This research report of Steffen Noleppa (agripol – network for policy advice GbR) and Thomas Hahn (a-connect) investigates the socio-economic and environmental contribution of the Neonicotinoid technology to the European Union and the catalysing role it plays in modern agriculture. Seed treatment is one of the most advanced forms of crop protection, and NNi is highly efficient because of its targeted action and low application dose. It enables farmers to improve their productivity and profitability. Besides, the study reveals the impact to the various stakeholders if this technology was no longer available.
