Effective management of parsley summer root rot (VG13101)

What was it all about? 

Parsley summer root rot (SRR) affects all parsley-growing regions of Australia, and can lead to crop losses of up to 100 per cent. This study looked at the causal pathogens of SRR and developed an understanding of the disease’s epidemiology, particularly in relation to environmental conditions and practices. It also looked at integrated disease management strategies for the disease.

Research from this project confirmed that Pythium sulcatum is the most important cause of parsley SRR. This knowledge means growers can now apply more appropriate and effective management strategies targeting the pathogen. It was also found that longer crop rotations are needed in soil-based parsley production systems, particularly on farms where other apiaceous crops are grown.
