The proposed method describes the use of paptode for the determination of the thiram. The method describes chemo sensors developed for the determination of the thiram. The method is based on the thiram is hydrolyzed by HCI and change it in dimethylamine, which are coupled with NEDA and resulting pink magenta color azo dye formed on the paper platform. The color system formed pattern on an inert support. Scanner detects the product on TLC strip and obtained analyzed with program written in visual basic. The proposed sensor in linear in concentration range 100-1000 µg/ml. All analytical parameters and optimum reaction condition was evaluated. The sensors are use to detect, thiram in red sample i.e., soil and vegetable.
