What to do with downed corn?

John Walter 07/12/2011 @ 12:14pm

After a “massive windstorm” hammered property and cropland across the Corn Belt, farmers will be watching their fields anxiously as an already deteriorating corn crop struggles into pollination.

The storm reached near-historic proportions in some areas. “The National Weather Service in Des Moines is calling the wind event ‘the most widespread and damaging one to affect central and east central Iowa since 1998’ and estimated winds from the storm at anywhere from 80 to 110 miles per hour,” Freese-Notis Weather reported on Tuesday.

Jim Fawcett, Iowa State University Extension agronomist, wrote: "There is likely over 100,000 acres of corn [in Iowa] that is flattened, in addition to thousands of trees snapped off, grain bins blown over, and farm buildings destroyed."

On Twitter, Brian Corkill, a Henry County, Illinois, farmer reported from his travels west:  “Some of the worst down corn I have ever seen [is] from State Center, Iowa, east 10 miles along US Highway 30.”

He added, “It is sickening just before pollination.”

Karen Corrigan, an independent agronomist based in central Illinois, reported  that farmers around the Midwest today are asking “lots of questions on what to do with down/flat corn.”

“There is a fair amount of downed corn in eastern Iowa, northwest Illinois, then across northern Illinois and southern Wisconsin, mostly north of I-80,” she said. “Seems like about 20% is flat from those I've talked to.”

Management tips

Corrigan offers several management tips for farmers dealing with down corn:

  • Look for signs of recovery. The downed corn in many areas has somewhat straightened overnight.
  • Fungicides on this recovered corn will help to fend off rot on the damaged stalks.
  • Wait until 80% silking before spraying fungicides. Fields are uneven in their growth and you do not want to chance ear deformation with too early of an application.
  • Do not spray fungicides this week. Most fields in these areas are within a week of tasseling or just beginning tassel. This is the absolute most risky time to spray fungicides due to potential ear deformation.
  • Fields that are flat and do not show good signs of recovery within the next week may be lost. Stalks may be broken or kinked disrupting plant growth. Pollination can also be minimal if silks are covered with leaves. Carefully assess the field and its chances before spending money.

Jim Doolittle, an agronomist in southeastern Wisconsin, surveyed his area and walked damaged fields with a customer this morning, finding some green snap and leaning corn, but not “anything that is completely flat.”

Wind Blown Corn stands right back up when "Atomic 07/16/2011 @ 4:54pm Early in the morning on July 9th, in 2008 corn fields in parts of North Carolina were subjected to high blown winds from a violent thunderstorm. Farmers were distraught and thought they had lost their crops after much of the corn was down,twisted and messed up.But two days later,on July 11th, farmers were pleasantly surprised to see that their corn (sprayed with Atomic Grow) had straightened back up and wasn't bowed.
