A survey of in vitro sensitivity of twelve isolates of the Phytophthora infestans to the fluazinam, fosetyl-Al and propamocarb-hydrochloride was conducted. The isolates were isolated from infeceted potato leaves collected from eight different localities in Serbia during 2005-2007. All P. infestans isolates were sensitive to tested fungicides. The obtained values of resistance factor were in the range from 1.0 to 2.8. The EC50 values of fluazinam were from 0.14 to 0.27 mg/l, fosetyl-Al from 30.2 to 85.8 mg/l, propamocarb-hydrochloride between 12.1 and 31.1 mg/l, respectively.
