COLONEL

Nematode resistant oil radish

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
