A fungal root and crown disease (Gaeumannomyces tritici) of wheat, barley and other cereals that blackens roots and stem bases, causing stunted, prematurely ripened patches in fields known as whiteheads. It tends to build up in soil under continuous cereal cropping and typically declines after several consecutive years of wheat through a natural process called take-all decline, which is itself a well studied example of soil suppressiveness in plant pathology.
