Managing rust

By planning ahead to manage rust it is possible to minimise its cost to your business. It is important that growers choose a strategy that is appropriate to their situation, and follow it during the growing season.

Step 1:

Make a strategic variety selection

Step 2:

Management

Step 3:

Communicate – rust is a social disease!

Step 4:

Submit a sample – it’s for the industry good!

Step 1: Make a strategic variety selection

  • Check your variety’s rust resistance ratings
  • Understand all-stage vs adult plant rust resistance as this impacts your crop management e.g. chemical control, monitoring, etc
  • Consult with your agronomist and/or plant pathologist for support
Check your ratings

Step 2: Management

  • Remove the green bridge at least four weeks before seeding
  • Consider using an in-furrow fungicide or seed treatment to protect early growth especially in susceptible varieties
  • Monitor crops at seven to 10 day intervals from early stem elongation if rust has been reported in your area
  • Apply foliar fungicide, either as preventative or as soon as rust is detected according to label instructions

Step 3: Communicate

  • Rust is a social disease
  • If you have a rust outbreak, let your neighbours know
  • Follow basic biosecurity measures, e.g. clean clothes and boots and washing down machinery to limit the risk of spread
  • Let your agronomist and state plant pathologist know if you find rust
Let us know

Step 4: Submit a sample

  • It’s for the industry good!
  • The Australian Cereal Rust Survey is free.
  • Reply paid envelopes are available.
  • Your sample can help identify new rust pathotypes or the spread of the disease.
  • Play your part in national rust management

Rusts are caused by parasitic fungi which reproduce and thrive on green plant tissue. The fungus releases airborne spores which are spread readily by the wind over large areas in a short time.

Rust spores can also spread on clothing, footwear and machinery. If a rust spore comes in contact with susceptible plant tissue, it penetrates and infects individual plant cells.

Biosecurity is vital in managing rust. Stop the spread of rust disease by being responsible.
