Abstract
Dissipation pattern and risk assessment of tebuconazole in grapes was studied following two application rates (250 and 500 mL ha−1) under tropical humid climatic condition of West Bengal during 2009–2010. Residues of tebuconazole were confirmed by liquid chromatography–mass spectrometry. The average recoveries were found 87.53 % and 89.67 % for grapes and cropped soil respectively. Following the first order kinetics the fungicide dissipates in grapes with a half-life (T1/2) value ranges between 2.62 and 2.86 days irrespective of seasons and doses. No residues of tebuconazole were detected in harvest grapes and soil samples which refers that, tebuconazole does not possess any background contamination property in grapes. So it may be concluded from the study that tebuconazole does not possess any toxicological property when applied at the recommended dose.
