Brassica is one of the major sources of protein and oil for humans. It also serves as a promising source of allelochemical to control a variety of soil-borne pests. Various phytopathogens including bacteria, fungi, nematodes and viruses cause significant yield losses in storage and field conditions. The major fungal diseases are Alternaria leaf spot and blight (Alternaria spp.), Anthracnose (Colletotrichum spp.), Downy mildew (Peronospora parasitica), Powdery mildew (Erysiphe cruciferarum), Sclerotinia stem rot (Sclerotinia sclerotiorum), White rust (Albugo candida), Wilt (Fusarium spp.), Leaf spot (Leptosphaerulina brassicae, Cercospora cheiranthi), Damping-off (Pythium spp.), Clubroot (Plasmodiophora brassicae), Black leg (Leptosphaeria maculans). They are some of the most detrimental fungal diseases which causes huge crop loss including decrease in quantity, quality and market value. This review paper reveals the symptoms and management strategies against important fungal diseases affecting Brassica.
