Degradation dynamics, correlations, and residues of carfentrazone-ethyl, fenoxaprop-p-ethyl, and pinoxaden under the continuous application in the wheat field

A new multiresidue thin layer chromatography–ultraviolet detection method for the rapid determination of six herbicides residue applied as ready mix formulation for rice

“…LOD of 0.001 mg/kg for atrazine and metribuzin in soil and crop by HPLC is reported by Sondhia and Yaduraju [45]. The LOD of the reported TLC method was found to be 0.1 mg/kg for penoxsulam and pretilachlor herbicides and 0.01 mg/kg for cyhalofop-butyl, ethoxysulfuron, traifamone, and pyrazosulfuron-ethyl herbicides (Table 3) which is equivalent or at par to the LODs of sophisticated instrument methods (GC/MS, LC/MS/MS, and HPLC) reported by Yu et al [41], Xia et al [43], Sondhia and Yaduraju [45], Borowiec et al [46], Li et al [47], and Sondhia et al [48] and in agreement with TLC detection method for analysis of atrazine and diuron [39]. This shows that the TLC separation and detection of various pesticide residues can be carried out in the laboratory with appropriate reproducibility that enables the use of the TLC methods for cost-effective screening of a large number of environmental samples, or for the confirmation of the analytes where confirmation of pesticide cannot be done due to unavailability of GC or LC/MS/MS.…”
