Eyespot & The Importance of T1 Sprays

Symptoms and diagnosis of eyespot

What situations favour eyespot?

  • Ploughing
  • Mild, wet spring weather
  • Varietal susceptibility
    • 30% of varieties on the Recommended List have poor ratings (4 or less) for eyespot

  • Heavy, moisture retentive soil
  • Second cereals
  • Eyespot is a hidden disease (until white heads appear or lodging occurs)
    • There are still frequent yield responses when it is controlled, even when incidence is moderate

It's easy to confuse early symptoms of eyespot with sharp eyespot and Fusarium spp. Often, all that is visible is a brown smudge on the leaf sheath at the stem-base. In early-sown crops eyespot lesions may penetrate one or two leaf sheaths, making identification more conclusive. Lesions caused by Fusarium spp. Later in the season eyespot symptoms become more distinct and appear as an eye-shaped lesion with a dark margin, usually below the first node. In severe attacks of eyespot, white-heads (“bleached” ears) are commonly seen scattered through the crop, later in the season these may become colonised by sooty moulds.
