Did you know2022
Sumitomo Chemical (Tokyo) was one of the key contributors to the development of the synthetic pyrethroid class of insecticides, building on research pioneered by Michael Elliott at Rothamsted Research (UK) in the 1970s. Sumitomo's proprietary alpha-cypermethrin and esfenvalerate compounds represent advanced-generation pyrethroids with improved selectivity and reduced environmental persistence. This Japanese company's contributions to agricultural chemistry — producing compounds used in malaria prevention and crop protection globally — are rarely recognized in public discussions of Japanese industrial competitiveness.
