A mottling of the lower leaves becomes apparent, but disease symptoms progress up the plant as plants near maturity. Tissue between leaf veins become yellow, then brown,giving diseased leaves a mottled appearance. Diseased leaves eventually wilt, become
completely dry, and die. A blackening of the stems is often apparent, especially near the soil line. Infected plants are stunted and mature early or die before flowering. The vascular system of infected stems is brown to black when cut in cross section.
