We would not recommend tank mixing the SpeedZone Lawn Weed Killer Concentrate and Tenacity if you are using Tenaicty as a post emergent. Tenacity requires a non ionic surfactant to be added if being used to treat actively growing weeds and since a surfactant is NOT recommended with Speedzone, this could cause injury to the lawn. If Tenacity is being applied for pre emergent applications, you can tank mix these two after a small compatibility test is done to ensure they mix properly.
You can use Speedzone Speedzone the same day as Tenacity Herbicide for more broadleaf weed control. Just allow areas to dry between treatments.
SpeedZone Lawn Weed Killer Concentrate should only be applied to well established lawns and well rooted sod.
Per the manufacturer ,evidence of injury can be seen within hours of application, and plants will die in 7 to 14 days once treated with SpeedZone Lawn Weed Killer Concentrate .

Yes, Speedzone Lawn Weed Killer will likely harm the pachysandra as well since it is considered a broadleaf plant.
Speedzone is an herbicide and not an insecticide. If you were to spray flowering plants with Speedzone, then they will die from the herbicide and, therefore, would not cause long-term effects on pollinators in the area. We do not recommend spraying this or other herbicides in a way that would contact pollinators directly or areas such as directly around bee hives.

Unfortunately, there is nothing labeled to treat rescuegrass post emergently in your Bermudagrass. For post emergent control, you would need to spot treat with a non-selective like Roundup QuikPro and reseed/sod. You can use a pre-emergent labeled for rescuegrass to help prevent it from coming up the following season. You would apply it in the spring and the fall and it will prevent the rescuegrass and other weeds from germinating and coming up.
