Background. The seed treatment is an important part of chemical crop protection system, a basis of a profitable production and receiving a rich yield. The types of pre-sowing processing of seeds is constantly growing, particularly due to new com¬bined insecticide-fungicide preparations, which protect both against diseases and pests.
Purpose of the study. The assessment of conditions of safe application of insecticide-fungicides Celest Top 312,5 FS and Celest Maxx 165 FS in pre-sowing processing of cereals seeds.
Materials and methods. The assessment of work conditions was made, using the results of determination of thiamethoxam, difenoconazole, fludioxonil, tebuconazole in the air of the working zone, in washings from the exposed skin and stripes on overalls. The determination of the content of active ingredients was performed by gas-liquid and high performance liquid chromatography.
Results. It is established that the content of active ingredients in the working zone air during treatment of seeds with Celest Top 312,5 FS and Celest Maxx 165 FS and sowing of the treated seeds, does not exceed the established hygienic standards. On the exposed parts areas of the skin active ingredients were found in small quantities; on overalls they were ether not deter-mined or their content did not exceed the limit of detection. The application of Celest Top 312,5 FS and Celest Maxx 165 FS, when following the technology of seed treatment and sowing, did not lead to contamination of air, soil and water in real conditions of their use.


Key words: seed treatment, thiamethoxam, difenoconazole, fludioxonil, tebuconazole, work conditions
