Foliar symptoms on plants with Fusarium crown and root rot include yellowing along the margin of the oldest leaves, followed by necrosis. Dry brown lesions develop in the cortex of the tap or main lateral roots. A necrotic lesion may also develop on the surface of the stem from the soil line to 4 to 12 inches (10?30 cm) above it. Internally, a reddish brown or chocolate-brown discoloration extends no more than 6 to 12 inches (15?30 cm) above the soil line. Infected plants may be stunted and wilted, and older plants may die.
