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.

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.
