Even Glyphosate-Resistant Weeds Won't Come Back from this One

Using an all-star formulation for better weed resistance management, Flexstar® GT 3.5 herbicide targets and manages challenging weeds, even those resistant to glyphosate and ALS-inhibitors.

Overview

Flexstar GT 3.5 Herbicide

A key partner in a full-season integrated weed management plan, Flexstar GT 3.5 herbicide promotes the use of two different sites of action. When used in a two-pass system with an effective preemergence herbicide, it can provide overlapping residuals to help prevent or delay herbicide resistance.

        Benefits

        • Combines 2 leading active ingredients – fomesafen and glyphosate – with different sites of action for weed resistance management
        • Contains Isolink® II Technology, a patented formulation designed to optimize the systematic activity of glyphosate and the contact activity of fomesafen
        • Removes the competition of problem grass and broadleaf weeds, to help preserve yields
        • Manages weeds that are difficult to control with glyphosate alone
        • Provides early-season residual control and excellent crop safety
        • Can follow a properly timed preemergence herbicide application of Boundary® 6.5 EC, BroadAxe® XC or Sequence® herbicides
        • Widens the post-emergence application window, manages resistance and helps maximize soybean yield potential when used as part of a 2-pass system

        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.”
