Profitable break crops for management of root lesion nematodes and Rhizoctonia solani AG8 locations
Aims

To investigate the most effective and profitable break crops in rotation with cereals (wheat) for growers with RLN and R. solani in the same paddock, a two-year (2018 & 2019) break-crop rotation trial was implemented in Dumbleyung and Grass Valley.

Key messages
  • Canola is not a break crop in paddocks if root lesion nematodes (RLN) and Rhizoctonia solani are both present
  • Weed free legumes, pulses and pastures are the best options where RLN and R. solani co-exist in a paddock
  • Cereals substantially increase RLN and R. solani levels while canola will also increase RLN
