Workflows for detecting fungicide resistance in net form and spot form net blotch pathogens.

The workflow and PCR assays designed in this study have been demonstrated to efficiently screen P. teres collections for both phenotypic and genetic resistance to DMI and SDHI fungicides. The distribution of reduced sensitivity and resistance to DMI and SDHI fungicides varied between regions in south-western Australia, suggesting the emergence of resistance was impacted by both local pathogen populations and disease management programs. The knowledge of fungicide resistance in regional P. teres collections will be important for informing appropriate management strategies. This article is protected by copyright. All rights reserved.
