dc.description.abstract Soybean cyst nematode (Heterodera glycines Ichinohe; SCN) is the most important pest of soybean (Glycine max L.) and also threatens dry bean (Phaseolus vulgaris L.) production, but knowledge of this threat is limited. Field studies were conducted between 2011 and 2014 near Rodney and Exeter, ON, in naturally-infested soil to determine the SCN tolerance of selected Ontario dry bean cultivars and efficacy of potential SCN controls including Bacillus firmus, Pasteuria nishizawae, fluopyram and spirotetramat. Cyst counts and root rot were evaluated at six weeks after seeding, and seed yield and the reproduction of SCN cysts and eggs were measured at harvest. Contrast analysis showed that Mesoamerican cultivars had lower cyst counts than Andean cultivars, and adzuki bean was the most susceptible market class. Bacillus firmus, P. nishizawae, fluopyram or spirotetramat had no measureable effect on SCN. Greenhouse studies are needed to confirm these preliminary field results. en_US
