Previously, most Fusarium root rot of dry edible bean was considered to be caused by Fusarium solani (Mart.) Sacc. f. sp. phaseoli W.C. Snyder & H.N. Hansen (Fsp). Recently, several reports of F. graminearum Schwabe (Fg) causing disease on below-ground tissues of dicotyledonous plants have been published. The objectives of our research were to: (i) determine if a pathogenic association between Fg and dry edible bean occurs under natural field conditions; (ii) test Fg isolates from dry edible bean to compare aggressiveness with an Fsp isolate; and (iii) evaluate dry edible bean genotypes for resistance to root rot caused by Fg and Fsp.
