Abstract
The aim of this study was to investigate the dissipation kinetics of ethofumesate belonging to the benzofuranyl alkanesulfonate group in sugar beet plant and field soil as influenced by methods and quantity of application under Indian tropical condition. The quantification of ethofumesate was carried out in ion trap model GC-MS. The method was validated by evaluating the analytical curve, linearity, limits of detection and quantification, precision (repeatability) and accuracy (recovery), after the optimization of extraction parameters for the determination. The method provided limits of quantification of 0.05 mg kg-1 for different matrices with the method detection limit of 0.01 mg kg-1 for all matrices. The developed method was applied to study the dissipation kinetics and persistence of ethofumesate in sugar beet crop and soil from the field experimentation which received two different doses along with control. It was found that the ethofumesate dissipation followed first order kinetics with a half-life of 7.5 and 5.9 days under single application and 5.3 and 2.6 days under split application in soil and plant respectively. Application of ethofumesate at 0.99 kg a.i. ha-1 degraded before the harvest which limited the risk for agricultural environment contamination.
