What is the active ingredient in IMIFLEX? Is it a generic?

What's the plant-back interval after IMIFLEX?

Build a program →Can I tank-mix IMIFLEX?
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 gives the condition on each, so you can verify it.

Start with IMIFLEX and let FieldMarshal build a defensible herbicide program for your field, every product, rate, and plant-back cross-referenced and checked against the label.
