title: Determination of pesticide residue in soil, water and grain from IPM and non-IPM field trials of rice.
abstract: Soil, water and rice grain samples from field trials conducted under the IPM and non-IPM modules in Kaithal (Haryana) region were analyzed for pendimethalin, atrazine, lindane and chlorpyriphos, and in Dehradun (Uttarakhand) region, samples were analyzed for carbendazim only. The pesticide residues were found below the detectable limit in the soil and water samples of the Kaithal region. From Dehradun region the residues of carbendazim in rice grains were detected at 0.001 mg/kg level, and in soil they were in the range of 0.03-0.001 mg/kg. The insecticides applied in IPM as well as non-IPM trials in both regions were observed to be below the prescribed maximum residue level.
