In the present work, persistence and degradation of cyantraniliprole, a leading anthranilic diamide
pesticide against sucking insect pests, in inceptisol soil has been studied. Effect of various factors
like light source (UV-light, sunlight and dark), temperature (5, 25 and 37 C), moisture regime (dry,
field capacity and submerged) and carbon dioxide level (415 and 625 mL L1
) on dissipation was
also evaluated. Formation of IN-J9Z38, a major metabolite of cyantraniliprole, was monitored in
different treatments. Samples were processed as per QuEChERS method and analysis was done by
HPLC-PDA. Matrix matched calibration curve, prepared in the range 0.001–10 mg L–1
, indicated
very good linearity (R2 > 0.99) and sensitivity (instrument limit of detection 0.001 mg L–1
).
Cyantraniliprole residues dissipated with time and 47.7%–98.8% dissipation was recorded on 90th
day in different treatments. Minimum half-life of cyantraniliprole, i.e. 8.7 days was recorded at elevated CO2 level (625 ± 5 mL L1
) while its maximum half-life of 86.6 days was recorded at 5 C.
Metabolite IN-J9Z38 started forming from zero-day and reached the maximum on 15th to 60th
day. Microbial biomass carbon, as an index of microbial activity of soil, correlated well with the
degradation of cyantraniliprole.
