To ensure the safety of the environment and human health, the manufacture of pesticide formulations must be in accord with registered formula components. The Agricultural Chemicals Inspection Station therefore regularly inspects the formula components of commercial samples. The purpose of this paper is to introduce a simple method using Fourier transform infrared attenuated total reflection (FT-IR/ATR) spectroscopy for the identification of the formula components of registered and commercial samples. The FT-IR/ATR technique is fast and relatively easy to use; it requires no sample pretreatment for most solid and liquid pesticide formulations, with the exception of some ready-to-use liquid formulations. The transmittance spectrum (4,000-650 cm^<-1>) is useful for inspection. We used three evaluation methods to identify the components of the formula: overlap of two spectra, calculation of the purity index, and use of principal component analysis (PCA).
