Okra: Out of a total, 36 samples of okra analyzed, 15 were
found to be contaminated with the residues of selected
OP pesticides. The results of residues detected in
vegetable samples collected, from the farm gate are
presented through the Fig 4.2 and Table 4.3. The results
indicated that at raw stage the highest Profenofos residue
was found in egg plant were 1.6 mg/kg (ND- 1.6mg /kg);
whereas the four samples were contained pesticide
residues of Profenofos more than the MRLs and 7(19%)
samples of okra were observed to be contaminated with
the residues of chlorpyrifos, that the one sample was
contained residues of chlorpyrifos exceeded from the
MRLs. Five samples of okra found to be contaminated
with the residues of triazophos. The initial data collected
in the survey showed that the usage of profenofos was
more on the okra crops as compared to that on others.
During the survey it was also observed that, in many
cases, okra was grown near the cotton field and the
farmers used same treatment of insecticide, without
differentiating the two crops.
