In 2002-2003, a nematode survey was conducted in the southernmost counties of Illinois. Species in eight nematode genera were detected in the survey with four genera having species considered to be important soybean pathogens. Populations of Meloidogyne incognita were detected in 6% of all fields surveyed in southern Illinois. Elite breeding lines and cultivars were evaluated for resistance to gall formation and reproduction by the nematode. Resistance was identified in several soybean genotypes.
