CropTrials GmbH is an independent private company for agricultural field research and development of agrochemical products. It is the successor organisation of Versuchswesen Pflanzenschutz, which was founded in 1990. CropTrials GmbH provides studies to evaluate the efficacy and the crop safety of pesticides. Furthermore, it offers residue studies, soil dissipation and accumulation studies as well as rotational crop studies.
