The persistence of flupyradifurone, a systemic insecticide of the new class butenolide, is reported under laboratory conditions in a sandy loam soil and the soil amended with 0.5 per cent farmyard manure (FYM), after fortification at 1, 2 and 4 mg kg−1 levels at three different soil moisture regimes viz. air dry, field capacity and saturated soil. Degradation was comparatively faster in saturated than the field capacity and air dry condition. There was an increase in persistence with an increase in concentration. The persistence was dependent on soil moisture condition, organic matter content and concentration of flupyradifurone in the treatment. None of the major metabolites of flupyradifurone was detected.
