What crops is Reflex labeled for?

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

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