Vk. Madan et al., Dissipation of lindane and fenvalerate residues in chickpea (Cicer arietinum L.) under Indian climatic conditions, ECOTOX ENV, 46(2), 2000, pp. 163-166
Dissipation behavior of lindane 20 EC (400 and 800 g a.i./ha) and fenvalera
te 0.4% dust (75 and 150 g a.i./ha) applied on chickpea (var. H 208) for co
ntrolling pod borer under field conditions during rabi 1994-1995 at pod ini
tiation stage was studied. Grains from lower dose of lindane at harvest con
tained residues below maximum residue limit value (0.25 mu g g(-1)), wherea
s 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 fen
valerate is suggested from point of hazards due to residues, when applied a
t recommended dose. The residues calculated from consumption of chickpea (6
0 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. (C) 2000 Academic Press.
