Description: Head
scab is identified as dead, bleached out florets on affected heads scattered
throughout the field. Generally only a portion of the florets die whereas other
florets on the head remain green. During periods of high humidity, salmon?pink
colored spores form on the margin of glumes of individual florets. Seed from
affected heads are shriveled with a white to pinkish coloration.
Location: Throughout Ohio.
Time of attack: Wheat plants are only susceptible during the flowering stage
of the plant (late May to early June). Wet warm weather during this time generally
means high disease levels.
Management:
· Resistant hybrids
· Crop rotation
· Do not plant wheat after corn
· Till residues
