First Report of Alternaria Black Spot caused by Alternaria alternata on Brassica carinata in South Dakota
During July 2016, Brassica carinata planted in experimental plots near Brookings, SD (44°18′37″ N, 96°40′25″ W), were observed with black spots (∼2 mm diameter) on the leaves and stems (average disease incidence ∼40%). Leaves and stems of five diseased plants were cut into 5 mm pieces, surface-sterilized, and plated onto potato dextrose agar (PDA). The PDA plates were incubated for 5 days at 25°C in the dark.
