Earthworms are soil engineers that alter the soil bio-physical properties to favor plant growth whereas pesticides represent a significant threat to their abundance and soil health. Thus, we investigated the toxic effects of tribenuron-methyl (TBM) and tebuconazole (TEB) on the soil earthworm, Eisenia fetida. The TBM demonstrated low toxicity to E. fetida in the contact filter paper and artificial soil tests, with median lethal concentrations (LC₅₀) of 135.6 μg cm⁻² at 48 h and 511 mg kg⁻¹ on day 14, respectively. Similarly, TEB also showed low toxicity to E. fetida in the artificial …
