Abstract

The growth response of 25 Trichoderma strains to 26 alkanols and 7 other organic solvents was examined in vitro. The sensitivity of strains considerably varied depending on their taxonomic position, thus the strains of Longibrachiatum section proved to be more tolerant than those of Pachybasium and Trichoderma sections.

Significant relationship was revealed between structure of C~1~–C~24~ alkanols and their growth inhibitory effect to Trichodermas, both efficacy and selectivity of C~1~–C~3~ and C~14~–C~24~ alkanols failed off the C~9~–C~11~ alkanols. The non‐alkanol solvents tested were non‐toxic.

The C~8~‐C~11~ alkanols used in agricultural practices exhibited noticeable toxicity to all Trichoderma strains, therefore pesticidal preparations containing these alkanols cannot be used simultaneously with Trichoderma based biopreparations.
