Commercial rust in Yitpi wheat locations
Aims

To Investigate strategies for Managing Stripe Rust in WA

Key messages
  • In the absence of stripe rust but the presence of leaf and stem rust and powdery mildew, an integrated fungicide strategy is critical for maximising yield and grain quality.
  • Early application of fungicide (e.g. seed treatment or in-furrow) alone is insufficient to optimise grain yield and quality.

Other trial notes

MAKING IT COMMERCIAL PRACTICE: The use of an integrated fungicide strategy, such as in-furrow fungicide or Jockey at seeding, followed by the application of foliar fungicides at Z39 maximises yield and quality. Utilising early fungicide application to minimise the early development of disease and the subsequent control later in the season with foliar applications of fungicides appears to be the most effective use of fungicides. Allowing disease to develop then trying to control it in the crop is ineffective as adverse effects on potential yield of the early disease can not be overcome with late applications of foliar fungicides. Multiple applications of foliar fungicides may be warranted in high-pressure disease years. An earlier foliar application may improve later season control of disease and result in higher yields and better quality grain.
