Crazy Top (fungus - Sclerophthora macrospora): Symptoms vary with time of infection and degree of colonization. First symptoms are excessive tillering, rolling, and twisting of upper leaves. The tassel proliferates until it is just a mass of leaves, hence the name crazy top . Leaves may also be stunted with yellow stripes. Flowering before plants reach the four- to five-leaf stage is usually a factor. Losses are usually confined to small areas. Avoid wet fields with poor drainage.
