Better prediction and management of Rhizoctonia disease in cereals 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 disease.

Key messages
  • Inoculum can change dramatically throughout the year.
  • Inoculum is concentrated near the surface of field soils (top 5 cm).
  • Cereals are the key host for rapid build-up of Rhizoctonia solani AG8 inoculum.
  • Soil microbial assessments have been strongly associated with changes in Rhizoctonia infection, especially seasonal and site differences.
  • The importance of Rhizoctonia infection on crown roots in modern cropping systems may have been underestimated.

Event Date Type Effect
Mouse damage

The trial was sown again on 7 June 2010 into reasonable moisture but mice damage resulted in the cereal plots being sprayed out and resown on 29 June. These plots were also harrowed to remove the furrows and make it harder for mice to find the grain.
