The biological and economic effectiveness of plant protection measures depends not only on the correct choice of pesticide, but also on the quality of its application to the processed target objects. The article discusses the results of assessing the quality of applying herbicides by spraying using low-volume spraying technology, ULV spraying without forced and forced precipitation of small droplets, and treatment with cold aerosol. To assess the impact of the quality of the application of plant protection products on the environmental safety of the use of herbicides, two main indicators were used: – uniform distribution of the working fluid over the treated area: – the amount of drift of small drops from the treatment area. The analysis of methodological approaches and regulatory documents for assessing the potential risk of pesticides for the environment in European countries and in Russia is given.Based on the obtained experimental data on the coefficients of variation in the distribution of the drug over the effective coverage width, an expert assessment of the drug overuse was carried out using various technologies. An expert assessment of the drift of small drops of the working fluid from the treatment zone was also carried out. A comparative assessment of technologies was carried out according to the indicated environmental safety indicators for the use of the herbicide Gezagard WP on potato plantings.
