Residue Determination Of Dimethoate In Grapes And Tomatoes Using RP-HPLC
Residues of dimethoate were analyzed in different grapes (paneer, green, seedless violet) and tomatoes (nattu and Bangalore). Analyses were performed by HPLC using a reversed-phase column (RP-18). Extractions from grapes and tomatoes were carried out with benzene. The residues found in grapes were lower than the admissible limits mentioned by FDA, whereas in case of tomatoes, the residues were found to exceed the limits prescribed by FDA to a slight extent.
