These are the first studies in highlighting Alternaria leaf spot pathogens and their populations on Australian rapeseed (Brassica napus), and their virulence levels within and between different Alternaria spp. Epidemiological studies, along with differential vulnerabilities of different plant ages, explain, for the first time, the disease epidemiology of A. japonica on Brassica spp. in current and predicted climates. Field studies demonstrated A. japonica causes more than 55% yield loss, similar yield losses as occur with A. brassicae. Noval and highly resistant varieties against A. japonica were identified, but there were only highly susceptible varieties found against A. brassicae.
