Yellow leaf spot yield loss experiment – southern NSW 2015 locations
Aims

This experiment examined the effect of yellow leaf spot (YLS) on yield in three wheat varieties of differing resistance in southern NSW.

Key messages
  • Fungicide reduced disease levels in all varieties, but failed to eliminate the disease completely.
  • Observed differences in disease levels were broadly in agreement with published variety resistance ratings.
  • Yield losses were observed in the more susceptible varieties due to early disease development.
  • Low disease levels from an early stage can cause yield losses.
  • Variety selection will always play an important role in managing disease in high risk areas.
