Designed hygienic standards in the environment and food products (MPC in water bodies of water , in the air of the working area and the atmosphere air; MRLs in food, soil UEC ) . Science-based regulations of safe use of the drug in the agrifarms - sanitary protection zone, time-to-work.

Keywords: pesticide, hygienic standard, defoliant " UzDEF-K", the environment, water, air, soil, food products.

Summary: Plant growth stimulator «DAG-2» is not a source of air pollution of the working area for sowing cotton seeds treated with this drug. However, working conditions and the nature of work processes when sowing tractor cause adverse shifts physiological responses of various systems of the body, there is a likelihood of the risk of professional diseases caused by indicating the need to implement measures to improve working conditions.

Key words: working conditions, harmful production factors, and the functional state of the body, due to the risk of professional diseases.
