The first symptoms appear as curving, yellowing, and/or die-back of leaves, beginning at the tips and developing downward. Wilt may also occur. Red-brown discoloration and rot will develop at the root-basal plate margin, and stems and bulbs will develop reddish or reddish-purple discoloration as the fungus moves up from the plate and into scales. Bulb tissue will appear brown and watery when cut open. White fungal growth may develop on the stem plate or between affected scales. Roots will eventually rot.
