Management of soilborne Rhizoctonia disease risk in cereal crops locations
Aims

To improve long term control of Rhizoctonia by increasing the understanding of the interactions between disease inoculum and natural soil suppressive activity and to improve the prediction and management of the disease.

Key messages
  • Grass free canola and pasture reduce Rhizoctonia inoculum levels and can provide effective control of Rhizoctonia for a following cereal crop.
  • The cereal yield benefits from previous rotation crops were higher in 2011 compared to 2010 as a result of higher Rhizoctonia inoculum levels at sowing in 2011.
  • Cereals (and grasses) are the main hosts for Rhizoctonia and result in the rapid build up of inoculum.
  • Rhizoctonia inoculum is reduced following rainfall after crop maturity but levels can recover during dry periods over summer/autumn.
  • Following a wet summer (multiple rainfall events), levels of Rhizoctonia inoculum can be reduced from high risk to low risk.
  • Rhizoctonia inoculum levels at sowing were significantly lower in cultivation treatments compared to notill however in the trials to date, the decline in inoculum with cultivation has not been sufficient to provide a yield benefit.
