Nine hydronopol quaternary ammonium salts(hydronopol dimethyl alkyl ammonium halide), which were hydronopol dimethyl ethyl ammonium bromide(2a), hydronopol dimethyl n-propyl ammonium bromide(2b), hydronopol dimethyl n-butyl ammonium bromide(2c), hydronopol dimethyl n-pentyl ammonium bromide(2d), hydronopol dimethyl benzyl ammonium bromide(2e), hydronopol dimethyl benzyl ammonium chloride(2f), hydronopol dimethyl ethyl ammonium iodide(2g), hydronopol dimethyl n-propyl ammonium iodide(2h), and hydronopol dimethyl n-butyl ammonium iodide(2i), were synthesized by the reaction of hydronopol dimethyl amine and 9 halogenated hydrocarbons, respectively. The identification and structural analysis were carried out by using FT-IR, MS and NMR methods, and the inhibition effects of the nine compounds on eight plant pathogens were tested by the method of mycelium growth rate method. The results showed that under the concentration of 500 mg/L, 9 compounds had certain inhibitory effects on the 8 plant pathogenic fungi, among which the bacteriostatic performance of 2d were the best, the bacteriostatic rates against Fusarium proliferatum, Alternaria kikuchiana, Sclerotinia sclerotiorum, Ceratosphaeria phyllostachydis, and Sphaeropsis sapinea reached 100%, and 2b, 2c and 2f also had excellent results, the bacteriostatic rate reached 100%.

Key words: hydronopol, quaternary ammonium salt, synthesis, structural analysis, bacteriostatic activity
