Opportunity FAQ

What crops is Opportunity labeled for?

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

Opportunity's active ingredient is glufosinate (MOA Group 10). Other products list the same active ingredient; rates, formulations, and labeled crops differ — verify each on its own label.

What's the plant-back interval after Opportunity?

Can I tank-mix Opportunity?

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.
