Trucks deliver supplies of newly harvested wheat grain to a storage depot operated by Kuban Agroholding, a unit of Basic Element Co., in Ust-Labinsk, Russia, on Monday, June 27, 2016. Russian wheat-export prices dropped to a six-year low last week as prices in major competitors such as the U.S. and France fell and harvesting of a bumper crop was about to start.
