Tundu disease (yellow ear rot) of wheat caused by Clavibacter tritici is usually associated with Anguina tritici.
The disease was first described by Hutchinson from Punjab in India. Milne (1919) observed the disease incidence depended on mechanical injury to the plant parts by eelworms and that the bacterium could grow only on the excretion of the eelworms.
The 'tundu' disease is characterized by twisting of the stem, distortion of the earhead, and rooting of the spikelets with a profuse oozing liquid from the affected tissues. Hence, the name of the disease is yellow ear rot. The ooze contains masses of bacterial cells.
