The European Commission, on advice from the European Food Safety Agency (EFSA), has banned two pesticides: chlorpyrifos and chlorpyrifos-methyl - organophosphates used as ingredients in a number of insecticides.
Chlorpyrifos is manufactured primarily by Corteva, formerly Dow Chemical and renamed Corteva following its merger with DuPont in June 2019). It has been on the market since 1966 and is currently in use in some 80 countries.
