The determination of fungicides particularly the carbendazim and mancozeb could not be done satisfactorily using chromatograph techniques as they undergo fast decomposition when dissolved in solvents for sample preparation. Hence the suitability of the Fourier Transform Infrared Spectroscopy (FTIR) was tested for the rapid identification of fungicide active ingredients viz., carbendazim, mancozeb, copper oxychloride and sulphur in commercial formulations. This was achieved through targeting the characteristic wavenumbers, functional groups and vibration types of each molecule through measuring FTIR spectra over 4000-400 cm-1 range at the spectral resolution of 8 cm-1 with the 1024 scans. The FTIR spectrum of each compound was compared with the online database to confirm their identity. The present technique is found to be a true, alternative over lengthy and repetitive chromatograph method, which are commonly recommended for the quality assurance of market-accessible formulations. The present approach is rapid and offers green technology as it involves less sample, solvent, energy and waste generations.
