NC STATE UNIVERSITY Disease Name: Fusarium Head Blight Pathogen: Fungus. Fusarium moniliforme Symptoms: Disintegrated pith tissues. White mold on kernel or starburst inside pericarp. Conditions: Warm, moist weather shortly after
- pollination. More prevalent when plants are
subjected to stresses (such as dry weather) that result in early senescence and a reduction of sugar to roots and stalks. Inoculum Survival: Infected crop residue (seed, stalks), soil. Inoculum Dispersal: Soilborne hyphal fragments and spores. Infection occurs through roots. Management: Resistant hybrids. Full season hybrids tend to have more resistance than short season. Balanced soil fertility. Do not exceed recommended plant populations.

- 1. Starter Fertilizer with P – S – and Zn should be applied on
sandy ground where litter or waste has not been used. P and S should be applied to organic soils.
- 2. Sidedress N is critical – apply at least 60 lbs of N at sidedress
- 3. Total N rates of 120 lbs worked very well in 2012 and 2013
