Marrone Bio Innovations, Inc. (MBI), a leading global provider of bio-based pest management and plant health products, announced it has received a United States patent covering applications of products containing anthraquinone derivatives, such as the company's flagship product Regalia Biofungicide. The issued claims cover methods for increasing plant growth, root initiation and extension when plant roots are treated with an anthraquinone derivative. The new patent protects uses of Regalia and any future MBI products containing these active ingredients.

Data has shown Regalia applied to bare-root plants increases transplant health, and root mass and weight. Fruit weight, new root counts and plant viability have also been increased by pre-plant dip, soil drench and drip irrigation applications of Regalia. "Growers have seen firsthand for a number of years how Regalia and its anthraquinone-based active ingredient improves plant health, vigor and yield. Now, with this patent MBI is able to pursue new products and improvements using these natural product compounds to benefit growers even more," said Pam Marrone, CEO of Marrone Bio Innovations.

She adds, "This patent is a result of MBI's unparalleled capability to in-license technology, utilize our proprietary screening platform to identify new potential uses and, ultimately, create and protect unique intellectual property through new patents."
