Persistence of imidacloprid was studied under laboratory conditions in four types of soil viz.sandy loam, clay, red and black soils following treatment at 1.0, 2.0 and 4.0 μg/g fortification levels. The imidacloprid residue in the soil samples were measured by validated analytical method. The dissipation of imidacloprid was found to be faster in black soil followed by sandy loam, clay and red soil with half life value of 50.10, 42.74 and 45.69 days, respectively.
