The investigations were carried out at Dobrudzha Agricultural Institute – General Toshevo during 2007 – 2008. The efficiency of the following fungicides was tested against common bean rust in artificial infection background: Bravo 500, Quadris 25CK, Artea 33OEK, Falcon 460EK, Falcon sussecsor. Variety Helis, susceptible to the pathogen, was sown in trial plots of 8 m2 each in three replicates. Six treatments were performed at 7-day intervals. Artea 330EK and Falcon sussecsor had the highest efficiency during the two years of investigation (from 100 to 99.9 %) followed by Quadris 25CK and Falcon 450EK. The treatment of the crop with Quadris 25CK and Falkon 460EK lead to statistically significant yield increase. Fungicide Artea 330EK caused phytotoxicity on variety Helis.
