Maize 85 Northern Corn Leaf Blight

15 September 2023
Read PDF Online

This Maize update provides guidelines for reducing the risk of maize yield losses caused by Northern leaf blight (Exserohilum turcicum).

Key points

  1. Northern leaf blight (NLB) is a serious foliar disease of maize in New Zealand and can lead to yield losses of up to 50%.
  2. NLB overwinters in surface residue; burying residue reduces disease risk.
  3. Wet, mild weather is required for spread.
  4. The later the disease appears, the lower the yield loss.
  5. Use of resistant hybrids is recommended.
  6. Fungicides may be useful on susceptible hybrids to prevent early infection.
