About Lesson
  • The top rot begins with wilting and drying up of the tips of middle leaves of the whorl.
  • A decay that continues rapidly spreads downwards throughout the stalk and the affected plants soon droop.
  • Although it may spread along the plant to infect additional nodes, the bacteria do not usually spread to neighboring plants unless vectored by an insect.
  • Splitting the stalk reveals internal discoloration and soft slimy rot mostly initiating at the nodes.
  • Because the bacteria usually do not spread from plant to plant, diseased plants are quite often found scattered throughout the field.
