Novellus+ Regulatory Authorisation in Chile

Eden receives its first authorisation in South America, in one of the world's largest wine-exporting markets

Eden Research plc (AIM: EDEN), a leader in sustainable biopesticide and biocontrol technologies, is pleased to announce that it has received regulatory authorisation in Chile for the fungicide Novellus+^™. The approval, granted by the Chilean Ministry of Agriculture, applies to its use in wine and table grapes to control grey mould (Botrytis cinerea) and powdery mildew (Uncinula necator). Novellus+ provides excellent protection for grapes with no residues and can be applied up to one day before harvest. Sipcam Chile SpA, the local affiliate of Sipcam-Oxon, will be the exclusive distributor.

Chile is recognised as one of South America's leading agricultural markets, driven by strong export demand and a favourable climate for year-round production. Chile is the third largest wine producer in the Southern Hemisphere, with a five-year average production of 11.3 million hectolitres (mhL) per year. Globally, Chile was the fourth-largest wine exporter in 2024, with approximately 70% of the total production exported. Furthermore, with nearly 50,000 hectares of table grapes grown, Chile is the second largest producer and exporter of grapes in the Southern Hemisphere.

Overall, the Chilean crop protection market is the fourth-largest market in LATAM, estimated to be $735 million in 2022 and projected to grow to over $834 million by 2027. Conventional chemical pesticides are rapidly being replaced by organic and biological solutions as a consequence of the pressure from consumers and retailers, and this migration to more sustainable solutions has been set as a priority by the government of Chile, which is boosting international promotion of its organic food production.

Sean Smith, CEO of Eden Research, commented:

"The approval of Novellus+^™ in Chile is a milestone for Eden in our effort to deliver sustainable solutions to growers and to the food chain globally. The Chilean market is particularly attractive as well-recognised exporters of grapes and wine with a strong commitment to delivering the highest standards in their products. Working alongside Sipcam-Oxon, we are excited to expand our business in one of the fastest-growing markets for biological crop protection. Moving forward, we intend to expand the Novellus+^™ label to include other high-value crops. Given the clear intention of the local industry and regulators to move towards more sustainable agriculture, we are confident that our first step into South America will deliver excellent results for our partner, growers, and Eden's stakeholders."

Notes to Editors:

Eden Research is the only UK-listed company focused on biopesticides for sustainable agriculture. It develops and supplies innovative biopesticide products and natural microencapsulation technologies to the global crop protection, animal health and consumer products industries.

Eden's products are formulated with terpene active ingredients, based on natural plant defence metabolites. To date, they have been primarily used on high-value fruits and vegetables, improving crop yields and marketability, with equal or better performance when compared with conventional pesticides. Eden has three products currently on the market:

Based on plant-derived active ingredients, Mevalone® is a foliar biofungicide which initially targets a key disease affecting grapes and other high-value fruit and vegetable crops.  It is a useful tool in crop defence programmes and is aligned with the requirements of integrated pest management programmes. It is approved for sale in a number of key countries whilst Eden and its partners pursue regulatory clearance in new territories thereby growing Eden's addressable market globally.

Cedroz™ is a bionematicide that targets free living nematodes which are parasitic worms that affect a wide range of high-value fruit and vegetable crops globally.  Cedroz is registered for sale on two continents and Eden's commercial collaborator, Eastman Chemical, is pursuing registration and commercialisation of this important new product in numerous countries globally.

Eden's seed treatment product, EcovelexÔ was developed to safely tackle crop destruction caused by birds - a major cause of losses in maize and other crops. Ecovelex works by creating an unpleasant taste or odour that repels birds, leaving the seeds safely intact and the birds unaffected and free to find alternative food sources. The product is based on Eden's plant-derived chemistry, registered in the EU, U.S. and elsewhere, and formulated using Eden's Sustaine® microencapsulation system.

Eden's Sustaine^® encapsulation technology is used to harness the biocidal efficacy of naturally occurring chemicals produced by plants (terpenes) and can also be used with both natural and synthetic compounds to enhance their performance and ease-of-use. Sustaine microcapsules are naturally-derived, plastic-free, biodegradable micro-spheres derived from yeast. It is one of the only viable, proven and immediately registerable solutions to the microplastics problem in formulations requiring encapsulation.

Eden was admitted to trading on AIM on 11 May 2012 and trades under the symbol EDEN. It was awarded the London Stock Exchange Green Economy Mark in January 2021, which recognises London-listed companies that derive over 50% of their total annual revenue from products and services that contribute to the global green economy. Eden derives 100% of its total annual revenues from sustainable products and services.
