title: Impact analysis of IPM programs in Basmati rice by estimation of pesticide residues.
abstract: Samples of Basmati rice grain, soil and water were collected, from IPM and non-IPM field trials conducted at four regions of Haryana, Uttar Pradesh and Uttarakhand in India, for pesticide residue analysis. Out of 45 soil samples collected, only four non-IPM samples indicated the presence of chlorpyrifos and endosulfan in the range of ND (<0.001) to 0.05 mg/kg. Carbendazim used at two locations of Dehradun and Kaithal was found below detectable limit (<0.05 mg/kg) in both IPM and non-IPM trials. Out of total 22 samples of water analyzed, chlorpyriphos was detected in samples from Kaithal and Pant Nagar in the range 0.003-0.006 μL/L, alpha -endosulfan isomer was detected in the range 0.005-0.03 μL/L and the beta-isomer in the range 0.005-0.02 μL/L in sample from Pant Nagar and Kaithal. The residues in all the grain sample of paddy were below detectable limit (<0.001-0.05 mg/kg). The insecticides applied in IPM as well as non-IPM trials were found to be below maximum residue level (MRL).
