New Options for Soybean Cyst Nematode Resistance

Talk to your AgVenture Yield Specialist about your SCN management strategy.

Most soybean cyst nematode (SCN) resistant varieties have the same source of resistance, PI88788. While has provided two decades of resistance to SCN, these microscopic parasites are adapting and finding a way around its resistance. More and more, nematodes are successfully laying eggs on roots, and increasing in number. This is having a significant negative impact on soybean yields.

New breeding lines are providing some growers with options for resistance management including those originating from Peking lines. Nematodes do not possess the genes that allow them to feed on those lines.

Talk with your AgVenture Yield Specialist about your SCN management strategy and resistant lines today.

AgVenture recommends actively managing SCN populations. Start by sampling fields to know the population densities of SCN present. While SCN testing is commonly done in the fall, last fall prevented many growers from taking samples. Spring sampling can still provide you with important benchmarking information. Other management tactics include rotating to non-host crops and rotating resistant varieties. For specifics on SCN resistance and management, visit: https://www.thescncoalition.com/.
