Growers of hail-damaged silage or grain corn are getting some bad replanting advice, according to Dan Undersander, University of Wisconsin extension forage agronomist.

Replanting corn ground to sorghum-sudangrass is the worst possible option this late in the season, he says, because the crop needs hot weather and won't produce significant tonnage before it’s killed by frost. A number of Minnesota, Wisconsin and northern Iowa cornfields were severely damaged or devastated by hail in late July.

Information to help producers make hail-damage decisions has been added to Iowa State University Extension’s Disaster Recovery Web site. To access the site, go to www.extension.iastate.edu/disasterrecovery/info/haildamage.htm.
