Wind and hail damage to pollination corn

Find guidance on how to manage damage from strong winds and hail when tassels are just starting to become visible or when corn has partially or completely been pollinated.

Damage can include loss of leaf area and stem bruising from hail stones, along with root lodging and stalk breakage from high winds.

What to do if your field gets damaged

Growers with damaged fields should contact their crop insurance agents as soon as possible. Some producers may even consider cutting the crop for silage. Corn silage from plants with few ears will likely be wetter and have higher nitrate levels than normal.

Because you’ll find the highest nitrate concentrations in the lower stalk, it’s best to cut such plants a few inches higher than normal.
