Persistence of carbosulfan was studied under laboratory conditions in black, red and alluvial soils following application @ 5 and 10 mg kg−1. Carbosulfan residues progressively declined with time and reached below detectable level (<0.01 mg kg−1) within 75 days in red and alluvial soil and 90 days in black soil. However, more than 95% of carbosulfan degraded within 60 days after incubation irrespective of the soil type and concentration.
