Soybean Cyst Nematode Fact Sheet
A revised Soybean Cyst Nematode fact sheet from the University of Minnesota Extension Service has just been released. This document covers the life cycle, symptoms and sign, diagnosis, soil sampling, and management strategies for the Soybean Cyst nematode.
The printed publication can be ordered by calling either (612) 624-4900 or (800) 876-8636.The cost is $3.00/copy + shipping and handling.
Low levels of infection can remain undetected for some time as no diagnostic above ground symptom exists. Stunted, chlorotic, vigorless beans with reduced root systems and few nitrogen nodules are typical of low infection levels in high fertility sites. Egg numbers do increase and symptom severity increases, reducing soybean yields. Carefully dig and examine roots for white to tan females containing eggs any time after late June through September. The cysts are spread by soil movement from equipment, or with water or wind. Birds can carry the cysts considerable distances. Most farms have some level of infestation.
