Abstract

These studies are the first to demonstrate the phenotypic and phylogenetic patterns of N. capsellae pathogenicity, in response to 2015-16 isolates as compared with 2005 isolates. Epidemiological studies determine for the first-time role of climatic factors. Field studies demonstrated that N. capsellae causes upto 24% of yield losses. Present studies are also first to highlight the impact of herbicides on B. napus pathogens (N. capsellae, A. brassicae, A. japonica and H. brassicae) in relation to herbicide tolerant rapeseed. Finally, studies involving multi-pathogen interactions between these afore four pathogens have, for the first time, highlighted the unrecognised significance of pathogen-pathogen interactions.
