Marrone Bio Innovations Inc. announced that two of its biofungicide products—Stargus® and Regalia®—have been approved by the United States Environmental Protection Agency (EPA) for indoor and outdoor use on hemp plants. Stargus and Regalia improve hemp plant quality and yield, as well as treat and protect hemp plants from a range of diseases, including powdery mildew, Botrytis bud rot, Sclerotinia white mold, Fusarium rots and wilts and other fungal and bacterial diseases. This is the first time that the EPA has approved crop protection products on hemp since the crop became legal to grow under the 2018 Farm Bill.
