Active substances approved for maximum residue level exemption

Eden Research Plc (AIM: EDEN), the AIM-listed natural micro-encapsulation company, announces that it has received notice that the three active ingredients, which form part of multiple plant protection products developed by Eden, have been granted approval for inclusion in Annex IV to Regulation (EC) Number 396/2005, subject to the provision of confirmatory data.

Geraniol and thymol are now exempt from the maximum residue levels ("MRLs") set for many pesticides.  This translates into a clear benefit for growers when considering treatment programmes, as Eden's products can now be used without regard to concern for residues, thus allowing growers to protect their crops right up to the point of harvest.  Eugenol has previously been granted provisional approval for inclusion in Annex IV.

Eden's Chief Executive, Sean Smith, stated: "Eden and its licensees have long been aware of the potential for our naturally-derived pesticide products to deliver additional benefits to growers through their use late in the season, thereby protecting crops at a critical time and allowing maximum produce quality. Now the European Commission has helped growers to fully realise these additional benefits by granting products containing our core actives an exemption from maximum residue levels. Grape growers, for example, will no longer need to balance their desire to select an optimal harvest time to increase produce quality and sugar levels with the requirement to adhere to maximum residue levels for their late-season fungicidal treatment.  This translates into a benefit for growers and our commercialisation partners, and it strengthens the overall value of Eden's product offerings."

Eden's first product, 3AEY, was recently granted authorisation by the zonal Rapporteur Member State, Malta for the prevention and cure of botrytis in table and wine grapes.  Following this authorisation, the concerned Member States in the Southern regulatory zone have 120 days to issue their national authorisations, thereby allowing sales in key grape growing countries, including three of the top five global grape producers.  Eden's commercialisation partners such as Sipcam, Redestos and Sumi Agro France are now preparing for product launches following authorisation.

Notes:

Eden is an early stage revenue company with intellectual property and expertise in encapsulation, terpenes and environmentally friendly technologies to provide naturally occurring solutions to the global agrochemicals industry, the animal health industry, and consumer products.

Eden's encapsulation technology harnesses the biocidal efficacy of naturally occurring chemicals produced by plants (terpenes) and can also be used with hydrophobic compounds both natural and synthetic. The technology uses yeast cells to deliver a slow release of natural compounds for agricultural and non-agricultural uses. Terpenes are already widely used in the food flavouring, cosmetic and pharmaceutical industries.

Historically, terpenes have had limited commercial use in the agrochemical sector due to their volatility, phytotoxicity and poor solubility. Eden's platform encapsulation technology provides a unique, environmentally friendly solution to these problems and enables terpenes to be used as effective, low-risk agrochemicals.

With leading consultants in their respective fields, the Company is developing these technologies through innovative research and a series of commercial production, marketing and distribution partnerships.

The Company has a number of patents and has a pipeline of products at differing stages of development targeting specific areas of the global agrochemicals industry. To date, the Company has invested in the region of £12m in developing and protecting its intellectual property. Revenues earned by the Company have been modest whilst the Company has concentrated on securing patent protection for its intellectual property, identifying suitable industrial partners and entering into licence agreements.

Eden was admitted to trading on AIM on 11 May 2012 and trades under the symbol EDEN.
