Bacterial burning is a widespread disease in soybeans, which occurs most frequently under cold and wet climate. The objective of this research was to estimate the degree of attack of bacterial burn in oybeans. The goal was to have the necessary information in making decisions applying for phytosanitary treatments. Twenty-five varieties were tested: Columna, Condor, Daciana, Diamant, Dukatt, Eugen, Felix Novisad, Felix PR, Fortezza, Galina, Julija, Merkur, Onix, Perla, PR 20, Procera 12-2, Rubin, Sultana, Sponsor, Tea, Triumf Fundulea, Triumf Novisad, Venera, Victoria and Zora, and observations were made under natural contamination on the 13th of July and August 28, 2013. The research was conducted in the experimental fields without irrigation, in I. C. Bratianu city, county of Tulcea. From this paper it can be concluded that one of the main limiting factors in soybean crop is found in a very large extent of the phytosanitary nature, like the attack of the bacteria Pseudomonas savastanoi pv. glycinea. The degree of infection varied from one variety to another. The study was developed during the proces of doctoral studies.
