Demo Columbia root knot nematode

  • You are growing potatoes in a 1:4 rotation.
  • You had a field sampled with the Combi method in August, immediately after a winter wheat crop.
    Result Meloidogyne chitwoodi (Columbia root knot nematode) 50 larvae/100 cc on one of the parts of the sampled field.
  • You wish to restrict expansion of the infestation as much as possible.
  • You wish to grow ware potatoes in 2011 and 2015.
     
    Crops Green manure crops
    Potatoes Rye
