Nematode resistant White mustard


Effective nematode reduction due to long stimulating period


  • High nematode resistance in the upper range of resistance level 2 - up to 90% reduction
  • Combination of rapid initial development and late flowering ensures a long period of vegetative growth
  • The remaining warmth of the soil can be effectively used for nematode control, at early sowing dates
  • TOPAS is an important part in nematode control management in intensive sugar beet cultivation regions and contributes to the protection of the sugar beet yield
  • As a vital and mass-vigorous variety TOPAS contributes to the weed suppression and increases the humus content of the soil
  • Especially recommended for mulch sowing and water protection areas
