Four inorganic salts namely, ammonium bicarbonate (AB), potassium bicarbonate (PB), sodium bicarbonate (SB) and Calcium chloride (CC) were screened for their antifungal activity against spore germination as well as mycelial growth of three plant pathogenic fungi namely Fusarium oxysporum, Alternaria alternata and Botrytis cinerea causal agents of potato dry rot, tomato leaf spot and grape gray mold respectively under labaratory condition. Poisoned food technique and spore germination assay were used for conducting these experiments. Among tested salts, potassium bicarbonate performed highest antifungal activity against all three phytopathogenic fungi followed by sodium bicarbonate. Significant differences were also observed between AB, CC, PB and SB in inhibiting spore germination, as well as mycelial growth of three tested fungi when their concentrations (100 & 200 mM) were considered (p=0.01). The best inhibitory effect in both experiments were achieved by PB (200 mM) followed by SB (200 mM), PB (100 mM) and SB (100 mM), while the least inhibitory effect on all tested fungi was observed by CC (100 mM).
