Pinoxaden
Type: Herbicide
Mode of Action: Inhibiting the enzyme acetyl-CoA carboxylase (ACCase)
Common Product Names: Axial
What is it?
Pinoxaden is a selective post-emergent herbicide, meaning it is applied after the weeds have emerged. It is primarily used to control annual grass weeds in cereal crops such as wheat and barley. The compound is absorbed by the leaves and shoots of the weeds, ensuring thorough coverage and effectiveness. Pinoxaden is known for its quick action, with visible results typically seen within a few days of application.
How does it work?
Pinoxaden's mechanism involves the inhibition of the ACCase enzyme, crucial for lipid biosynthesis in grass weeds. Once absorbed, it disrupts the weed's ability to produce fatty acids, leading to a breakdown in cell membrane function and eventual plant death. This targeted approach ensures minimal impact on broadleaf plants and the cultivated crops themselves.
