Information Technology for Remote Evaluation of After Effects of Residues of Herbicides on Winter Crop Rape

Thifensulfuron-methyl is an active substance of herbicides, highly toxic to sensitive plant species. It is used for controlling weeds in predecessor culture can cause damage to crops next year, such as rape. In rape growing, the early detection of the toxic effects of herbicide is critical for reanimation or other crops. Glyphosate in rape causes metabolic disorders in plants that affects their spectral characteristics. This makes it possible to use spectral remote sensing for early detection of damage. In order to determine the possibility of using spectral monitoring from the platform of an unmanned aerial vehicle (UAV), research was carried out at the industrial fields and experimental experimental field of NUBiP of Ukraine, in the optical range, using the RGB camera and the Slantrange complex. The image processing was carried out using firmware (software), as well as the standard and stress indexes provided by the developer. Data obtained from the FC200 optical camera in RGB format was computed in the mathematical package MathCAD.It was found out that in winter crop rape, in the vegetative phase of 5-7 leaves, as a result of the action of the herbicide occurs anomalous coloring of the two lower leaves of the plant. To identify this feature in the optical range, the most informative are red and green channels. With the use of Slantrange 3 complex among the embedded stress indexes, SlantView software is the most informative of Veg. Fraction and Yield potential. It is shown that in order to increase the reliability of the data obtained, it is advisable to carry out additional research on the parameters of debugging the given system.
