ABSTRACT: A field trial was conducted under West Bengal condition during July 2009 to October 2009 to evaluate the harvest residue of Tebuconazole (25.9% EC) in paddy at two application rates (750 and 1500 mL ha–1). Another field trial was conducted during August 2009 to December 2009 to evaluate the harvest residue of the same molecule in groundnut. The quantitative analysis of the fungicide residue was performed using Liquid Chromatography-Mass Spectrometry (LC-MS/M S). The average recovery was found in between 86.33 to 91.87% for different substrates of groundnut. In case of paddy the average recovery was ranges in between 86.40 to 90.86% for different substrates. In all the cases, it was found that the fungicide residues were below the detection limit of the instrument (
