The article is devoted to the applied aspects of UAV use, namely the monitoring of winter wheat crops in relation to the stresses caused by technological stresses. First of all, this applies to the prolonged action of herbicides left over from the predecessor crop and which cause stress in new crops. The issue has local specifics related to the inconsistency of plant cultivation technologies and to the insufficient study of the impact of the latest plant protection products in domestic soil conditions. Restoration of crop yields is possible with timely identification of the causes of stress, but decision-making time is limited, which requires the introduction of the latest monitoring technologies suitable for industrial scale. In laboratory studies using phytochambers, the presence of both spectral indicators of healthy and affected plants and the difference in their dimensions were recorded. However, such differences can be explained by other stressors, so it was not possible to establish clear criteria for spectral or spectral-spatial monitoring methods that clearly indicated the stress caused by the after-effects of herbicides. In field studies using the Slantrange complex mounted on a DJI Matrice 600 UAV as an object of study, the distribution of stress areas in the field was analyzed. It was found that, in purely spectral and spectral-spatial monitoring of winter wheat, it was not possible to reliably identify the stressful nature caused by the aftereffects of herbicides, ie ground platforms for spectral sensor equipment are ineffective. It is proved that the maps of stress indices obtained on the basis of high-resolution data from UAVs can be considered as a separate object of research on the interpretation of the causes of stress of complex biotechnical objects such as crops. Improving the reliability and reliability of monitoring data can be achieved by implementing systems of machine data processing and computer training to find correlations between the distribution of stress in plants in the field and the implementation of technological operations, terrain.
