First Approved Plant Extract-Based Fungicide in Brazil Brings Growers New Solution for Protecting Against Disease, Resulting in Higher Quality and Yields

December 17, 2014, DAVIS, CA — 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 a product registration from Brazil’s Ministry of Agriculture (MAPA). Brazil now joins Peru, El Salvador, Guatemala, Honduras, Panama, Columbia, the Dominican Republic and Mexico as Latin American countries having approved the use of REGALIA MAXX to control a wide variety of bacterial and fungal diseases across an array of agricultural crops.

REGALIA MAXX is the first plant extract-based fungicide approved in Brazil and 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. The newly approved uses for REGALIA MAXX in Brazil, include tomatoes, potatoes, and dried beans.  MBI is working with its partner FMC to expand the label to include a broader array of crops and diseases, such as citrus and row crops.  

“REGALIA MAXX brings Brazilian growers an environmentally responsible and effective solution for protecting against a variety of fungal and bacterial diseases, resulting in higher quality and improved yields,” said MBI, CEO Pam Marrone.  “This registration is critical to our global expansion plan for MBI products and we believe it will fill a real need for growers in Brazil. REGALIA MAXX can be used as a standalone product or in combination with other fungicides to strengthen integrated pest management programs, improve plant health and boost yields.”

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 four-hour 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 control diseases such as powdery mildews on cucurbits (melons, cucumber, zucchini), cane berries, tomatoes (including tomatillo), eggplant, peppers, grapes and ornamentals; Alternaria on tomatoes and potatoes; anthracnose on avocado, mango, papaya and citrus.
