Measures to protect plants from various pathogens should be carried out over a certain period of time to avoid possible economic losses. Complex mobile systems are needed to monitor the susceptibility or resistance of various plant crops. The report presents a setup that allows recording signs of metabolic disorders in agricultural crops at the early development stage using direct atmospheric absorption in the IR range. The characteristics of the equipment used are provided. The methodology of the approach to processing primary experimental data is described. A series of experiments were conducted on a standard FT-801 Fourier spectrometer. A greenhouse measuring 50 cm wide and 200 cm long was used as a working volume. A representative sample of plants consisted of 35 pieces. It is shown that the spectroscopic approach allows recording the presence of infection 5 days before the appearance of the corresponding morphological features in plants.
