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. 23, 332-334 (2010). TLC of fenvalerate, cypermethrin, and deltamethrin (as standards and extracted from minced visceral tissue) on silica gel with petroleum ether - diethyl ether 9:1 in a previously saturated TLC chamber. Detection by spraying successively with 10 % sodium hydroxide and then with 0.2 % p-benzoquinone in dimethyl sulfoxide. The LOD were approximately 0.25, 0.5, and 0.25 µg/zone for cypermethin, fenvalerate, and deltamethrin, respectively. Organochloro, organophosphorus, carbamate insecticides and pyrethroid insecticides without a cyanide group do not interfere.

Chinese J. Chem. Anal. (Lihua Jianyan, Huaxue Fence) 26, 371, 372 (1990). TLC of 4-hydroxy-3-(1-tetrahydronaphthalenyl)-coumarin (a raticide) on silica with chloroform - methanol 99:1.

J. AOAC Int. 82, 25-30 (1999). Validation of video densitometric and classical slit-scanning determinations of pesticides on TLC plates for linearity, precision, and detection limit. A comparison of results showed that slit-scanning is more sensitive and more precise than video densitometry. According to validation requirements the relative standard deviation of 3.5 - 5.3% for video densitometry is, however, acceptable . Linearities are considered as very good and almost identical for both techniques. The main advantage of video technology is the speed of a few seconds compared with 20 min with scanning densitometry; it provides excellent archiving facility, and image and chromatographic data can be stored together, edited, and used for many tasks. TLC of propham, chlorpropham, tetramethrin, a-cypermethrin, diflubenzuron, atrazine on silica gel with methanol - water 4:1.
