Glyphosate hormesis mitigates the effect of water deficit in safflower (Carthamus tinctorius L.).

Low doses of glyphosate can act as mitigators of water deficit in C. tinctorius, allowing plants to maintain their metabolism, reaching levels close to those of plants without water stress, as observed for plant height and leaf area. Our findings indicate that there are even greater implications for understanding glyphosate hormesis in plants under drought conditions, given the current climate change scenario. © 2020 Society of Chemical Industry.
