First Report of Brown Stem Rot of Soybean (Glycine max) Caused by Phialophora gregata in South Dakota
During late September 2010, soybean (Glycine max L.) plants exhibiting interveinal leaf necrosis and internal stem browning were received from Brookings (44°17.915′ N, 096°55.393′ W), Aurora (43°41.540′ N, 098°34.195′ W), and Hand (44°29.407′ N, 099°00.464′ W) counties for diagnosis. Isolations were made from the margins of the stem lesions by plating small pieces (5 mm) on a semiselective medium (GBA, Mengistu et al. 1991) amended with 0.02% streptomycin sulfate, followed by single-spore culturing and incubation at 20°C in the dark for 7 days.
