Product Overview

Flexstar® GT 3.5 herbicide is specifically formulated to combat weeds that are difficult to manage with glyphosate alone, or are resistant to glyphosate and ALS-inhibitors. It contains 2 leading active ingredients and delivers 2 effective sites of action for use in soybeans and cotton. Flexstar GT 3.5 contains Isolink® II Technology, a unique adjuvant system designed to optimize the systematic activity of glyphosate and the contact activity of fomesafen. 

In soybeans, Flexstar GT 3.5 can be used as part of a full-season weed management system when applied as a follow up to Boundary® 6.5 EC or BroadAxe® XC herbicides.

Product Highlights

  • Combines 2 leading active ingredients, glyphosate and fomesafen
  • Utilizes the Isolink II Technology adjuvant system for improved effectiveness and reduced crop injury
  • Promotes the use of multiple effective sites of action and a system of overlapping residuals to help prevent or delay herbicide resistance when followed by Boundary or BroadAxe XC
  • Combats weeds that are difficult to manage with glyphosate alone

Testimonials

“Flexstar GT 3.5 herbicide keeps our fields clean. I only sprayed one time this year. The residual control was great – we got about 30 days and by that time, the rows had closed up and none of the bad weeds could grow.” Austin Carlson, Grower, Quimby, IA

“We’ve applied Flexstar GT 3.5 herbicide as an early post-emergence herbicide on our soybeans. It’s great on giant ragweed, which is always tough to control in our area. It’s done a great job cleaning up our fields.”  - Ryan Larson, Grower and retailer, Blooming Prairie, MN

The effectiveness of a strong full-season weed management program is even more apparent during bare ground trials, as shown here.

One of the keys to weed resistance management is the use of multiple effective sites of action. The difference in weed control is clear when comparing a glyphosate-only application (left) to the 2 effective sites of action of Flexstar® GT 3.5 (right). Source: Syngenta, 2013.
