Criconemoides species.
Ring Nematodes


  • Damage to Corn.   Ring nematodes associated with corn usually occur with mixed populations of other species, and are considered responsible for reduction in yield.
  • Biology.   Criconematinae are markedly annulate stubby nematodes, ranging from 0.2 - 1.0 mm in length. 
  • Ecology.   Large populations around corn usually occur only in highly sandy soil.
  • Symptoms
  • Damage to other crops.   Peanuts are also a host of ring nematode.
  • Control.   Rotation with cotton and soybeans has been found to be effective
