Eden Research plc, a UK-based leader in sustainable biopesticide and biocontrol technologies, has announced a significant regulatory achievement with the approval of its flagship product, Mevalone®, for the control of powdery mildew in grapes in California. This approval represents a meaningful expansion of Mevalone’s application in one of the world’s largest and most influential agricultural markets, particularly in viticulture.

Previously approved in California for the control of Botrytis cinerea—a common fungal pathogen affecting grapevines—Mevalone’s extended label now includes powdery mildew, another major disease that threatens vineyard health and productivity. The addition significantly enhances Mevalone’s value proposition for grape growers seeking effective, sustainable solutions to protect crop quality and yield without resorting to conventional synthetic fungicides.

California’s wine and table grape industries are globally recognized, with growers increasingly prioritizing environmentally responsible practices and residue-free produce. Mevalone, a biologically derived, terpene-based fungicide, is well aligned with this shift, offering reliable disease control with minimal environmental impact. Its natural mode of action makes it compatible with integrated pest management (IPM) programs and organic farming standards in many regions.

According to Eden Research, the product will be promoted by Sipcam Agro USA, the exclusive distributor of Mevalone in the United States. With this latest development, Sipcam Agro USA will now target both Botrytis and powdery mildew control, expanding Mevalone’s commercial potential across California vineyards. Updated product labels and marketing collateral are expected to be released ahead of the current growing season, ensuring that growers can take immediate advantage of this expanded use.

While Eden sees this approval as a strategic enhancement that may strengthen Mevalone’s competitive position among botryticides and general fungicides, the company does not anticipate a major near-term impact on its revenue guidance. Instead, the move is viewed as a long-term growth opportunity, aligning with Eden’s commitment to supporting growers with science-backed, sustainable crop protection solutions.

Sean Smith, CEO of Eden Research, has consistently emphasized the importance of innovation, regulatory progress, and strategic partnerships in scaling the company’s impact across global markets. This latest approval is a testament to Eden’s ongoing efforts to expand Mevalone’s reach, increase grower confidence, and contribute to a more sustainable agricultural future.

As the demand for eco-friendly, effective alternatives to chemical pesticides continues to rise, Mevalone’s dual-action label in California marks a positive step forward—not only for Eden and its distribution partners, but also for a viticulture industry seeking smarter, safer, and more sustainable ways to protect their crops.
