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 />
