Tenacity takes care of all my grassy weed problems. However, it does not offer eradication of Poa Annua; can the two chemicals be mixed together, therefore solving all grassy weed problems with one application? I would also use a nonionic surfactant.
The label for Poa Constrictor does not mention anything about tank mixing with another herbicide such as Tenacity Herbicide. Per the Tenacity label: Other tank mixture partners may be safe but have not been tested. Turf managers wanting to tank mix Tenacity with other herbicides should test on a small basis for compatibility, safety and efficacy before treating large areas. We would recommend doing a compatibility test before treating.
