Ernest Barnes, a wheat farmer from Kansas, filed a civil lawsuit against Monsanto alleging gross negligence after unauthorized genetically modified wheat was found in an Oregon field, causing wheat export futures markets to plummet. Japan and South Korea announced they would cease wheat imports from the US in the wake of the discovery, spurring some of the downward movement in the market. Monsanto developed and planted Roundup-resistant wheat between 1998 and 2005, but destroyed the crops and cut the program after finding no market interest in GM wheat.
