Information technologies of remote assessment of herbicide consequences on winter rape crops

Abstract

A separate group of substances with potential phytotoxicity are herbicides. These chemicals contain potent biologically active substances designed to destroy certain types of vegetation. Residues of some of these substances can be stored in the soil for several years, showing interaction with other substances and, undesirably, a negative effect on cultivated plants. With increasing use and range of herbicides, the risk of aftereffects increases significantly. A clear description of the drugs, the mechanism of their action is indicated in the regulations of their use. However, in production, as a rule, there are subjective and objective factors, as well as a number of random factors that can lead to the manifestation of adverse effects or after-effects of drugs. 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.
