“…All the values were in the acceptable range for detection and trace residue analysis which is usually between 70 and 120%, RSD 20% maximum and LOQ according to MRL (maximum residue limit) of the compound [22]. Scientists had reported earlier, single method of analysis for both herbicides and the detection limit oryzalin residues from soil/water by analytical methods ranged from 0.001 to 0.05 mg g À1 and recovery ranged from 87 to 91% for soil and 70-94.7% for water while, for ethofumesate the detection limit were 0.0001-0.0005 mg g À1 by different chromatographic methods, and percent recovery ranged from 78 to 94% for soil and 90-96% for water, respectively [11,12,14,15,16].…”

“…Pesticide monitoring in soil and water is essential to know the status of pesticide in environment. Individually, an oryzalin and ethofumesate residue in different matrixes has been reported using [9][10][11][12][13][14][15][16][17][18][19]. As per literature search no study had been reported on simultaneous determination of these pesticides residues from soil and water.…”

A sensitive and reliable method for simultaneous determination of oryzalin and ethofumesate residues in pantnagar soil and water was validated. The compounds were extracted by LLE with dichloromethane from water, and acetone:methanol mixture from soil followed by SPE cleanup. Detection and quantification was done by RP-HPLC using mobile phase methanol:water (70:30, v/v) at 280 nm. The developed method showed satisfactory validation results with linearity (0.99), relative standard deviations (1.55 and 1.73%), and limit of quantification (0.002 μg g−1 and 0.005 μg g−1) for ethofumesate and oryzalin, respectively. Recoveries ranged for oryzalin and ethofumesate from 79.80–90.52, 75.58–86.04% (soil) and 83.50–95.92, 82.28–94.60% (water), respectively. The method could be used for routine high-throughput detection and determination of these compounds.

“…Under low moisture aerobic conditions in sandy loam soil, the half-life was 253 days whereas, under moist conditions in silt loam and sandy loam soils, the half-life was 83 and 122 days, respectively [9]. Scanty information [10] is available on the persistence study of ethofumesate in soils and crops under tropical conditions, although some work on persistence from other regions is reported [11][12][13][14][15][16].…”

Indiscriminate use of pesticides and growing awareness of environmental and health problems had led to monitoring their residues in soil and crops. Ethofumesate is one of the widely used herbicides for controlling weeds in sugar beet. Dissipation kinetics and terminal residues of ethofumesate were investigated in two diverse soils under subtropical field conditions. Ethofumesate dissipated slowly after application and follows biphasic first-order kinetics in soils. The average half-life for initial and later phases in sandy loam soil, respectively, was 14.54 and 20.42 and 51.83 and 65.21 days, while for silty clay loam, it was 10.09 and 13.00 and 71.42 and 73.10 days, respectively. Recoveries in soil, leaves, and beetroot ranged from 78.15 to 88.05, 77.01 to 88.58, and 76.25 to 84.50%, respectively. The quantitation limit for soil, roots, and leaves was 0.002 μg g−1. At harvest, no residues were detected in soils, leaves, and sugar beetroots. Residues were below the maximum residue limits in sugar beetroots and leaves as set by EU (0.2 ppm). Ethofumesate is safe from weed control and environmental aspects as it does not persist for a long duration in soils and does not appear to pose any adverse effect on human/animal health under subtropical field conditions.
