You should contact the product manufacturer (not the distributor/retailer) to verify the mode-of-action (MOA) classification for this herbicide. The contact phone number should be listed on the label. We did not see a mention of classification on the product label either, but we researched each active ingredient separately. We found that prodiamine is MOA group 3 and quinclorac is MOA group 4, which may be why the label does not give a specific mode of action for the blended product. One online retailer assigned Cavalcade PQ a group 3 designation as a whole, but again, it would be prudent to verify this with the manufacturer.
