Abstract: Seven N-hydronopol pyridine quaternary ammonium salts,which named which named N-hydronopyl pyridine ammonium bromide(2a), N-hydronopyl pyridine ammonium iodide(2b), N-hydronopyl pyridine ammonium chloride(2c), N-hydronopyl-γ-dimethylamino pyridine ammonium bromide(2d), N-hydronopyl-γ-dimethylamino pyridine ammonium iodide(2e), N-hydronopyl-α-methyl pyridine ammonium iodide(2f), N-hydronopyl-γ-methyl pyridine ammonium bromide(2g), were prepared from the quaternization reaction of pyridine or pyridine homologues(α-methylpyridine, 4-dimethylaminopyridine, 4-methylpyridine) with hydronopol halides chloride, hydronopol halides bromide, hydronopol halides iodide, respectively. The identification and structural analysis were done by using MS, NMR(1H NMR,13C NMR) and FT-IR methods. And the antifungal activities of all compounds against Botryosphaeria dothidea, Phoma citricarpa, Colletotrichum glecosporioides, Pestalotiopsis actinidia and Phomopsis mauritiana were studied by using the mycelial growth rate method. The antifugal activity test showed that at the mass concentration of 500 mg/L, the compounds had certain antifungal activity against five tested phytopathogens. Among all compounds, the inhibition rates of 2d and 2e against P.citricarpa, P. actinidia were 100% and higher than the inhibitory effect of carbendazim. And the inhibition rate of 2d against B. dothidea were 100% and equal to the inhibitory effect of carbendazim.
