Stem canker of brassicas, also known as blackleg is the most damaging disease of many Brassicaceae. The disease is caused by Leptosphaeria maculans (Desm.) Ces et de Not. and L. biglobosa sp. nov., Shoemaker & Brun, which coexist in plants and resulting in disease symptoms and decreased yield, quantity and quality of cultivated vegetables and oilseed rape. The paper presents taxonomic relationships between these coexisting pathogen species, describes particular stages of their life cycles, summarizes the differences between the species, and reviews methods for their identification.

PL

Sucha zgnilizna, potocznie zwana czarną nóżką jest najgroźniejszą chorobą roślin rodziny Brassicaceae. Wywołują ją dwa patogeny Leptosphaeria maculans (Desm.) Ces et de Not. i L. biglobosa sp. nov. Shoemaker & Brun, które wspólnie kolonizują rośliny i prowadzą do powstania objawów chorobowych, utraty plonu oraz jakości warzyw kapustowatych i rzepaku. W niniejszym opracowaniu przedstawiono przynależność taksonomiczną i pokrewieństwo tych gatunków, szczegółowo opisano kolejne fazy rozwojowe obu patogenów, wskazano na różnice międzygatunkowe oraz metody identyfikacji opisanych gatunków.
