Field corn plants with wilted and dying leaves, plants which would normally stand over 6-feet tall at this point in the growing season, stand in a dry field in Idaville, Indiana, U.S., on Friday, July 6, 2012. Corn prices jumped to a nine-month high of $7.13 a bushel on the Chicago Board of Trade yesterday and have surged more than 37 percent since June 15 as a crop-damaging drought in the U.S. Midwest shows no signs of abating.
