AB  - A study was undertaken to evaluate the decline of the residues of pyridalyl in 
      tomatoes grown in two different cultivation systems: open field (conventional 
      cultivation) and net house (pot experiment). Field experiment was conducted with 
      commercial (10 EC) and nanoformulation of pyridalyl on tomato crop. Tomato plants 
      were subjected to pesticide spray, when fruits were close to ripeness. Fruit 
      samples were taken periodically and cleaned up using QuEChERS methodology, and 
      the residue of pyridalyl was analyzed by ultrahigh-performance liquid 
      chromatography (UHPLC). It dissipated in tomato fruit following the first-order 
      kinetics. In field, average initial deposit of pyridalyl in tomato was observed 
      to be 0.222 and 0.371 mug g(-1) at recommended and double the recommended 
      application rate, respectively, using nanoformulation while it was 0.223 and 
      0.393 mug g(-1) on using commercial formulation, respectively. The half-life 
      (t1/2) value of nanopyridalyl in tomato fruit was 2.8 and 3.2 days while for 
      commercial formulation, it was 2.5 and 2.6 days for recommended and double the 
      recommended dose, respectively. In India, maximum residue limit (MRL) on tomato 
      has not been fixed for pyridalyl but its residues were always below European MRLs 
      (5 mug g(-1)) on tomato at both application rates. The results of terminal residue 
      showed that pyridalyl residues were below the available MRL. Low residues in 
      tomatoes suggested that this pesticide is safe to use under the recommended 
      dosage. No statistical differences were observed between the cultivation systems 
      in relation to the residue levels of pyridalyl.
