LONDON - EU antitrust authorities will decide by July 28 whether to allow the $130 billion merger of U.S. chemical company Dow Chemical Co <DOW.N> and its rival DuPont <DD.N>, one of several large agribusiness deals.


The companies requested approval on Wednesday, according to a filing on the European Commission website.


The EU competition enforcer can approve the deal with or without concessions or it can open a full-scale investigation of about five months should it have serious concerns about the merger's impact on consumers and rivals.


DuPont and Dow hope to close the deal around October-November. The U.S. Department of Justice is also examining the proposed merger.
