When we are able, we will publish news on the exciting work we are doing, at our research facility at Southampton University Science Park , in the south of England.
Recent stability evaluation using the Envelop® technology platform, highlights an emerging regulatory consideration for lambda-cyhalothrin capsule suspension products, in light of the EU restriction on intentionally added microplastics to a formulation, as marketed. Comparative stability, volatility and UV-exposure studies show that the Envelop® delivery technology delivers superior performance to a market-leading lambda cyhalothrin CS product, achieving enhanced volatility control, improved physical stability, and more effective protection against photodegradation, without relying on pre-formed, non-biodegradable polymer capsules.
Envelop® is based on an emulsifiable concentrate, containing a biodegradable polymer and a tailored solvent system, that forms microcapsules in situ on dilution with water, through controlled polymer precipitation at the emulsion droplet interface, providing sustained volatility control and UV stabilisation of the active ingredient during storage and after application. By avoiding the incorporation of microplastic additives in the formulation, as marketed, the Envelop® based platform technology, more than provides the benefits of lambda cyhalothrin CS products, while remaining aligned with evolving EU and Global regulatory restrictions and sustainability expectations, in regard to microplastics.
An extensive global field trial program has been initiated, to demonstrate the benefits to both growers and the environment, that Envelop® will bring, as the commercial introduction of the platform is accelerated in appropriate markets.
Envelop® is protected by pending and granted patents, and technical details are not disclosed
Agform is pleased to announce that it has received a positive International Preliminary Report on Patentability (IPRP) from the World Intellectual Property Organization (WIPO) in respect of its Envelop® delivery technology, filed under the international Patent Cooperation Treaty (PCT).
The IPRP is an official international-level assessment which concluded that the core claims of the Envelop® technology satisfy the principal patentability criteria of novelty, inventive step, and industrial applicability.
This independent assessment represents an important milestone in the global patenting process and provides strong validation of the technical differentiation underpinning Envelop®. National phase prosecution is ongoing in selected jurisdictions in accordance with standard patent procedures.
Agform continues to develop Envelop® as a platform technology enabling advanced formulation and delivery of active ingredients, with applications across multiple agricultural and industrial use cases. Commercial discussions with potential partners will be considered at the appropriate time as the patent process progresses.
Agform Sues Croda Over Alleged Theft of Trade Secrets
UPDATE: The complaint referenced below was filed in 2025 and subsequently withdrawn without prejudice. No determination on the merits has been made.
Agform’s Complaint alleges that Croda engaged in a pattern of wrongdoing aimed at improperly acquiring, using, and disclosing trade secrets related to Agform’s Envelop® technology — a proprietary, microplastic-free and biodegradable formulation platform designed for the encapsulation of volatile actives and the protection of crops and applicators.
A new research laboratory was opened at Southampton University Science Park to develop novel microplastic-free formulations, based on the Envelop® technology pioneered by Agform
Agform received a U.K. approval for Whip , a product containing diflufenican, for application on winter cereals in the autumn. Using Agform's novel technology, TransCel® the application rate was approved for use at half the rate of conventional formulations, without affecting efficacy The product offers an alternative method of grass and broad leaved weed control to cereal growers.
