Description: Systemic infection begins in leaf veins which turn reddish. Systemically infected stalks are stunted. The leaves are mottled and distorted.

The terminal bud may die, and the central portion of the stalk in the terminal bud region will be darkened or deeply discolored. Excessive numbers of ground suckers may develop.
