How does atrazine affect photosynthesis

WebAtrazine also has a direct impact on brain health. In our central nervous system, atrazine alters the levels of dopamine and norepinephrine levels. It also decreases the electrical activity of certain cells in the cerebellum, the area of the brain that controls motor movements (6). WebFeb 14, 2024 · atrazine. How does atrazine work? Atrazine interferes with photosynthesis in some broadleaf plants and grasses.2,4 It is taken up by roots and leaves and moves upward in the plant to areas of new growth.2 The plant dries out and dies. Older leaves on plants may be affected more than new leaves. Root growth is not affected by atrazine.4
