Daniel from Weidman writes
The product label of Poa Constrictor Herbicide only provides tank mixing instructions with liquid fertilizers as a spray applications and does not provide permissions or restrictions for tank mixing with other herbicides. We recommend conducting a small jar test and following the most restrictive product label instructions. NOTE: This product has been discontinued therefore we recommend contacting the manufacturer directly at 800-438-6071 for more information.
