TOPAS Nematode resistant White mustard White mustard
Details
Effective nematode reduction due to long stimulating period
Name addition
Nematode resistant White mustard
- 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
