dc.description.abstractThe uptake and metabolism of imidacloprid in sugarcane leaves and soil were studied following application of imidacloprid @ 20 and 80 g a.i. ha-1. Samples of sugarcane leaves and soil were collected at various time intervals and analyzed by using High Performance Liquid Chromatograph (HPLC) and confirmed by Liquid Chromatograph –Mass Spectrometry (LCMS). Total residues of imidacloprid and its metabolites were found to be 4.97 and 12.99 mg kg-1 in leaves collected 7 days after the application of imidacloprid @ 20 and 80 g a.i. ha-1 respectively. These residues declined to below the detectable limit at 90 days after the application at both the dosages. The samples of sugarcane juice and trash did not reveal the presence of imidacloprid residues at harvest. In soil samples total residues of imidacloprid were found to be 4.29 and 7.81 mg kg-1 collected 7 days after the application @ 20 and 80 g a.i. ha-1 respectively. These residues could not be detected at 90 days after the application at both the dosages. In laboratory experiment, residues of imidacloprid in sandy loam, loamy sand and clay loam after 7 day of its application @ 100 mg kg-1 were found to be 69.74, 72.66 and 77.20 mg kg-1, respectively. The persistence of imidacloprid was almost similar in all type of soils. In sterilized soil, Bacillus alkaninitricus was found to be more efficient than B. aerophilus and their consortium while, in unsterilized soil, bacterial consortium proved to be more efficient in imidacloprid degradation.en_US
