A 4-yr study conducted on two soil types showed that lesion nematode numbers were significantly higher in the roots of field corn grown in moldboard-plowed plots than in nontilled plots. The population increase in chisel-plowed plots was intermediate between those in moldboard-plowed and nontilled plots.
