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

Build a program →Can I tank-mix Orador?
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.
