**5. Applicability of the developed method**

#### **5.1 Sampling**

Grape samples were collected from farmers' fields in Vijayapura district in Karnataka. These areas are very popular for the production of grapes, and we see an excessive use of pesticides. The developed analytical method was used for the determination of residues of pesticides in grape samples and that were analyzed in triplicate. The results confirmed that the grape samples contained pesticide residues well above the prescribed level, viz. carbofuran, fenvalerate, triazophos, and endrin (**Table 2**). Grapes which were analyzed in the present study mainly contributed to the major dietary intakes of the citizens in India.
