Introduction. Failure to comply with the rules and regulations in the pesticides application can lead to environmental pollution, in particular, soil and groundwater occupy the first place by pol-lution level.
The purpose of the study was to assess the potential ecotoxicological hazards of Stratos Ul-tra herbicide and its active substance cycloxydim, the risk of contamination of surface and groundwa-ter by cycloxydim.
Materials and methods of research. An estimation of the environmental hazard of Stratos Ul-tra herbicide has been carried out on the basis of ecotoxicological hazard assessment (ecotox), inte-gral hazard vector (R), groundwater ubiquity score (GUS), leaching potential (LEACH) indices.
Results. It was established that in the soil and climatic conditions of Ukraine the ecotoxicolog-ical risk of Stratos Ultra herbicide on cycloxydim basis application is 7,23×10-5, the persistence index is -0,22 week, the GUS index is 2,01, the LEACH index 7,19 and the integral vector (R) is 94 points.
Conclusions. It was shown that when applying the herbicide Stratos Ultra, the ecotoxicologi-cal risk of cyclooxydim is 5 orders of magnitude lower than that of DDT. According to the index of groundwater ubiquity score (GUS) the substance is classified as an average hazardous, by the inte-gral vector (R) and the LEACH index corresponds to a high level of ground and surface water pollu-tion risk, according to the persistence index a low level of soil contamination by the studied herbi-cide.
