Trends Anal. Chem. 165, 117156 (2023). Review of the use of radiolabeled pesticides to track nanoformulations in biological and environmental scenarios and the application of TLC for evaluating the mobility and degradation of pesticides and nanopesticides. The paper described TLC as tool to quantify the metabolites generated in the biodegradation study.

J. Planar Chromatogr. 35, 643-646 (2022). HPTLC of amitraz in visceral tissue on silica gel with hexane - acetone 4:1. Detection by spraying with 10 % sodium hydroxide solution, followed by heating at 80 °C for 10 min. The plate was then removed and kept for attaining room temperature, followed by spraying with freshly prepared sodium nitrite (1%) in acidic media. Right after, alkaline solution of curcumin (1% in sodium hydroxide solution) was sprayed. The hRF value for amitraz was 63. 

J. Liq. Chromatogr. Relat. Technol. 41, 1052-1065 (2019). Review of the following topics for the period of November 1, 2016 to November 1, 2018: sample preparation for TLC pesticide analysis; lipophilicity and retention studies for the study of biological activity; new reagents for pesticide detection; HPTLC-effect directed analysis on the surface of the layer; TLC-Raman spectrometry for the analysis of thiabendazole, triazophos, and phosmet residues; TLC analysis of radiolabeled pesticides; methods for the separation, detection, and qualitative and quantitative determination of pesticide residues; determination of pesticides in commercial products and the use of TLC for pesticide degradation studies. The review highlighted the isolation, characterization, and determination of less hazardous and less toxic biopesticides from plants, bacteria, fungi, and soil as the most active application area of pesticide TLC today.

J. Planar Chromatogr. 32(1), 51-53 (2019). TLC of amitraz in visceral tissues (stomach, intestine, liver, spleen, and kidney) on silica gel with hexane - acetone 4:1. Detection by spraying with 10 % sodium hydroxide solution, followed by heating at 80 °C for 10 min. The plate was then removed, kept to attain room temperature and sprayed with 5 % chloranil solution. The hRF values were between 49 and 51. The zones were stable for 8 h.

J. Planar Chromatogr. 30, 271-274 (2017). HPTLC of the synthetic pyrethroids cypermethrin, deltamethrin, and λ-cyhalothrin on silica gel with n-hexane – acetone 4:1. Detection by spraying with freshly prepared hydralazine solution (37.5 mg in 50 mL 2N sodium hydroxide solution). The hRF value for α-cyano ester pyrethroids was 57.

J. Chromatogr. 455, 439 (1988). TLC on silica with a) 1,2-dichloroethane - methanol - acetic acid 90:8:2, b) chloroform - methanol 97:3 and c) cyclohexane - 1,2-dichloroethane - acetic acid 75:25:0.6. Detection by spraying with 6 color reagents and examination of the spots in visible light and under UV 254 nm. Detection limits, 1 ˜ 8 µg.

J. Liquid Chromatogr. 17, 1385-1398 (1994). TLC of title compounds on silica with 1) chloroform - acetonitrile - formic acid 87:10:3, and 2) chloroform - acetone 1:3. Detection by exposure to pyridine vapor and densitometry at 366 nm. Detection limit in the range of 0.2 - 1.6 ng for the 5 compounds.

J. Liq. Chromatogr. & Rel. Technol. 26, 147-156 (2003). HPTLC of monensin and lasalocid residues on silica gel with ethyl acetate - hexane 8:3. Visualization by spraying with 5% methanolic vanillin solution and sulfuric acid 199:1 and heating at 90°C for 5 - 15 min. Quantitation by densitometry at 500 nm. Limit of detection was determined at 0.2µg/g for monensin and 1.0 µg/g for lasalocid. The method appears to be specific, linear, repeatable and reproducible, sensitive, convenient and simple to use.
