Application

Clodinafop-Propargyl is primarily used as a post-emergence herbicide to control grassy weeds in wheat, barley, and other cereal crops. It inhibits acetyl-CoA carboxylase (ACCase), disrupting fatty acid synthesis in susceptible plants. This herbicide is valued for its selectivity, effectively targeting weeds without harming crops. Researchers also study its environmental fate, resistance mechanisms, and potential synergistic effects with other agrochemicals.
