J. Planar Chromatogr. 2, 297-303 (1989). HPTLC of 10 fungicides (captafol, captan, cymoxanil, dichlofuanid, dithianon, folpet, iprodione, procymidone, vinclozolin, triadimefon) on prewashed silica (100 µm) with toluene - hexane - diisopropyl ether - ethyl acetate 667:20:8:5. Detection and quantitative determination by densitometry.

J. Planar Chromatogr. 13, 176-181 (2000). HPTLC of substituted 2,4-dihydroxythiobenzanilides on RP 18 with water - methanol, and mixtures of methanol - water - 10 mM acetate buffer (pH 4). After drying detection under UV 325 nm.

Clean-up of matrix-rich samples using high-troughput planar solid phase extraction (HTpSPE). Black and green tea samples were spiked with 7 pesticides (acetamiprid, azoxystrobin, chlorpyrifos, fenarimol, mepanipyrim, penconazole, and primicarb) at level 0.01, 0.1 and 1 mg/kg. Extraction with acetonitrile, pre-cleaning by dispersive SPE. TLC on silica gel (prewashed with acetonitrile) of samples applied as rectangles of 3 x 16 mm first with acetonitrile - water 19:1 over 85 mm and after drying for 5 min with acetone - water 7:1 in the opposite direction over 31 mm. Detection under UV 254 and 366 nm and by dipping in primuline reagent (0.2 % in acetone - water 4:1) and detection under UV 366 nm and white light. Elution of target zones into autosampler vials by TLC-MS Interface with acetonitrile - 10 mM ammonium formate buffer 1:1, flow rate 0.2 mL/min. After clean-up the samples are free of caffeine which interferes with pesticide detection.

J. Liquid Chrom. 10, 3659-3671 (1987). TLC of herbicides and plant growth regulators on calcium sulfate and on calcium sulfate containing aluminium oxide, calcium carbonate and p-dimethylamino-benzaldehyde.

Journal of Environmental Science and Health, Part B 46, 557-568 (2011). Review on techniques and applications of TLC and HPTLC for separation, detection, qualitative and quantitative determination and preparative isolation of pesticides. Covered are sample preparation techniques, stationary phases, sample application, mobile phases, development methods using different chambers, detection under UV or by derivatization with various reagents, identification based on hRf values or by online HPTLC-MS, quantification by scanning densitometry or videodensitometry, preparative layer chromatography and thin-layer radiochromatography. Various applications are described. In the review period especially forensic analyses of human and animal samples for pesticides were numerous. The identification and quantification of components from plant extracts with pesticide activity is also reviewed and it is expected that this area will be especially active in the future given the large amount of ongoing worldwide research on phytochemical compounds.
