Rhizoctonia bare patch disease inoculum build-up in different cereal crops and varieties locations
Aims

To determine the variation in the build-up of Rhizoctonia solani AG8 inoculum between cereal crops wheat, barley, triticale and cereal rye and varieties in a cropping system.

Key messages

• A significant variation in the rhizoctonia inoculum build-up exists between cereal crops wheat, barley, triticale and cereal rye and their varieties. Inoculum build-up was generally higher in the barley varieties compared to that in other crops. Results are in general agreement with observations in other experiments in the Mallee and on calcareous soils in Eyre Peninsula.
• Differences in inoculum levels carried through summer and seen at sowing in 2016 suggest that farmers may select between cereal crops and their varieties to limit inoculum building during the cereal phase. However, non-cereal break crops are the best option to reduce the pathogen inoculum in a cropping system.
• Soil physical (compaction), chemical (organic C and nutrients) and biological (activity and composition) characteristics and seasonal (temperature and rainfall) factors can influence the growth of R. solani AG8 fungi and the severity of rhizoctonia disease.
