Bayer AG Crop Science division (Monheim am Rhein, Germany; XETRA: BAYN; ~€23B Crop Science revenue 2023) invented imidacloprid in 1985 and co-developed clothianidin with Nippon Soda (licensed from Takeda Chemical). Imidacloprid is the best-selling insecticide in the world by value (~$1.1B annual sales) across foliar, soil-drench, trunk-injection, and aquatic-herbicide use patterns — including structural pest control (termite soil treatments, whitefly foliar sprays on vegetables) and vector control programs (mosquito/bed bug treatments in public health applications). Bayer manufactures imidacloprid and clothianidin technical grade at Dormagen and Leverkusen (North Rhine-Westphalia) and at Monheim R&D/production. Post-2018 EU outdoor ban, Bayer pivoted residual imidacloprid volume toward non-EU foliar markets (India, Brazil, US, Southeast Asia) and veterinary/companion animal applications (Seresto collar — transferred to Elanco 2020).
