The Columbia lance nematode (Hoplolaimus columbus Sher) can cause significant yield suppression in cotton (Gossypium hirsutum L.) when it is present in the soil and inside roots. This study was undertaken to determine whether extracting nematodes from only the soil was sufficient to make accurate comparisons among treatments in cotton. We also studied the proportion of H. columbus present in the soil to determine whether that proportion varied among treatments at a single
