Comparative study of pesticide residue pattern in vegetables grown under IPM and non-IPM practices

Debi Sharma, P N Krishnamoorthy, A krishnamoorthy


Pesticide residue persistence pattern in three vegetable crops viz., tomato, cabbage and cauliflower cultivated following previously developed pesticide residue free IPM packages was compared with that, in these crops, cultivated under conventional or non-IPM conditions. It was seen that the vegetables grown as per IPM practices were safer to consume at harvest as compared to those grown as per the conventional cultivation practices with chemical control as the sole means of plant protection. In vegetables grown by adopting IPM practices, pesticide residues, if present, were mostly present in trace level (<0.01 ppm) except somewhat higher levels of pesticides methomyl and monocrotophos in cabbage.
