Abstract
- Foliar fungicide application on Western Australian faba bean crops can be safely delayed until flowering begins, even if chocolate spot is present at low levels earlier in the season.
- An alert system using in-crop monitors is being developed that might provide increased confidence in making fungicide application decisions – by supporting the decision not to spray.
- In high rainfall/risk areas the ‘alert’ system could need modification to account for extended periods of very high humidity and ‘discounting’ temperature.
- PBA Bendoc is rated ‘S’ for chocolate spot and might not be the best variety in high rainfall/high humidity regions. In these circumstances PBA Amberley would be a better choice.
