Monsanto began manufacturing DDT in 1944, along with some 15 other companies. This insecticide was used to kill malaria-transmitting mosquitoes, but it was banned in the United States in 1972 due to its harmful environmental impacts. In 1977, Monsanto stopped producing PCBs; Congress banned PCB production two years later. [37] [38]
