3 Causes of Green Snap in Corn

Green snap, also called brittle snap, occurs when corn is in the vegetative state between V5 to V18 and strong winds cause stalk breakage at or below the growing point of the plant. Plants broken by green snap will not produce grain.

Corn that has reached V5 (5 leaf collars) is at or above the soil surface, making it vulnerable to green snap. During the rapid growth stage the internodes of the corn plants are elongating at a fast pace and new leaves can emerge every two days. As more leaves emerge, the plants are increasingly susceptible to experiencing wind and stalk breakage.
