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.
