Lightning Injury

A circular patch of affected plants (3- 20 m or 10- 66 ft. in diameter) suddenly appears in the field.  Initially, leaves at the ends of branches will begin to droop, followed by wilting, and in severe cases, death of the plant.  One side of the stem may be caved in, like a furrow, down it’s length.  If the stem is cut, it will appear hollow, or have a ladder-like arrangement of tissue.  Plants toward the outer edge may show less damage.
