Hail Damaged Wheat: Two Week Followup

May 20, 2010 at 6:40 pm

On May 5, 2010 a hailstorm came through parts of Northwest Ohio and damaged soft red winter wheat in very early heading stage.  At this stage, the concern is assessment of the flag leaf and damage to the wheat head.  Initial assessment on May 7 revealed that 50-80% of flag leaves had been shredded or stems/leaves bent.

I revisited the field on May 20, 2010 and the bent flag leaves are dying. Even though some of the flag leaves were not torn/shredded, they were bent from the hail and are not recovering.

Up close examination shows that the sheath, approximately 0.75″ below the flag leaf, has been torn. This ultimately led to the death of the flag leaf.

I am working with the grower to get a harvest yield assessment. The field may yet get destroyed, but we will leave a small area to take to yield.

I’ll update this post in mid-July with some yield data… stay tuned.
