. REGALIA MAXX is a plant extract-based advanced biofungicide that activates plants’ natural defenses to boost plant vigor, combat fungal and bacterial diseases, and enhance yield potential.

The recently approved new uses for REGALIA MAXX in Canada include outdoor and greenhouse grown ornamental plants, annual and perennial flower plants, greenhouse grown peppers, and outdoor grown highbush blueberries, apples and turf. Health Canada’s Pest Management Regulatory Agency initially approved REGALIA MAXX biofungicide in April 2012 for outdoor and greenhouse use on a variety of fruits and vegetables, as well as on wheat and ornamentals. Brock Puddicombe, Product Manager at Engage Agro “believes that these new uses will continue to help growers remain competitive as they compete in world markets.” REGALIA MAXX, will continue to be distributed exclusively in Canada by Engage Agro, a leading Canadian distributor specializing in high-value fruit and vegetable crops.

“We are pleased that REGALIA MAXX has been approved for new uses in Canada, bringing growers an expanded environmentally responsible and effective solution for managing pests in conventional and organic crops,” said MBI CEO Pam Marrone. “MBI is well-positioned to expand the footprint of REGALIA MAXX in Canada as growers look to strengthen their integrated pest management programs, improve plant health, boost yields and increase profitability.”

“The expanded use label for REGALIA MAXX will provide Ontario greenhouse vegetable producers with a valuable tool for managing powdery mildew on tomatoes and peppers and for downy mildew on cucumber, while apple, blueberry and turf growers gain an additional product to integrate into their disease control programs,” said Jim Chaput, Provincial Minor Use Coordinator for the Ontario Ministry of Agriculture, Food and Rural Affairs.

REGALIA MAXX is the first biopesticide with Induced Systemic Resistance (ISR), a complex mode of action which creates a defense response in the treated plants and stimulates additional biochemical pathways that strengthen the plant structure and act against the pathogen.

REGALIA MAXX is an advanced biofungicide that can minimize chemical residues by being used alone in a disease-control program, particularly for exported crops at the end of the season right before harvest or in rotation with synthetic fungicides or in a tank mix. The product induces a plant’s natural defenses to protect against a variety of fungal and bacterial diseases and features multiple modes of action, which helps to prevent or delay the development of disease resistance. It also provides a minimal for the REI cite re-entry interval that increases operational flexibility and a zero-day post-harvest interval so crop quality can be protected right up to harvest. REGALIA MAXX is proven to suppress diseases such as powdery mildews on cucurbits (melons, cucumber, zucchini), cane berries, tomatoes (including tomatillo), eggplant, peppers, grapes and ornamentals; as well as Alternaria on tomatoes and potatoes.
