Seeding after spraying weeds

[Nbuuifx]

We had a patch of worn down paddock where the horses had been walking to access the other parts of the field. This has grown as many, I'm talking thousands, of little docks.

I'm planning on spraying them with some graze on pro, before the get too big. Once treated though, how long do I need to wait before seeding with some paddock grass seed?

Same day is fine, weed killer needs leaves to work

Thanks, my only concern was that the instructions said something about not putting on new grass
