CORN CRUMBLES: Corn futures fell sharply after traders worried that a drop in export sales last week was the beginning of a new trend. Corn for July delivery settled at $5.7950 Friday, down 22 cents.

WEAK EXPORTS: Export sales of corn fell below 100,000 tons last week, said John Sanow, market analyst at Telvent DTN, a commodity information firm in Omaha. That’s the worst showing this year.
