Implication

Experimental study demonstrates fungal pathogen inhibition and enhanced seedling growth by Trichoderma koningiopsis volatiles, highlighting airborne biocontrol potential.

Key Points

To evaluate the indirect biological control efficacy and plant growth promotion capabilities of volatile organic compounds produced by Trichoderma koningiopsis T-51.
Assessed in vitro mycelial growth inhibition, conidial germination, and germ tube elongation of Botrytis cinerea and Fusarium oxysporum exposed to T-51 volatile organic compounds (VOCs).
Evaluated biocontrol of Botrytis fruit rot on tomatoes and measured growth impacts on Arabidopsis thaliana seedlings.
Profiled the chemical composition of T-51 VOC emissions using analytical detection methods.
T-51 VOCs inhibited mycelial growth by 73.78% in B. cinerea and 43.68% in F. oxysporum, while delaying conidial germination and suppressing germ tube elongation in both pathogens.
Treatment with T-51 VOCs significantly decreased the final conidial germination rate of B. cinerea and reduced Botrytis fruit rot in tomatoes compared to controls.
Exposure to T-51 VOCs, comprising 24 identified alkenes, alkanes, and esters, significantly increased the size and weight of Arabidopsis thaliana seedlings.
