IES Ltd is highly experienced in conducting various kinds of metabolism studies, including the identification of unknown metabolites.


Our crop and animal metabolism specialists can support your product registration needs thanks to their years of experience within the industries. By performing metabolism studies on a wide range of crops or in feeding studies, we can verify the safety and effectiveness of your products. To additionally support your registration needs, we also offer bespoke in vitro studies for testing pharmaceuticals, cosmetics, plant protection products and other biocides.

Plant Metabolism/Metabolism in Rotational Crops

Studies on metabolism in crops or rotational crops are performed to elucidate the degradation pathway of active ingredients and to identify possible metabolites. IES Ltd offers metabolism studies with a wide range of crops, including grapes, oilseed rape, rice, wheat, corn and many others, covering all categories of crops required to be tested. At IES Ltd, plant metabolism studies are carried out either in the greenhouse in compartments with controlled temperature and humidity or at a purpose-designed outdoor station under natural environmental conditions.

Post-harvest Metabolism

Studies on post-harvest metabolism in crops are designed to elucidate the degradation pathway of an active ingredient upon post-harvest application of a plant protection product. The metabolic pathway is determined under specific controlled storage conditions.
