About Pinoxaden

Pinoxaden is a selective post-emergence herbicide belonging to the phenylpyrazole class, primarily used for controlling annual grass weeds in cereal crops. It functions by inhibiting the enzyme acetyl-CoA carboxylase (ACCase), which is essential for fatty acid synthesis in grasses, leading to effective weed control.
