Study of the fungicidal properties of fulvic acids

Abstract

Today, agriculture is developing in the direction of reducing the use of chemically synthesized plant protection products, as they can accumulate in the soil and crops and have a negative impact on the environment and human health. In this regard, it is promising to use organic preparations of natural origin as pesticides, as well as their chemically modified forms. The article presents the results of the study of the fungicidal action of natural fulvic acids isolated from peat by standard methods, as well as organic preparations obtained by chemical modification of the original fulvic acid sulfanes. Fungicidal activity was tested in vitro on fungi-phytopathogens from six different taxonomic groups. The study proves the effectiveness of the use of modified fulvic acids with selective fungicidal properties, as well as the need for further study of the biological activity of the obtained modifiers.
