Dandelions are PERENNIALS.

O.K. fine..point taken.

Pre-M, Dimension, Barricade all have mostly annual grasses and broadleaves on the label...with a FEW perennial broadleaves...mainly the ones that are the more shallow-rooted.

But this thread was begun by the fellow talking about dandelions, and suggesting trying to prevent them with a standard turf pre-emergent in February !

That's a different animal !

There is one good pre-emergent for tough-to control perennials like dandelions: Dow's 'Gallery' herbicide.

But the large-scale use of it, in turf at least, just isn't cost-effective for the vast majority of business owners.

Gallery is really sort of the "crem'e-de-la-crem'e" of landscape pre-emergent products, that found a niche in certain higher-end, cost-is-no-factor turf situations, ususally on estates, higher-profile cemetaries, etc.

I am interested about this subject as well.
Bought some Atrazine last year and was gonna try it this year. I may have waited too long but was thinking of using it now.
I have Centipede which was over-seeded (my bad) with annual rye last fall.
The weeds are starting to wake up so here come the Atrazine...
Any suggestions?
BTW: this is for my own yard
