In a field experiment investigated the effect of soil herbicides (Harnes, Frontier, Merlin) on prooxidant-antioxidant balance in the vegetative organs of Zea mays L. Shown that the human factor leads to increased lipid peroxidation, as evidenced by the high content of prooxidant components (diene and triene conjugates, TBA-active products). Found a protective increase in activity of superoxide dismutase, catalase and peroxidase in roots and leaves of corn.
