Secondary metabolite profiles and biological activity of extracts from various isolates fungi Alternaria sonchi depending on the composition of the liquid nutrient medium

Abstract

Phytopathogenic fungus A. sonchi is able to produce metabolites with insecticidal properties. The composition of the culture media affected the metabolite profiles of the extracts. The results of the assessment of biological activity allowed to divide the working isolates with phytotoxic and insecticidal activity.
