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.

Test rows stand in an otherwise empty field which cleared after drought conditions and extreme heat during pollination irreversibly damaged the crop in Carmi, Illinois, U.S., on Wednesday, July 11, 2012. The rows were left in the field so insurance adjusters can determine the extent of the crop loss at the plant's maturity. Photographer: Daniel Acker/Bloomberg
