This study examines the prevalence and characteristics of white rust and Alternaria leaf blight in mustard crops across different locations. Variability in white rust infection rates underscores the need for further documentation on pathogen dominance. Alternaria leaf blight progresses from circular spots to extensive lesions, with A. brassicae and A. brassicicola identified as key pathogens. White rust symptoms manifest as creamy pustules, often associated with downy mildew. Microscopic analysis reveals the presence of A. candida sporangia and H. parasitica conidia, contributing to the prevalence of white rust and downy mildew mixed infection.
