The Power Behind Double Team Sorghum.

Order Seed

The Seed Foundation of the Double Team System

Warner Seeds provides the sorghum genetics and DT Trait® technology that make the Double Team system possible. DT Trait hybrids are non-GMO and developed to tolerate FirstAct® herbicide. Hybrid selection still matters: choose genetics for your environment, then confirm whether the seed contains DT1 or DT2 so the correct application guidance follows the field.

What is the DT Trait?

The DT Trait is a non-GMO herbicide-tolerance trait in designated grain sorghum hybrids. It enables labeled postemergence applications of FirstAct herbicide when the correct hybrid, crop stage, rate and stewardship practices are followed.

DT1 and DT2 are NOT Interchangeable

Both trait generations belong to the Double Team system and pair with FirstAct, but their crop-stage application guidance differs. Always verify whether the seed contains DT1 or DT2 so the correct herbicide application guidance follows the field.

How Do I Know Which Trait I Planted?

Check the seed bag, seed tag, product name and purchase records for the DT1 or DT2 designation. Keep that identification with field records and communicate it to the applicator. If the trait cannot be confirmed, do not assume the application window—contact the seed retailer or Warner Seeds.

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.
