The control of diseases and pests in vineyards and forestry plantations is one of the main measures to ensure a high level of production. The successful application of control measures requires knowledge of both pests, pathogens, substances and the technical means used to carry out the control in practice. Reducing the consumption of insecticides, fungicides and herbicides is a major requirement imposed on modern sprayers and machines from the conception – design – manufacturing phase to the exploitation phase, diminishing the harmful impact of the techni-cal system on the environment and achieving special economic indicators. In many countries, the trend towards using the latest technologies and moving to precision agriculture, sometimes called smart agriculture, is growing. For a long time, planes and helicopters intended for certa-in mandatory activities in plant-engaged branches (horticulture, forestry, etc.) have been used worldwide. Now, an increasingly important role is played by intelligent aerial drones (UAV, Unmanned Aerial Vehicle), or drones with a high degree of autonomy and accuracy. Purpose. The aim of the research was to evaluate the effectiveness of low-volume spraying of the vineyards with the help of the Unmanned Aerial Vehicle (UAV), with the support of the Agri Assistant application.
