Electrochemical characterization of salicylic acid and its influence on the phytopathogenic fungus Ophiostoma novo-ulmi

Numerous ancient civilizations knew and used salicylic acid, which is obtained from the bark and leaves of the species Salix sp., but it was not until 1897 that Felix Hoffmann succeeded in synthesizing salicylic acid in a pharmaceutical laboratory. Salicylic acid is a simple phenolic compound that a large number of prokaryotic and eukaryotic organisms synthesize. In a 1979 study, salicylic acid was found to have a function in plant defense against various pathogens [1]. In the territory of the Republic of Croatia, the presence of the phytopathogenic fungus Ophiostoma novo-ulmi was detected, which caused great damage in forest areas and caused the desiccation of elms [2]. In this study, voltammetric measurements will be used to investigate the oxidation of salicylic acid, to determine the effect of scan rate and salicylic acid concentration on the oxidation peak potential and oxidation peak current, and to provide insight into the oxidation mechanism of salicylic acid [3]. By applying different concentrations of alcoholic and aqueous solutions of salicylic acid to genetically different isolates of O. novo-ulmi, the effects of salicylic acid on the growth rate of the fungus and differences in the effects of individual concentrations on the isolates will be determined [4].
