What crops is Opti-DGA labeled for?

What is the active ingredient in Opti-DGA? Is it a generic?

Build a program →Can I tank-mix Opti-DGA?
It depends on your target weeds, crop stage, and which partners the label approves. Build a program and FieldMarshal checks the label for approved partners and cites the condition on each, so you can verify it.
Build a program →Plan in minutes, not evenings.
Start with Opti-DGA and let FieldMarshal build a defensible herbicide program for your field, every product, rate, and plant-back cross-referenced and cited.
