Syngenta Group (ChemChina)
Syngenta Group (Basel, Switzerland; wholly owned by ChemChina / Sinochem Holdings since 2017 at $43B — the largest Chinese acquisition of a foreign company at the time) invented thiamethoxam (Actara foliar/soil insecticide; Cruiser seed treatment) and is the primary global producer. Actara and Engeo Pleno (lambda-cyhalothrin + thiamethoxam) are the leading foliar neonicotinoid products for whitefly, leafhopper, and aphid control on vegetables, citrus, and cotton globally. Syngenta also produces acetamiprid (Assail) for foliar use. Manufacturing at Huddersfield UK (primary thiamethoxam) and Schweizerhalle/Basel Switzerland. ChemChina's 2021 merger with Sinochem created a combined entity (~$150B revenue) that includes ADAMA generic agrochemicals — giving a single Chinese state-linked conglomerate both the branded thiamethoxam franchise and significant generic neonicotinoid capacity.
