Abstract:
Cercospora leaf spot, caused by the fungus Cercospora beticola Sacc. is the most important disease of sugar beet (Beta
vulgaris L.) worldwide. Cercospora leaf spot is a polycyclic disease that can cause multiple infections during the
vegetation period. Preliminary observations and data regarding sugar beet yield and quality suggestes a differential
behavior of the cultivars to the Cercospora beticola Sacc. fungus infection. The experience highlights the behavior of
the studied sugar beet cultivars to the attack of the Cercospora beticola Sacc. fungus and it was located in the Research
and Agricultural Research and Development Station (SCDA Secuieni), Neamt County. The biological material used is
represented of 36 sugar beet cultivars that are belong to Strube D & S GmbH and their placement was randomized in 4
repetitions. Considering the climatic conditions and applied culture technology, the recorded results regarding the
behavior of the 36 sugar beet cultivars have shown both different levels of resistance and similar to the attack of
Cercospora beticola Sacc. fungus.
