Impact of common root rot and crown rot on wheat yield – Tamworth 2015

Abstract

Key findings • A medium level of common root rot infection reduced the yield of LRPB Gauntlet[PBR] by 11% with a high level of infection resulting in 20% yield loss. • Crown rot infection had around double the impact on yield loss with a medium level of inoculum reducing yield by 23% and a high level of crown rot infection resulting in 41% yield loss. • Combined infection with both pathogens further exacerbated yield loss which equated to 31% and 52% with a medium or high level of inoculum of both pathogens, respectively.
