Affected plants are stunted, yellowed, have fewer tillers and die prematurely.
Prematurely killed plants have bleached out heads or white heads that appear in contrast to the green heads of healthy plants. Diagnostic black, scurfy, mold symptoms occur on roots and lower stems. Take-all may occur anywhere in Ohio. Fields with quackgrass infestations or fields planted back to wheat with no rotation are likely problem fields. Blackening of root systems can be detected in late May and June.
