Rhizoctonia is an important disease of cereals in southern and western growing regions, especially in low rainfall areas. Losses have been estimated at about $15 per hectare for wheat and $12 per hectare for barley in the southern region. 

Unfortunately, fungicide control of rhizoctonia has proven to be difficult, often with mixed results with seed treatments.  

In February 2025, we sat down with Blake Gontar from the South Australian Research and Development Institute to talk about a previous GRDC investment that showed streaming fungicide above and below the seed was an effective way to protect cereals from rhizoctonia and get the greatest yield responses.
