Yellow leaf spot susceptibility trial locations

To evaluate the reported yellow leaf spot susceptibility ratings of 20 common wheat varieties

Key messages
  • Significant variation in yellow leaf spot susceptibility exists between varieties of wheat commonly grown on the Lower Eyre Peninsula and this is correlated with significant yield differences.
  • If sowing into stubble with a history of yellow leaf spot, it is important to make good management decisions to avoid yield losses.
  • Choice of variety has more impact on yield than does fungicide management strategy, and is likely to lead to greater profit.
