Nematode resistant Oil radish


Top level of nematode control


  • Best results in resistance tests against Beet Cyst Nematodes - more than 90 % reduction in official tests
  • COLONEL is highly effective and reduces the nematode population under the damage threshold - even a minor presence of nematodes can be reduced effectively
  • Dense foliage for effective weed suppression due to a strong and healthy youth development
  • The characteristic change from the vegetative to the generative development increases the frost susceptability and leads to an even mulch layer
  • Perfectly suitable for sugar-beet/potato crop rotations due to ist inhibiting effect on the Tobacco Rattle Virus (cause of Corky Ring Spot)
  • COLONEL transforms available nutrients into a rich mass of organic matter which is favorable for a stabilized humus balance
  • Excellent suitability for agricultural blends

Cultivation recommendations:

Recommended sowing rate 25 - 30 kg/ha
Sowing depth 2 - 3 cm
Sowing period Mid July until early September - depending on location! Early sowing increases successfully the reduction
Fertilization 40 - 60 kg N/ha
Crop protection Usually there is no plant protection required.
Sowing method In order to gain a fast and even development of the oil radish plants, drilling after careful soil preparation is recommended.
