Dissipation of Lindane and Fenvalerate Residues in Chickpea (Cicer arietinum L.) under Indian Climatic Conditions

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 μg 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.
