Alternaria brassicicola is a fungal necrotrophic plant pathogen that causes black spot disease on a wide range of hosts, particularly in the genus of Brassica, including a number of economically important crops such as cabbage, Chinese cabbage, cauliflower, oilseeds, broccoli and canola.[1][2][3] Although mainly known as a significant plant pathogen, it also contributes to various respiratory allergic conditions such as asthma and rhinoconjunctivitis.[4] Despite the presence of mating genes, no sexual reproductive stage has been reported for this fungus.[5][1][3] In terms of geography, it is most likely to be found in tropical and sub-tropical regions, but also in places with high rain and humidity such as Poland.[3] It has also been found in Taiwan and Israel.[6][7] Its main mode of propagation is vegetative. The resulting conidia reside in the soil, air and water.[3] These spores are extremely resilient and can overwinter on crop debris and overwintering herbaceous plants.[3]
