    Testimonials

    Colton Katz in field treated with Flexstar GT

    “If you have a Palmer amaranth or a morningglory problem in your soybeans, nothing is even close to what fomesafen – Flexstar GT 3.5 herbicide – will do for you.”

    Rick Johnson in field treated with post emergence herbicide Flexstar GT

    “We rely on a tank-mix partner with Flexstar GT 3.5 to get that longer residual. We apply a residual with our burndown, too, so we try to overlap them to get the soybeans to canopy. We’ve had very good success.”
