Persistence of cyantraniliprole in sandy loam soil and effect of organic manure amendment

The persistence of cyantraniliprole, a new systemic insecticide of the class anthracitic diamide, was studied under the laboratory conditions in sandy loam soil and the soil amended with farmyard manure (0.5%), after spiking at 1, 2 and 4 ?g kg-1 levels in three different soil moisture regimes viz. air dry, field capacity level and also in saturated conditions. Degradation was comparatively faster in saturated than at field capacity and air dry condition. There was an increase in the persistence with increase in the spiking concentration. The persistence of cyantraniliprole was dependent on soil moisture condition, organic matter content and concentration of cyantraniliprole used.
