Trial location(s) Streaky Bay, SA
Rhizoctonia inoculum levels and rotations locations
Aims

To determine if disease suppression against rhizoctonia is achievable in an upper EP environment on a grey highly calcareous soil. It also assessed whether soil microbial populations can be influenced by rotation and fertiliser inputs in this environment.

Key messages
  • Canola and medic will reduce Rhizoctonia inoculum but only one year of cereal will result in high levels of Rhizoctonia inoculum again.
  • Disease suppression has not developed in this environment despite it happening within the same time frame in other environments.
