HAIL

 

To add insult to the injury of other weather-related cropping (and other) issues, hail danced across the area on Saturday, varying from none to light to severe.

                                                                                                       

To assess injury to corn and options to consider, see http://www.extension.iastate.edu/Pages/eccrops/hailcorn.html.

Post-emergence Corn Herbicides on Hail Damaged Corn

 

Many post-emergence corn herbicides have limits based on plant height and/or stage of development.  If parts of plants have been removed, the limits apply to what would have been there normally.

 

Injured corn plants will be under stress and may be more susceptible to herbicide injury, so applications should wait until the crop has had a chance to do some recovery, if possible.  Injured weeds may also be less susceptible to herbicides, but in many cases, the weeds are already larger (before injury) than what is prescribed on the herbicide label.  Unfortunately, there are not silver bullets for this situation.

 

If you have any questions, please feel free to contact the Iowa State University Extension Office.
