We have a storage facility in South Texas with a lot of concrete drives. We typically carry around a small spray bottle to spot treat when weeds start coming up in the concrete seams.
You only want to mix up what you plan to use at a time and not keep it stored in a tank sprayer for more than 24-48 hours max if you want it to carry the same potency. Products like Pramitol 25E, if used correctly should only have to be reapplied every year so if you are finding you are having to treat more frequently in areas you used it in, we would suggest using a little higher ratio per 1000 sq/ft and use a higher water volume over that whole area to ensure it is getting deep enough in the soil to set up an adequate long lasting barrier.
