Fusarium crown and root rot symptoms start with yellowing on the margin of the leaves followed by severe necrosis of leaves. The disease can cause rapid wilting of plants.
The symptoms are usually noticed as yellowing of younger leaves followed by older leaves. Wilting follows and plants may recover from wilting during night but will completely wilt or remain stunted.
The cut stem of the infected plants show internal discoloration (left). This is not a definitive symptom for the disease. Necrotic sections from the base of the plant may have orange spore masses (right).
