Options to manage soybean cyst nematodes

Unless you are a nematologist or paid really close attention in college classes, it’s likely that your introduction to nematodes was information about soybean cyst nematodes (SCN). These microscopic, thread-like worms form tiny cysts on soybean roots, and can cut into plant growth and yield.
 
Although many soybean varieties now have SCN resistance, SCN still accounts for significant soybean yield losses. Crop rotation is a commonly recommended control option, and it helps to a certain extent, but it does nothing to protect against the many other species of soybeanematodes that also feed on rotational crops such as corn. Another option for SCN protection is choosing a seed treatmentthat includes a nematicide, with activity against SCN infestation, and other nematode species, as well. 
 
Do you have SCN in any of your fields? How to you manage them?
