MAIZE :: MINOR DISEASES :: BACTERIAL STALF ROT

Bacterial Stalk rot - Erwinia dissolvens
Symptoms
The basal internodes develop soft rot and give a water soaked appearance. A mild sweet fermenting odour accompanies such rotting. Leaves some time show signs of wilting and affected plants topple down in few days. Ears and shank may also show rot. They fail to develop further and the ears hang down simply from the plant     

Symptoms

 Disease cycle
Borer insects play a significant role in initiation of the disease. The organism is soil borne and makes its entry through wounds and injuries on the host surface. The organism survives saprophytically on debris of infected materials and serves primary inoculum in the next season.
