Abstract

The soybean cyst nematode (SCN) is an important, widespread soybean pest in Iowa that often goes unnoticed, particularly in years of adequate to excess rainfall. To date, SCN has been discovered in 84 of the 99 Iowa counties, and it is suspected to be present in many additional counties. The only consistent and reliable sign of an SCN infestation in the field is the presence of adult SCN females and cysts (dead females) on the roots of infected soybean plants. The adult SCN females and cysts appear as small, white- to yellow-colored objects, each approximately the size of a period at the end of a sentence.
