DT1 vs. DT2 Sorghum:

What Growers and Applicators Need to Know

DT1 or DT2? Know Before You Spray

DT1 and DT2 are two generations of the non-GMO DT Trait® used in the Double Team system. Both are designed for use with FirstAct® herbicide, but the application guidance differs. The trait designation—not simply the Double Team name—must be confirmed before application.

Why It Matters

Using guidance for the wrong trait generation can put crop safety, performance and stewardship compliance at risk. Trait verification should be treated like checking the product, rate and field before every application.

(Double Team) was one of our better yielding fields of grain sorghum this year.

Double Team Sorghum has provided a viable - and potentially superior option - from traditional grain crops, at a most efficient cost of production.

With the Double Team technology, we can now grow grain sorghum on acres that we could not in the past.

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.
