STUDY ON PESTICIDE RESIDUES OF SELECTED VEGETABLES<br />

monocrotophos and mancozeb) on vegetables grown<br />

in India were observed by Dethe et al. (1995).<br />

Detectable levels <strong>of</strong> residues <strong>of</strong> endosulfan,<br />

cypermethrin, dimethoate, monocrotophos and<br />

mancozeb were observed in 33.3% samples <strong>of</strong><br />

tomatoes (endosulfan, dimethoate and<br />

monocrotophos), 73.3% samples <strong>of</strong> brinjal<br />

(endosulfan, cypermethrin , fenvalerate, quinalphos,<br />

dimethoate and monocrotophos), 14.3% samples <strong>of</strong><br />

okra (endosulfan), 88.9% samples <strong>of</strong> cabbage<br />

( endosulfan, fenvalerate and dimethoate) and 100%<br />

<strong>of</strong> cauliflower ( endosulfan, fenvalerate, dimethoate,<br />

cypermethrin, and monocrotophos). However, the<br />

levels <strong>of</strong> pesticide residues were below the prescribed<br />

MRLs.<br />

Moreover, pesticide residues in all the selected<br />

vegetables were below detectable level (BDL) in both<br />

whole and processed vegetables which reflects that<br />

the pesticides used were highly volatile and required<br />

holding period was taken to harvest the product.<br />
