What is the best pre emergent fertilizer?

The Best Pre-Emergent Herbicides:

• Prodiamine (Barricade equivalent) is the longest-lasting, and most economical due to lowest application rates.
• Isoxaben (Gallery equivalent) prevents a very large list of Broadleaf Weeds.
• Oxadiazon (Ronstar equivalent) is a great granular option – safe in all turf and ornamentals.

Likewise, can I fertilize after pre emergent?
