Rhizoctonia

Key points

• Management of Rhizoctonia requires an integrated approach to reduce inoculum and control infection and impact on yield.
• Rhizoctonia inoculum levels will be greatest following cereals, particularly barley.
• Grass-free canola is the most effective.
• But legumes can also help reduce inoculum loading.
• Disturbance below the seed at sowing promotes rapid root growth away from the Rhizoctonia and disrupts hyphal networks. The ideal depth is 5-10 cm.
• Fungicides applied through in-furrow liquid banding can provide useful suppression of Rhizoctonia disease.
• Herbicides that slow root growth can exacerbate the problem.
