Backgroud  Though it is toxic to humans, dichlorvos is a widely used chemical pesticide and plays an important role in the control of plant pests. The application of a combination of the biocontrol agent  Trichoderma  with dichlorvos may reduce the need for chemical pesticides. Therefore, revealing the specific molecular mechanism of  Trichoderma  tolerance to dichlorvos has become particularly important.    Results  In this study, using transcriptome and metabolome analyses, changes in primary and secondary metabolisms in  Trichoderma asperellum  TJ01 were comprehensively studied in the presence of dichlorvos. A novel C 2 H 2  zinc finger protein gene, zinc finger chimera 1 ( zfc1 ) ,  was discovered to be upregulated, along with a large number of oxidoreductase genes and ABC transporter genes under dichlorvos stress. In addition, gas chromatography-mass spectrometry (GC-TOF-MS), and liquid chromatography-mass spectrometry (LC-QQQ-MS) data revealed the global primary and secondary metabolic changes that occur in  T. asperellum  TJ01 under dichlorvos stress.    Conclusions  The tolerance mechanism of  T. asperellum  TJ01 to dichlorvos was proposed. In addition, the absorption and residue of dichlorvos were analyzed, laying the foundation for elucidation of the mechanism by which  T. asperellum  TJ01 degrades pesticide residues.
