You could mix a post-emergent herbicide or different pre-emergent herbicide with Prodiamine 65 WDG as long as the use sites are compatible, you are not using the same active ingredient in multiple products, and you calibrate the products to be used together. Any time you are mixing products together for the first time, it is recommend to perform a small test mixture first to ensure compatability.

Another option would be to use a different pre-emergent, such as Dimension 2EW, which also lists Dandelion on the label.
