For many northern Wisconsin corn growers, the 2011 growing season came to an end sometime during the night of Sept. 14, says Joe Lauer, UW-Madison Extension corn specialist. Corn in many areas had not reached physiological maturity and was killed prematurely. Corn is killed when temperatures are near 32 F for a few hours, and when temperatures are near 28 F for a few minutes. For more, see Lauer’s blog.
