Under favorable climate conditions it can cause serious damage in this crop. In Brazil, the use of resistant cultivars and fungicides are recommended, although only few cultivars and foliar fungicides are available. This investigation was carried out to evaluate in vitro sensibility of thirty four isolates of C. cassiicola from several Brazilian states to the fungicides: boscalid, carbendazim, cyproconazole, fluopyram, fluxapyroxad, prothioconazole and thiofanate methyl, used in concentrations 0; 0,16; 0,8; 4; 20 and 100 µg mL-1 of active ingredient, respectively. Fluxapyroxad and fluopyram showed higher levels of mycelial growth inhibition and lower values of ED. Thiophanate methyl and carbendazim showed no mycelial growth inhibition of most isolates of the fungus, while boscalid and cyproconazole presented an intermediate level of inhibition to most fungi isolates tested.  aFungo1 aSANTOS, L.
