THE DISSIPATION OF DIAZENON RESIDUES IN SOME FRUITS an‎d VEGETABLES

The dissipation of diazenon residue from some fruits and vegetables such as rocket, parsley, lettuce, fig, grape and guava was studied. The insecticide residues require 10-13 days to come down to the tolerance limits. The extraction has been done with acetonitrile followed by cleanup using solid phase florisil cartridges. High performance liquid chromatography (HPLC) instrument was used for determination.
