The main objective of this study was to understand the residue and persistence behavior of Penconazole fungicide in grape fruit samples. The residues were analyzed by GC. The average initial deposit of in grape fruit was observed to be 1.04 mg kg-1 at single application rate. The recoveries of Penconazole on grape fruit were observed from 91.04% to 92.13% at fortification levels of 0.1, 0.5 and 1.0 mg kg-1. The reported limit of quantification (LOQ) was found to be 0.02 mg kg-1. The dissipation experiments showed the half-lives (T1/2) of Penconazole were around 1.56 days. According to the maximum residue limit (MRL) the pre-harvest interval (PHI) of Penconazole on grape was 14 days after the treatment.
