Field and laboratory experiments were conducted to study the residues and dis-sipation of Fluopyram, a succinate dehydrogenase inhibitor (SDHI) and tebu-conazole, demethylation inhibitor (DMI) used for the control of powdery mil-dew and Anthracnose diseases in grape. Residues of fluopyram dissipated with a half life of 4.04 and 5.18 days, at recommended and double dose, respectively. For tebuconazole, the half life values recorded were 4.75 and 5.42 days, respectively. The residues reached below quantification limit (BQL) on 10th and 15th day, in both the fungicides at recommended and double the recommended dose, respectively, which suggests a Pre-Harvest Interval (PHI) of 7.76 and 9.91 days for fluopyram and tebuconazole, respectively when applied at 75 g a.i./ha and 150 g a.i./ha.
