Columbia lance nematode

Hoplolaimus columbus

Crop rotations with non-host crops or non-host cover crops is effective.
Since there are many weed hosts and the nematode can survive in dry soil for several years, fallowing a field to reduce the pest may be ineffective.
A shallow hardpan often restricts roots to upper 6 inches of soil and reduces plant tolerance.  Subsoiling and fumigation increases yield dramatically. Subsoiling and destruction of restrictive soil layers allows greater access to water and nutrients and can offset nematode damage.
