Fungicides for strategic and tactical control of wheat leaf diseases in central-west NSW locations
Aims

To assess the potential for yield and quality responses from controlling Stripe Rust and Yellow Leaf Spot (YLS) in central-western (CW) NSW.

Key messages
  • H45 proved far more susceptible to stripe rust than Diamondbird in 2004.
  • With the dry conditions of 2004, when yields were higher (2-3 t/ha) stripe rust infection significantly decreased yield in H45 by 16%-17%. Grain quality effects were also recorded at the site with the highest level of infection.
  • Jockey seed treatment provided some residual control of stripe rust at two out ofthe three sites.
  • Foliar fungicides proved very effective at reducing stripe rust infection.
  • Only the combination of seed applied + foliar fungicide resulted in a significantlyhigher yield and quality than the nil treatment with H45 wheat.
  • Yellow leaf spot had no effect on yield or quality of the susceptible varietyDiamondbird.
