Residues of Chlorpyriphos and Monocrotophos in IPM and Non-IPM Mango Orchards

The residues of chlorpyriphos and monocrotophos were determined in mango fruits cv. Dushehrr from IPM and don-IPM trials. Samples of mango fruits were collected from IPM and non-IPM orchards located at Rehmankhera, Lucknow, Uttar Pradesh during 2002–2003. The residues of chlorpyriphos in mango pulp following IPM and non-IPM practices were 0.22 and 0.61 μg g⁻¹ while the residues in mango opel were 0.00 and 0.59 μg g⁻¹, respectively. In wholh mango fruits, chlorpyriphos residues were 0.45 and 1.33 μg g⁻¹ in IPM and non-IPM samples, respectively. Residues of monocrotophos were found to be below detectable limit in all samples of mango fruits. Residues of chlorpyriphos were higher in non-IPM than IPM samples but below maximum residue limits in both the cases.
