The article presents the study results of specific activity and multiple forms of peroxidase and catalase as antioxidant enzymes in leaves and seeds of Garmoniya soybean variety in oxidative stress conditions caused by herbicides. It has been found that herbicides not only destroy weeds, but also have an effect on cultivated plants. Significantly low specific peroxidase activity in soybean leaves was identified in crops treated with Pulsar herbicide. High specific peroxidase activity and increased number of multiple forms (14) in soybean leaves was caused by Pivot herbicide exceeding control by almost three times, which was confirmed by a slowdown in growth and development of soybean plants by reducing the intensity of growth processes and, accordingly, increasing their resistance to withstanding adverse conditions caused by exposure to chemical substances - herbicides. Analysis of specific activity and multiple forms of catalase in soybean seeds of the 2018 and 2019 harvest showed differences in enzyme activity and number of forms depending on the herbicides used. Changes in enzymes’ activity and the number of their forms indicate a change in metabolic processes occurring when using herbicides depending on their chemical nature, which provides plant resistance to stress.
