[Phytotoxic activity of chernozem saprophytic micromycetes: specificity, sorption and stability of phytotoxins in soil].

Micromycetes of the complex of typical chernozem saprotrophic fungi released phytotoxic metabolites into medium. The metabolites displayed their phytotoxic activities directly in soil. Evaluation of the toxicities, range of biological effects activities, and stabilities of phytotoxins in soil and the rates of their biodegradation allowed the species that can serve as indicators of chernozem microbial toxicosis to be selected, namely, Aspergillus clavatus, Fusarium solani, Talaromyces flavus, Penicillium rubrum, and P. funiculosum.
