Abstract

A two season field experiment was conducted to study the magnitude of Benthiocarb residue in transplanted paddy field soil of plough layer (6″), beyond the plough layer (12″) as well as in harvested straw, grain and husk. Transplanted paddy fields were treated once with Benthiocarb (Saturn 50 EC) @1500 g.a.i., 2500 g.a.i. and 3000 g.a.i.ha ^-1. Irrespective of any season, the initial deposits (4 h after spraying) of Benthiocarb in 6″ soil layer were found in varying range of 4.01-4.22 ppm, 5.98-6.56 ppm and 7.47-8.19 ppm at recommended (T ₁), intermediate (T ₂) and double the recommended doses (T ₃) respectively. In paddy field soil Benthiocarb residue dissipated 70% and 90% within 3 and 30 days respectively. Irrespective of any dose and season no residues were detected in 12″ soil layer as well as in straw, grain and husk samples at harvest.
