Description:
This bacterial soft rot usually first appears following topping and suckering. Although the bacteria can invade the stalk through any wound, they usually enter through the break at the top. The pith rapidly turns brown and collapses in a watery rot. A foul odor is evident as the stalks become hollow. Leaves adjacent to the rotting pith will wilt. The rot may extend into the leaves through the midrib. The midribs turn black and the leaves droop. If infected leaves are placed in the barn, soft rot may continue to develop as barn rot.
