Bacterial spike blight in wheat
Wheat spikes showing symptoms of bacterial spike blight, or yellow ear rot (Rathayibacter tritici). The disease produces a yellow exudate on the spikes is, which turns white when dry. Often the spikes and necks will emerge as a distorted, sticky mass. The early leaves may also be wrinkled or twisted.
