The new generation Cercospora varieties
The new generation Cercospora varieties:
We change the rules.
Get the best of both dimensions: Protection + Performance.
The new generation Cercospora varieties follows a new rule: A high level of tolerance AND a high performance under both high and low Cercospora pressure.
This new tolerance has been identified in a large breeding population which KWS mainly derived from a broad range of wild beet material from Beta vulgaris ssp. maritima. Developed by classic breeding methods.
Field trial in The Netherlands (2020): New variety with improved Cercospora tolerance compared to current Cercospora-tolerant variety, both under disease infestation.
The new and powerful Cercospora variety generation will offer a novel dimension in disease suppression and yield performance:
Superior Cercospora Leaf Spot management.
- Maintain strongest Cercospora protection throughout the growing season even under highest disease pressure. And having a potential for fungicide savings.
- Keeps the leaf area of your crop healthy and active for full sugar production.
- A superior performance to current Cercospora tolerant varieties under high Cercospora pressure.
- No significant yield gap compared to products w/o Cercospora tolerance in case of absence of Cercospora infestation.
Sugarbeet is in a tough environment
Changing disease pressure
Cercospora puts sugarbeet in a tough environment:
- Roughly two third of the global sugarbeet acreage are characterized by a risk of moderate to high Cercospora pressure (i.e. about 3 mha). Observations show that the disease conquers new territory by spreading from the South to the North in the long term.
- Cercospora Leaf Spot is by far the most destructive leaf disease of sugarbeet - reducing the crop yield by up to 50%* in many places.
- Furthermore, Cercospora leads to inferior processing quality resulting in a reduced productivity and competitiveness of the sugarbeet industry.
Efficacy of fungicides
In future, controlling Cercospora with plant protection products will become more difficult.
- Fungicide resistances spread widely and thus reduce the efficacy of plant protection products.
- A broad use of active substances for the prevention of resistances is no longer possible as their number is being further limited.
- Integrated pest management is becoming increasingly important - farmers are forced to limit their fungicide use as much as possible.
