I feel like it is really not necessary since my St. Augustine is already fairly weed free and grows plenty fast enough in the heat of summer. What am I missing?

If you’re happy with your grass and don’t see weeds, then don’t waste the time or money. Treating with a pre-e like prodiamine blocks crabgrass and some other weeds from growing. So while you might not see them now, they could germinate and grow later.

Now. There is no time restriction to apply pre-emergent herbicide following a post-emergent herbicide application, other than allowing the post-emergent herbicide to dry first, assuming it’s a liquid. Two completely different modes of action where one targets germinating weed seeds, the other seedling or mature weeds.


So mixing prodiamine, 2,4-D, and atrazine together would be a no no?

You can mix. I’m currently spraying barricade, rhomene, and clash at the same time.

Ran out of cleggs mix and was thinking of doing this as a pre emergent because nutsedge is usually a bitch on my zoysia



Bad idea for a wide spread application?

I think Image is a post-emergent.

Cleggs mix and that image product aren’t pre em’s. While the atrazine in the cleggs mix does have some residual pre em’s effect both are considered post em’s.

Nutsedge seems to have started to come up already and I had 0 success fighting it with sedgehammer last year. Any tips for anything I can do now?

Vexis - for sedge?

Someone linked this in a thread last year. It says it helps control sedge. I haven’t tried it but will this year. I have sections of sedge that I have not been able to eliminate. When it grows, I can kill it with either dismiss or certainty or image for sedge. This year I will try Vexis however. At least in my yard, the sedge doesn’t seem to become active until closer to summer. I’m going to put this out probably in march but that may be too late. I’m still reading up on it.

I tried Vexxis in my St Aug yard. Pretty confident I applied it correctly. Maybe helped a little, but otherwise ineffective. Hope you get different results. Maybe using it early before it’s really growing is the way.

My focus this year is on lespedeza. I guess I'll use atrazine then put out some nitrogen for the fist time in my life.
