Wheat Jumps Most in Three Months on U.S. Freeze Threat

Wheat jumped the most in three months on concern that a freeze will damage winter crops from South Dakota to Arkansas, eroding prospects for exports from the U.S., the world’s top shipper. Corn rose, and soybeans fell.

Temperatures as low as minus 7 degrees Fahrenheit (minus 22 Celsius) from Nebraska to Illinois and less than 10 degrees Fahrenheit through the lower Mississippi River Valley risk harming some winter wheat, World Weather Inc. said in a report. Colder weather next week may damage as much as 25 percent of the Midwest crop and 10 percent of plants in the Great Plains unprotected by snow cover, MDA Weather Services said.
