Managing stripe rust in a high-pressure season

Managing stripe rust in a high-pressure season

Published: 2 Jun 2023

In 2022 wheat crops were placed under greater stripe rust pressure than had occurred for many years. Many growers discovered a ‘business-as-usual’ approach was not sufficient to protect crops of susceptible varieties.

This publication 'Managing stripe rust in a high-pressure year' captures the experiences of eight growers across NSW, Victoria and Queensland and the management practices they used to get on top of the challenge. Some of their top tips included:

  • choose a more resistant variety
  • manage the green bridge to reduce the carryover of rust inoculum between seasons
  • use seed or fertiliser-applied fungicide to provide early season control
  • monitor crops to detect infection as early as possible
  • use fungicides as a protectant when stripe rust is first detected, do not rely on it for control
  • use the StripeRustWM App to plan fungicide applications
  • send rust-infected leaf samples for identification.
