Yellow Leaf Spot

Managing yellow leaf spot in stubble retained systems in Central West NSW

Locally specific guidelines and support for a proactive approach to disease management within retained stubble systems.

Key messages:

  • Stubbles carrying high loads of yellow leaf spot inoculum are the major source of crop infection. Decomposition or removal of stubble reduces inoculum.
  • Yellow leaf spot is most severe when successive wheat crops with low
    genetic yellow leaf spot resistance are grown on retained stubble.
  • Management of yellow leaf spot in CWFS districts should focus on
    disease identification and good agronomic practice.
  • Timely urea application may improve crop performance over a fungicide.
  • Don’t confuse yellow leaf spot with nutrient deficiencies, leaf tipping or frost damage.
