Take On Grass Pressure with the Complete Double Team System

Double Team® pairs grain sorghum hybrids containing the non-GMO DT Trait® with FirstAct® herbicide for postemergence control of labeled grass weeds. Warner Seeds brings the seed genetics and trait expertise. ADAMA brings the companion herbicide and crop-protection expertise. Together, they create one integrated sorghum cropping system.

What is Double Team?

Double Team is a two-part sorghum cropping system. DT Trait hybrids provide tolerance to FirstAct herbicide. FirstAct controls labeled grass weeds when applied to the correct DT Trait hybrid according to the current label and stewardship requirements. Both components are essential: the trait protects the crop; the herbicide delivers the grass control.

Two Partners. One System.

Warner Seeds develops, produces and supports sorghum hybrids containing the DT Trait.

ADAMA manufactures and supports FirstAct, the required companion herbicide.

Seed selection, herbicide planning and stewardship should be coordinated before planting so the complete system is ready when application timing arrives.

Know Your Trait Before You Spray

Double Team hybrids may contain DT1 or DT2. The application window and crop-stage guidance are not interchangeable. Confirm the trait designation on the seed bag, seed tag and purchase records, then follow the current FirstAct label and Double Team stewardship guide for that trait. If you are unsure which trait was planted, contact your seed supplier before application.

Is Double Team a Fit?

Double Team is designed for grain sorghum acres where postemergence grass management is an important need. Start with the field’s weed spectrum, rotation plan and hybrid fit. Then confirm local seed and FirstAct availability with your Warner Seeds and crop-protection retailers.

Seeding Rate

If planting in 20 inch rows or less always use the higher rates. Increase seeding rate by 20% if planting is delayed significantly to account for lower tillering rates.
