Nanopesticides exhibit different residue patterns in crops after application compared to conventional formulations, thus affecting human dietary exposure. Residue, dissipation, and dietary exposure to tebuconazole nanoformulations (nanoemulsion and nano-capsules) and conventional formulations (suspension concentrate and micro-capsules) on wheat were investigated and compared. Nano-capsules (1950 μg/kg) and micro-capsules (1771 μg/kg) had significantly lower initial deposition on wheat-leaf than suspension concentrate (2666 μg/kg). No significant differences were observed in initial deposition on wheat-stem and wheat-grain between nano and conventional formulations. The degradation half-lives of suspension concentrate, nanoemulsion, nano-capsules, and micro-capsules were 1.5-11.4 d, 7.6-25.7 d, 4.1-12.4 d, and 7.5-22.4 d, respectively. Nanoemulsion, with the lowest surface tension, was highly stable and persistent, resulting in the highest final residues on wheat-leaf (695 μg/kg). Risk quotients for all formulations were about 28 %, indicating acceptable dietary risks. These findings offer valuable insights into the application of nanopesticides and contribute to mitigating the associated health risks.
