Beware of Harmful Hail on Corn

Hail can be an extremely harmful force on corn crops in the mid-to-late growth stages.

When you get mid-to-late season hail with plants in the early growth stage, it will usually have minimal effects on the potential yield of that crop. However, in the later growth stages, hail can cause damage in a number of ways including:

  • The growing point can be ruined.
  • Leaf area can be reduced through shedding and stripping.
  • Stalks and ears can be bruised by hail stones.
  • Wounds can open the plant for fungal disease development.

With hail comes increased weed pressure. The two main weeds Western KS sees are kochia and Palmer amaranth. TJ Binns, agronomy service representative, says Palmer amaranth is the weed they are working to manage most at the Scott City, KS,  Grow More™ Experience site this season.

In the case of hail damage to corn in the later growth stages, we recommend growers either aerial apply or chemigate Dual II Magnum® herbicide to add a new layer of residual herbicide on the ground.

Growers can also simply try and let the corn grow out of the damage, and supplementing time with the use of fungicides to help the plant through that stress is common.

  • Trivapro® fungicide contains preventive and curative control of rusts, leaf spots and blights and helps boost corn and wheat yield potential under high or low disease pressure.
  • Miravis Neo® fungicide combines 3 powerful ingredients for broad-spectrum disease control and plant-health benefits for corn and soybeans.
