Lightning kills or injures soybean plants in a circular pattern within the field. The spots are typically about 5 meters in diameter, but may be as large as 15 meters with clearly defined margins. The affected area does not expand over time. Few plants or weeds within the circle survive, but plants near the edges may show only slight injury. Plants on the edges may exhibit splitting of the epidermis, dieback of terminals, and separations in the pith. Stems may be blackened with dead leaves remaining attached.
