Manage your Beet Cyst Nematode population
Beet cyst nematodes can severely affect your yields and can cause losses between 30% and 60% if non-tolerant beet varieties are grown in infested conditions.
If you are aware of BCN in your fields, the target should be to manage the BCN population to prevent any further increase. One tool to keep your BCN populations low are long rotations (> 5 years) without suitable host crops, which also include weeds e.g. fat hen (Chenopodium album), orache (Atriplex patula) or shepard’s-purse (Capsella bursa-pastoris). The choice of a BCN-tolerant sugar beet variety will further assist to keep the population at a low level. BCN infestation can be unnoticed if typical symptoms like wilted, yellow patches, bearded roots with cysts are not seen in the field, but even in these situations you may already be losing 10% of yield to BCN. Soil samples will help to clarify the degree of infestation in your field.
The BCN management tool will demonstrate the potential risk of your chosen crop rotation and the impact this could have on the BCN population. If the barometer shows red, it is strongly recommended to reconsider the planned rotation.
To start the tool just drag and drop the crops of your typical rotation in the boxes. The tool is pre-set to start with sugar beet and a low-medium BCN population.
