Since Drive XLR8 requires the use of a Methylated Seed Oil Surfactant and a surfactant is not recommended with Triad Select Herbicide, it would not be advised to tank mix these two as it could cause them to separate in the tank mix. 2 separate applications would be recommeneded.
Triad Select Herbicide is not labeled to be used on or near anything edible. It would be recommended to discard anything that was sprayed and keep applications at least 15 feet away. It can injure plants if contact is made.
The rates for Triad Select Herbicide, just like other professional herbicides will vary depending on what type of grass you have. The water amount will vary as well depending on many things, including the equipment being used. You would need to calibrate the sprayer and than use the rate listed on the label per acre for your grass type.
Triad Select Herbicide label does not list wild strawberry but lists other broadleaf weeds. The actives it contains have been shown to control wild strawberry.
