There is still time this spring to check fields for the presence of soybean cyst nematode (SCN) before planting starts. This nematode is widespread throughout much of Iowa. However, soybean cyst nemadote infestations can go unnoticed because obvious aboveground symptoms may not be visible for many years after the introduction of the pest into the field. Early detection of soybean cyst nemadote infestations, when population densities (numbers) are still low, is very important. It is much easier to keep low population densities of soybean cyst nemadote in check than to try to decrease high population densities.
