โฆ Synopsis
Residual fate and behaviour of the herbicide oxadiazon in Kalyani soil, paddy straw and grain were studied under subtropical conditions, in West Bengal following application @ 1 kg and 2 kg ha ร1 . Dissipation of oxadiazon in soil followed ยฎrst-order kinetics and DT 50 values ranged from 44 to 45 days. Residues at harvest in paddy grains and straw were also studied. Degradation of oxadiazon after 60 days of incubation at 28(AE 1) ยฐC in alluvial soil at water holding capacity yielded 10 metabolites of which four were characterised by spectroscopy.
