If you choose to apply a herbicide on difficult to control broadleaved weeds, then make sure the product contains what active ingredient?

A widely used herbicide is specific to broad-leaved leaves plants. These herbicides have the main chemical component, an Acetic acid. Acetic acid utilizes the natural indo-3 acetic-acid (IAA), an auxin that promotes an uncontrolled plant growth. Other herbicides with similar components that have synthetic auxins include Dicamba and fluroxypyr.
