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-1, fosetyl-Al from 30.2 to 85.8 mg l-1, propamocarb-hydrochloride between
12.1 and 31.1 mg l-1, respectively. Ispitivana je osetljivost 12 izolata Phytophthora infestans na fluazinam, fosetil-Al i propamokarb-
hidrohlorid u in vitro uslovima. Izolati su dobijeni iz zaraženih listova krompira sakupljenih
tokom 2005-2007 godine sa osam različitih lokaliteta iz Srbije. Svi ispitivani izolati
su bili osetljivi na testirane fungicide. Dobijene vrednosti faktora rezistentnosti bile su u intervalu
od 1.0 do 2.8. Vrednosti EC50 za fluazinam su bile od 0.14 do 0.27 mg l-1, fosetil-Al od
30.2 do 85.8 mg l-1 i propamokarb-hidrohlorid od 12.1 do 31.1 mg l-1.
