从美国伊利诺伊州大豆病株上分离的两个立枯丝核菌强毒力分离物61D-3和65L-2(ATCC 66489)被鉴定为融合群(AG)2-2的成员。在温室内接种每克土壤100μg鲜菌丝的接种水平下，可引起藜科、豆科和禾本科植物的冠腐病和根腐病。这两个菌株在贮藏2年后，几乎没有产生松散的厚壁菌核，并保持了对大豆的致病力.
Two highly virulent isolates of Rhizoctonia solani, 61D-3 and 65L-2 (ATCC 66489), from diseased soybean (Glycine max) plants grown in Illinois were identified as members of anastomosis group (AG) 2-2. They caused crown and root rot on inoculated plant species in the Chenopodiaceae, Fabaceae, and Poaceae at an inoculum level of 100 μg of fresh mycelium per gram of soil in the greenhouse. Both isolates produced few loose, thick-walled sclerotia and maintained their pathogenicity to soybean after 2 yr in storage (...)
