Dissipation behavior of lindane 20 EC (400 and 800 g a.i./ha) and fenvalerate 0.4% dust (75 and 150 g a.i./ha) applied on chickpea (var. H 208) for controlling pod borer under field conditions during rabi 1994-1995 at pod initiation stage was studied. Grains from lower dose of lindane at harvest contained residues below maximum residue limit value (0.25 microg g(-1)), whereas no measurable amount of fenvalerate residues were found in grains of both doses at harvest. A waiting period of 7 days for lindane and 1 day for fenvalerate is suggested from point of hazards due to residues, when applied at recommended dose. The residues calculated from consumption of chickpea (60 g/person/day) is much below the maximum permissible intake of lindane and fenvalerate; hence the recommended doses can be considered safe from point of view of hazards to humans.
