The fungus behaves very much like Fusarium in its survival and life
history. It is both soil and seed-borne, It infects seedlings as they emerge,
occasionally producing a seedling
blight . More usually it infects roots of seedlings, allowing the plant
to survive. Leaf spotting and stem-base infections produce splash-borne spores
which can be carried to emerged ears resulting in seed infection.
