Some sugar beet cultivars behavior to the attack of Cercospora Beticola Sacc. fungus under climatic conditions from Neamţ county, Romania

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.
