How soon after applying Barricade 4FL Pre-Emergent Herbicide should it be watered in?

I'm hoping to apply the day before a rain. Is this okay? It'll likely dry then get watered in.

Answer:

Ideally watering in is done right after application of Barricade 4FL Pre-Emergent Herbicide but can be within 7 days of application. Timing your treatment with the rainfall is the best way to go as long as not too much!  It only needs to be watered in ½ inch.
