Managing 'take-all' and crown rot locations
Aims

To report on managing 'take-all' and crown rot.

Key messages
  • Incorrect identification could be costly as with Take all and Crown rot require different management.
  • Check the bases of plants for symptoms, don’t rely on whiteheads (which need not even be disease related).
  • Even where whiteheads are not present, significant yield losses can occur.
  • Know the risk of yield loss in your paddocks before sowing. For 2012 crops, this will mean sending summer/autumn soil samples to the Predicta B testing service for analysis.
  • The most effective management tool for both diseases is host-free breaks.
  • Where old cereal rows have medium to high inoculum levels, sowing between those old rows can reduce yield losses from these diseases, but only if the inter-row has low levels of inoculum.
  • When Take-all inoculum levels are medium to high, the best option is a 12 month break from hosts. If susceptible cereals must be sown, keep the paddock(s) weed free and sow the atrisk paddock(s) last in the cereal cropping program.
  • When crown rot inoculum levels are medium to high, the best option is a break from hosts (2-3 years may be needed). If cereals must be sown then barley is least likely to show yield loss, followed by oats and bread wheat. Do not apply excessive nitrogen early in the season.
