Diseases
Beta vulgaris Fodder Beet Group
A fungal disease caused by the pathogen Cercospora beticola Sacc. that affects the crop's leaf apparatus. The disease leads to the death of older leaves and the depletion of the root crop due to the need for repeated formation of the leaf rosette.
In the reference 24 varieties crop Mangelwurzel, where this is mentioned in the description.
The causal agent is the highly specialized fungus Cercospora beticola Sacc., which belongs to the order Mycosphaerellales. The pathogen is characterized by high genetic plasticity; however, a clear classification into specific pathotypes in relation to fodder beet is currently unavailable.
A characteristic sign of the infection is the presence of small, round spots 2–5 mm in diameter, light brown or grayish-yellow in color, bordered by a reddish-purple ring. Under conditions of high humidity, a characteristic velvety, grayish-white coating of conidial sporulation forms on the spots on both sides of the leaf.
Severe development of Cercospora leaf spot triggers premature curling, drying, and death of the leaves. The plant is forced to utilize nutrients stored in the root crop for the regeneration of leaf mass, which leads to a significant decrease in productivity.
Specific resistance genes to this disease in fodder beet have not been described in detail. Breeding work is being conducted with quantitative resistance traits and the search for promising breeding lines, as the genetic background of susceptibility to the pathogen is complex.
