Residues of aldicarb, applied as broadcast and in furrow, at 1.25, 1.0 and 1.5 kg a.i./ha, persisted for about 60, 120 and 120 days, respectively in sandy loam soil cropped with cowpea, pea and okra. Initial degradation of aldicarb residues was rapid upto 15 days and slow subsequently in all the three cropping seasons. The differential persistence of aldicarb residues are attributed more to the method of application than moisture and temperature condition.
