Interaction ofpra tylenchus scribneri and helminthosporium pedicellatum in the etiology of corn root rot

  • 15 Accesses

  • 1 Citations


In experiments with both sterile and non-sterile natural soil,Pratylenchus scribneri interacted, perhaps synergistically, withHelminthosporium pedicellatum Henry (Trichometasphaeria pedicellatum Nelson) to enhance the fungus’ invasion of corn roots, with a subsequent increase in severity of root rot disease and a decline in productivity. Water stress appeared to influence the response of the corn plant to the root rot disease rather than the disease development.
