Damage is usually in a circular pattern in the field. Plants nearest the strike will suddenly wilt and may die. Whole plants or individual leaves on plants in the surrounding area may also wilt. Some leaves will have black or shriveled midribs and veins. Areas of lamina may pucker because growth of the midribs or veins is reduced. The stalk may be hollow, or the pith may be disced with irregular separations. The pith remains white which differentiates lightning damage from black shank and hollow stalk.
