The Decis preparation is part of the group of phytosanitary products with low impact on environmental components. On the soil, its action is achieved through the impact on the vital activity of its microbiome, the suppression of the basic fermentation systems and the metabolic processes involved in pedogenesis and plant nutrition. The toxic action of the Decis preparation on the soil microbiome intensifies against the background of treatments with preparations from the group of those with a strong (Nurela-D, Zolon) and moderate (Delan) impact. The impact of the Decis preparation on the human sympathoadrenal system depends on the administered doses. Its action in a dose of 1.2 mg/kg on the level of catecholamines leads to an imbalance of amines, and its use in higher doses (2.0 and 2.4 mg/kg) leads to a sudden increase in the level of adrenaline and noradrenaline in the tissues of the studied organs.
