varieties when SCN numbers are low to slow down the adaptation of SCN to resistant varieties. “Growing resistant varieties year on year (continuous cropping) promotes resistance breakdown. Resistant varieties need to be used with a biosecurity protocol to avoid bringing resistant SCN to fields. Use a smart rotation, avoiding edible beans in rotation, and good weed control because weeds can be alternate hosts.” New information on SCN could be coming to us soon, and we could be seeing more resistant varieties in the Western Canadian market. “Recent advances have been made in understanding the biochemical and molecular interaction of SCN with soybean and new resistant genes have been found. Likely advances will be coming soon.” Soybean damage due to SCN is frequently misdiagnosed. The only way to get a reliable diagnosis is through a professional diagnostic laboratory. Reduce your risk of loss by submitting soil samples for professional analysis.
SOYBEAN CYST NEMATODE IS MARCHING IN OUR DIRECTION AND IS INEVITABLE You can delay and lessen the damage: • Keep your machinery clean • Keep tires and footwear clean • Know your field risk areas • Dig plants to scout fields • Weed suppression • Avoid tight rotations and don’t rotate with edible beans and peas • SCN soil test • Use resistant varieties • Bird suppression. 29
