Pramitol 25E actually can be shipped to Colorado.
Per the Pramitol 25E manufacturer, you should wash the area well with soap and water and allow it to dry completely. They recommend putting a barrier over it once it has dried (a towel or a floor mat) for at least a couple of weeks.
The Pramitol 25E has such a long soil residual that you can't really predict how far it may move so would not be advised to apply around anything desirable nor around edibles.
Pramitol 25E Herbicide becomes rainfast in about 4-6 hours. Since this product is a soil sterilant, it will kill any desirable plants, trees, shrubs, and turfgrass near the treated areas. It is recommended to avoid applications on slopes or grades where there is a risk the chemical would come into contact with roots or desirable grass areas.
Please view the full product label for more information.

Per the product label, do not use Pramitol 25E to sloped areas where desirable vegetation or nearby water bodies may be located downhill of the application area, since injury to desirable plants and other vegetation may result
