Various technologies of sugar beet productions are conducted in our growing region. They are different from locality to locality, from producer to producer, usually disregarding principles of good agricultural practice that include agrotechnical operations, disease control and proper cultivar selection. In extreme agroecological conditions that cause stress in plants, sugar beet is prone to attack of plant pathogenic fungi that cause root rot. Variations in symptoms and diverse types of rot happen as a result of different meteorological and agrotechnological conditions in which sugar beet is grown. Also, they are influenced by the various amount and type of infective material that is deposited and always present in the soil. This paper presents results on type of symptoms, phytopathological isolations and determination of fungi that cause sugar beet root rot from three characteristic growing regions: in Srem (Inđija), Banat (Ečka) and Bačka (Rimski Šančevi) during 2010. In all localities root rot intensity was low (Inđija-0.2%, Ečka-2.89%, Rimski Šančevi-0.5%). In Inđija, wet root rot was prevailing as a symptom and the dominant causer was Macrophomina phaseolina (95.7%), while in Ečka widespread symptom was dry tap root rot caused by Macrophomina phaseolina (in 60.8% cases) and Fusarium spp. (in 41% cases). In Rimski Šančevi, dry tap root rot was completely caused by Fusarium spp.
