Head scab

  • Cause: Fusarium graminearum
  • Environment: Favors warm (75°-85°F), wet weather
  • Timing: Infection occurs two weeks before flowering and continuing through the flowering period.
  • Appearance: Look for premature bleaching of one or more spikelets of the immature wheat head. During humid conditions, white or pink fungal growth with orange spore masses may be seen on the bleached spikelets. Blue-black fruiting structures also can form, giving the head a scabbed appearance.
  • Risk: Damage to leaf tissues and decreased yield potential
