Abstract: Soybean cyst nematode (Heterodera glycines Ichinohe; SCN) is a parasite that is a major pest of soybean (Glycine max (L.) Merr.) production worldwide and impacts dry bean (Phaseolus vulgaris L.) as well. Black (cv. Zorro) and kidney (cv. Red Hawk) bean seed were treated with two rates of biological (Pasturia nishizawae and Bacillus firmus) and chemical (fluopyram) nematicides in a controlled environment (27oC and16:8 h light:dark) for 30 days. Kidney bean was more susceptible to SCN than black bean. B. firmus + fluopyram reduced cyst numbers on both black and kidney beans with a clear rate response. In a second study, B. firmus at one rate and fluopyram at three rates were tested alone and together on two kidney beans (cv. Red Hawk and Dynasty). The seed treatments impacted SCN at all life stages, but the response was inconsistent over products and rates.
